Bootstrap Panel Collapse

Overview

Very often we need to separate some short (or not so much) sections of content in order to help them stand up and get the guest's interest-- such as listing certain valuable features showing a list of articles along with a brief extract and a single effective image and so on and on.

We require an efficient tool to nicely cover our information in a wonderful and flexible approach to get it favorable and tidy demonstrated on our pages. In the last version of the remarkably famous flexible framework-- Bootstrap 3 we employed mostly the Bootstrap Panel Example, thumbnail and well elements delivering us box containers having a faint border, quite rounded corners and eventually-- a light 3d effect. In the latest Bootstrap 4 framework, these are no more. They get got changed collectively by the card item declaring to be worthy of almost everything the previous features can do but basically better. So it's time to get to learn it better.

How to add the Bootstrap Panel Tabs:

The cards are softly styled boxes capable of carrying practically any HTML content in them as well having a lot of predefined designing choice for correctly showing its content. It also additionally might have a header and a footer.

As discussed before the

.card-block

appears to cover the content remaining a pretty padding around it. The moment it comes to pics this might want to avoid this and get the pic spread the entire width of the section.

To have this appearance just place the

<div class="img"><img></div>

tag outside the

.card-block

so you avoid the paddings eventually adding

style=" width:100%;"

making sure this will resize correctly always filling in its container.

A few words regarding the layout-- cards will occupy the entire horizontal area available by default so it's a good idea controling this by putting them inside some grid elements. By doing this you can get their predictable actions. ( click this)

Some good example

Cards are designed with as little markup and styles as possible, but still operate to provide a plenty of control and customization. Built using flexbox, they present easy placement and combine properly with other Bootstrap components.

Below is a model of a simple card with combined content and a fixed width. Cards have no precise width to start, so they'll naturally fill the whole width of its parent element. This is simply customized with a variety of sizing choices.

<div class="card" style="width: 20rem;">
  <div class="img"><img class="card-img-top" src="..." alt="Card picture caption"></div>
  <div class="card-block">
    <h4 class="card-title">Card caption</h4>
    <p class="card-text">Some fast sample message to build on the card title as well as compose the bulk of the card's material.</p>
    <a href="#" class="btn btn-primary">Go somewhere</a>
  </div>
</div>

Web content kinds

Cards support a large selection of content, including pics, text, list groups, hyperlinks, and more. Below are examples of what's supported.

Blocks

The building block of a card is the

.card-block

Use it whenever you require a padded section within a card.

<div class="card">
  <div class="card-block">
    This is some message in a card block.
  </div>
</div>

Names, text message, and links

Subtitles are utilized by adding a

.card-subtitle

to a

<h*>

tag. In case the

.card-title

and the

.card-subtitle

elements are placed in a

.card-block

element, the card title and subtitle are aligned well.

Names, text, and {links| web links| hyperlinks| urls

<div class="card">
  <div class="card-block">
    <h4 class="card-title">Card title</h4>
    <h6 class="card-subtitle mb-2 text-muted">Card subtitle</h6>
    <p class="card-text">Some fast example message to improve the card title and compose the mass of the card's content.</p>
    <a href="#" class="card-link">Card link</a>
    <a href="#" class="card-link">Another link</a>
  </div>
</div>

Illustrations

.card-img-top

spots a pic to the very top of the card. With

.card-text

, text is put on the card. Text in

.card-text

can also be styled with the standard HTML tags.

<div class="card">
  <div class="img"><img class="card-img-top" src="..." alt="Card picture cap"></div>
  <div class="card-block">
    <p class="card-text">Some fast example message to build on the card title and also compose the bulk of the card's web content.</p>
  </div>
</div>

Listing groups

Make lists of content in a card with a flush list group.

<div class="card">
  <ul class="list-group list-group-flush">
    <li class="list-group-item">Cras justo odio</li>
    <li class="list-group-item">Dapibus ac facilisis in</li>
    <li class="list-group-item">Vestibulum at eros</li>
  </ul>
</div>

Mix and fit various material sorts to produce the card you want, or throw everything in there.Displayed right here are picture formats, blocks, notification designs, plus a list group - all covered in a fixed-width card.

