Stretched link

Make any HTML element or Bootstrap component clickable by “stretching” a nested link via CSS.

Add .stretched-linkto a link to make its containing block clickable via a ::afterpseudo element. In most cases, this means that an element with position: relative;that contains a link with the .stretched-linkclass is clickable. Please note given how CSS positionworks , .stretched-linkcannot be mixed with most table elements.

Cards have position: relativeby default in Bootstrap, so in this case you can safely add the .stretched-linkclass to a link in the card without any other HTML changes.

Multiple links and tap targets are not recommended with stretched links. However, some positionand z-indexstyles can help should this be required.

Card with stretched link

Some quick example text to build on the card title and make up the bulk of the card's content.

go somewhere

<div class="card" style="width: 18rem;">
  <img src="..." class="card-img-top" alt="...">
  <div class="card-body">
    <h5 class="card-title">Card with stretched link</h5>
    <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>
    <a href="#" class="btn btn-primary stretched-link">Go somewhere</a>
  </div>
</div>

Media objects do not have position: relativeby default, so we need to add the .position-relativehere to prevent the link from stretching outside the media object.

Media with stretched link

This is some placeholder content for the media object. It is intended to mimic what some real-world content would look like, and we're using it here to give the component a bit of body and size.

go somewhere

<div class="media position-relative">
  <img src="..." class="mr-3" alt="...">
  <div class="media-body">
    <h5 class="mt-0">Media with stretched link</h5>
    <p>This is some placeholder content for the media object. It is intended to mimic what some real-world content would look like, and we're using it here to give the component a bit of body and size.</p>
    <a href="#" class="stretched-link">Go somewhere</a>
  </div>
</div>

Columns are position: relativeby default, so clickable columns only require the .stretched-linkclass on a link. However, stretching a link over an entire .rowrequires .position-staticon the column and .position-relativeon the row.

Columns with stretched link

Another instance of placeholder content for this other custom component. It is intended to mimic what some real-world content would look like, and we're using it here to give the component a bit of body and size.

go somewhere

<div class="row no-gutters bg-light position-relative">
  <div class="col-md-6 mb-md-0 p-md-4">
    <img src="..." class="w-100" alt="...">
  </div>
  <div class="col-md-6 position-static p-4 pl-md-0">
    <h5 class="mt-0">Columns with stretched link</h5>
    <p>Another instance of placeholder content for this other custom component. It is intended to mimic what some real-world content would look like, and we're using it here to give the component a bit of body and size.</p>
    <a href="#" class="stretched-link">Go somewhere</a>
  </div>
</div>

Identifying the containing block

If the stretched link doesn't seem to work, the containing block will probably be the cause. The following CSS properties will make an element the containing block:

A positionvalue other thanstatic
A transformor perspectivevalue other thannone
A will-changevalue of transformorperspective
A filtervalue other than noneor a will-changevalue of filter(only works on Firefox)

Card with stretched links

Some quick example text to build on the card title and make up the bulk of the card's content.

Stretched link will not work here, because position: relativeis added to the link

This stretched link will only be spread over the p-tag, because a transform is applied to it.

<div class="card" style="width: 18rem;">
  <img src="..." class="card-img-top" alt="...">
  <div class="card-body">
    <h5 class="card-title">Card with stretched links</h5>
    <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>
    <p class="card-text">
      <a href="#" class="stretched-link text-danger" style="position: relative;">Stretched link will not work here, because <code>position: relative</code> is added to the link</a>
    </p>
    <p class="card-text bg-light" style="transform: rotate(0);">
      This <a href="#" class="text-warning stretched-link">stretched link</a> will only be spread over the <code>p</code>-tag, because a transform is applied to it.
    </p>
  </div>
</div>