<div class="card" style="width: 20rem;">
  <div class="img"><img class="card-img-top" src="..." alt="Card image cap"></div>
  <div class="card-block">
    <h4 class="card-title">Card title</h4>
    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
  </div>
  <ul class="list-group list-group-flush">
    <li class="list-group-item">Cras justo odio</li>
    <li class="list-group-item">Dapibus ac facilisis in</li>
    <li class="list-group-item">Vestibulum at eros</li>
  </ul>
  <div class="card-block">
    <a href="#" class="card-link">Card link</a>
    <a href="#" class="card-link">Another link</a>
  </div>
</div>

Header and footer

Add an optional header and/or footer within a card.

<div class="card">
  <div class="card-header">
    Featured
  </div>
  <div class="card-block">
    <h4 class="card-title">Unique title therapy</h4>
    <p class="card-text">With supporting message below as an all-natural lead-in to extra content.</p>
    <a href="#" class="btn btn-primary">Go someplace</a>
  </div>
</div>

Card headers can be styled by including

.card-header

<h*>

components.

<div class="card">
  <h3 class="card-header">Featured</h3>
  <div class="card-block">
    <h4 class="card-title">Special title treatment</h4>
    <p class="card-text">With supporting message below as a natural lead-in to extra content.</p>
    <a href="#" class="btn btn-primary">Go someplace</a>
  </div>
</div>

<div class="card">
  <div class="card-header">
    Quote
  </div>
  <div class="card-block">
    <blockquote class="card-blockquote">
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
      <footer>Someone famous in <cite title="Source Title">Source Title</cite></footer>
    </blockquote>
  </div>
</div>

<div class="card text-center">
  <div class="card-header">
    Featured
  </div>
  <div class="card-block">
    <h4 class="card-title">Special title treatment</h4>
    <p class="card-text">With supporting text below as an all-natural lead-in to extra material.</p>
    <a href="#" class="btn btn-primary">Go someplace</a>
  </div>
  <div class="card-footer text-muted">

  </div>
</div>

Proportions

Cards have no definite

width

to begin, so they should be 100% expanded except otherwise stated. You can modify this as needed with customized CSS, grid classes, grid Sass mixins, or utilities. ( click this link)

Operating grid markup

Using the grid, wrap cards in columns and rows as required.

<div class="row">
  <div class="col-sm-6">
    <div class="card">
      <div class="card-block">
        <h3 class="card-title">Special title treatment</h3>
        <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
        <a href="#" class="btn btn-primary">Go somewhere</a>
      </div>
    </div>
  </div>
  <div class="col-sm-6">
    <div class="card">
      <div class="card-block">
        <h3 class="card-title">Special title treatment</h3>
        <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
        <a href="#" class="btn btn-primary">Go somewhere</a>
      </div>
    </div>
  </div>
</div>

Working with utilities

Use handful of offered sizing utilities to rapidly set a card's width.

<div class="card w-75">
  <div class="card-block">
    <h3 class="card-title">Card title</h3>
    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
    <a href="#" class="btn btn-primary">Button</a>
  </div>
</div>

<div class="card w-50">
  <div class="card-block">
    <h3 class="card-title">Card title</h3>
    <p class="card-text">With sustaining message listed below as an all-natural lead-in to extra web content.</p>
    <a href="#" class="btn btn-primary">Button</a>
  </div>
</div>

<div class="card" style="width: 20rem;">
  <div class="card-block">
    <h3 class="card-title">Special title treatment</h3>
    <p class="card-text">With supporting text below as a natural lead-in to added material.</p>
    <a href="#" class="btn btn-primary">Go somewhere</a>
  </div>
</div>

Text message arrangement

You can quickly transform the message placement of any kind of card-- in its whole or details components-- with text align classes.

<div class="card" style="width: 20rem;">
  <div class="card-block">
    <h4 class="card-title">Special title treatment</h4>
    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
    <a href="#" class="btn btn-primary">Go somewhere</a>
  </div>
</div>

<div class="card text-center" style="width: 20rem;">
  <div class="card-block">
    <h4 class="card-title">Special title treatment</h4>
    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
    <a href="#" class="btn btn-primary">Go somewhere</a>
  </div>
</div>

<div class="card text-right" style="width: 20rem;">
  <div class="card-block">
    <h4 class="card-title">Special title treatment</h4>
    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
    <a href="#" class="btn btn-primary">Go somewhere</a>
  </div>
</div>

Site navigating

Include some navigation to a card's header (or block) with Bootstrap's nav elements.

<div class="card text-center">
  <div class="card-header">
    <ul class="nav nav-tabs card-header-tabs">
      <li class="nav-item">
        <a class="nav-link active" href="#">Active</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Link</a>
      </li>
      <li class="nav-item">
        <a class="nav-link disabled" href="#">Disabled</a>
      </li>
    </ul>
  </div>
  <div class="card-block">
    <h4 class="card-title">Special title treatment</h4>
    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
    <a href="#" class="btn btn-primary">Go somewhere</a>
  </div>
</div>

<div class="card text-center">
  <div class="card-header">
    <ul class="nav nav-pills card-header-pills">
      <li class="nav-item">
        <a class="nav-link active" href="#">Active</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Link</a>
      </li>
      <li class="nav-item">
        <a class="nav-link disabled" href="#">Disabled</a>
      </li>
    </ul>
  </div>
  <div class="card-block">
    <h4 class="card-title">Special title treatment</h4>
    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
    <a href="#" class="btn btn-primary">Go somewhere</a>
  </div>
</div>

Images

Cards provide some features for working with pictures. Choose from appending "image caps" at possibly end of a card, overlaying pics with card content, or simply installing the image in a card.

Image caps

Just like footers and headers, cards may involve bottom and top "image caps"-- pictures at the top or bottom of a card.

<div class="card mb-3">
  <div class="img"><img class="card-img-top" src="..." alt="Card image cap"></div>
  <div class="card-block">
    <h4 class="card-title">Card title</h4>
    <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
    <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
  </div>
</div>
<div class="card">
  <div class="card-block">
    <h4 class="card-title">Card title</h4>
    <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
    <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
  </div>
  <div class="img"><img class="card-img-bottom" src="..." alt="Card image cap"></div>
</div>

Picture cover

Turn a pic into a card background and overlay your card's text. Basing on the image, you may or may not need

.card-inverse

(see below).

<div class="card card-inverse">
  <div class="img"><img class="card-img" src="..." alt="Card image"></div>
  <div class="card-img-overlay">
    <h4 class="card-title">Card title</h4>
    <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
    <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
  </div>
</div>

Card varieties

Cards feature various alternatives for modifying their backgrounds, borders, and color.

Inverted text message

By default, cards use dark text and expect a light background. You can reverse that by toggling the color scheme of text within, as well as that of the card's subcomponents, with

.card-inverse.

Specify a dark

background-color

and

border-color

to go with it.

You can also use

.card-inverse

having the contextual backgrounds variants.

<div class="card card-inverse" style="background-color: #333; border-color: #333;">
  <div class="card-block">
    <h3 class="card-title">Special title treatment</h3>
    <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
    <a href="#" class="btn btn-primary">Go somewhere</a>
  </div>
</div>

Background variations

Cards include their own variant classes for swiftly changing the

background-color

and

border-color

of a card. Darker colors request the use of

.card-inverse

<div class="card card-inverse card-primary mb-3 text-center">

Sharing meaning to assistive modern technologies

Employing color to add meaning only delivers a visual indication, which will not be conveyed to users of assistive technologies-- like screen readers. Ensure that information signified by the color is either evident from the material itself (e.g. the visible text), or is featured through different means, including extra content hidden with the

.sr-only

class.

Outline cards

Need a colored card, but not the hefty background colors they bring? Replace the default modifier classes with the

.card-outline-*

ones to design just the

border-color

of a card.

<div class="card card-outline-primary mb-3 text-center">
  <div class="card-block">
    <blockquote class="card-blockquote">
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>

Card placement

Along with styling the content within cards, Bootstrap 4 adds a number of options for laying out series of cards. For the time being, such layout choices are not yet responsive.

Card groups

Utilize card groups to render cards as a single, connected item with identical width and height columns. Card groups work with

display: flex;

to achieve their uniform sizing.

<div class="card-group">
  <div class="card">
    <div class="img"><img class="card-img-top" src="..." alt="Card image cap"></div>
    <div class="card-block">
      <h4 class="card-title">Card title</h4>
      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
  <div class="card">
    <div class="img"><img class="card-img-top" src="..." alt="Card image cap"></div>
    <div class="card-block">
      <h4 class="card-title">Card title</h4>
      <p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
  <div class="card">
    <div class="img"><img class="card-img-top" src="..." alt="Card image cap"></div>
    <div class="card-block">
      <h4 class="card-title">Card title</h4>
      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
</div>

When utilizing card groups with footers, their content is going to automatically line up.

<div class="card-group">
  <div class="card">
    <div class="img"><img class="card-img-top" src="..." alt="Card image cap"></div>
    <div class="card-block">
      <h4 class="card-title">Card title</h4>
      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
    </div>
    <div class="card-footer">
      <small class="text-muted">Last updated 3 mins ago</small>
    </div>
  </div>
  <div class="card">
    <div class="img"><img class="card-img-top" src="..." alt="Card image cap"></div>
    <div class="card-block">
      <h4 class="card-title">Card title</h4>
      <p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
    </div>
    <div class="card-footer">
      <small class="text-muted">Last updated 3 mins ago</small>
    </div>
  </div>
  <div class="card">
    <div class="img"><img class="card-img-top" src="..." alt="Card image cap"></div>
    <div class="card-block">
      <h4 class="card-title">Card title</h4>
      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p>
    </div>
    <div class="card-footer">
      <small class="text-muted">Last updated 3 mins ago</small>
    </div>
  </div>
</div>

Card decks

Required a set of equal width as well as height cards that aren't attached to each other? Use card decks.

<div class="card-deck">
  <div class="card">
    <div class="img"><img class="card-img-top" src="..." alt="Card image cap"></div>
    <div class="card-block">
      <h4 class="card-title">Card title</h4>
      <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
  <div class="card">
    <div class="img"><img class="card-img-top" src="..." alt="Card image cap"></div>
    <div class="card-block">
      <h4 class="card-title">Card title</h4>
      <p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
  <div class="card">
    <div class="img"><img class="card-img-top" src="..." alt="Card image cap"></div>
    <div class="card-block">
      <h4 class="card-title">Card title</h4>
      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
</div>

Just like with card groups, card footers in decks will automatically line up.

<div class="card-deck">
  <div class="card">
    <div class="img"><img class="card-img-top" src="..." alt="Card image cap"></div>
    <div class="card-block">
      <h4 class="card-title">Card title</h4>
      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
    </div>
    <div class="card-footer">
      <small class="text-muted">Last updated 3 mins ago</small>
    </div>
  </div>
  <div class="card">
    <div class="img"><img class="card-img-top" src="..." alt="Card image cap"></div>
    <div class="card-block">
      <h4 class="card-title">Card title</h4>
      <p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>

Card columns

Cards may be arranged into Masonry-like columns along with just CSS by wrapping them in

.card-columns

Cards are developed with CSS

column

properties instead of flexbox for easier alignment. Cards are ordered from top to bottom and left to.

Carry on! Your mileage with card columns may differ. To prevent cards breaking across columns, set them to

display: inline-block

column-break-inside: avoid

isn't a bulletproof solution yet.

<div class="card-columns">

    <div class="img"><img class="card-img-top img-fluid" src="..." alt="Card image cap"></div>
    <div class="card-block">

      <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>

Card columns may additionally be expanded as well as personalized with some extra code. Revealed below is an expansion of the

.card-columns

course utilizing the same CSS-- CSS columns-- to produce a collection of responsive tiers for transforming the number of columns.

.card-columns

    column-count: 4;
  
  @include media-breakpoint-only(xl) 
    column-count: 5;
