Stretched link
Make any HTML element or Bootstrap component clickable by “stretching” a nested link via CSS.
Add .stretched-link
to a link to make its containing block clickable via a ::after
pseudo element. In most cases, this means that an element with position: relative;
that contains a link with the .stretched-link
class is clickable.
Cards have position: relative
by default in Bootstrap, so in this case you can safely add the .stretched-link
class to a link in the card without any other HTML changes.
Multiple links and tap targets are not recommended with stretched links. However, some position
and z-index
styles can help should this be required.
<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: relative
by default, so we need to add the .position-relative
here to prevent the link from stretching outside the media object.
<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>Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.</p>
<a href="#" class="stretched-link">Go somewhere</a>
</div>
</div>
Columns are position: relative
by default, so clickable columns only require the .stretched-link
class on a link. However, stretching a link over an entire .row
requires .position-static
on the column and .position-relative
on the row.
<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>Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.</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
position
value other thanstatic
- A
transform
orperspective
value other thannone
- A
will-change
value oftransform
orperspective
- A
filter
value other thannone
or awill-change
value offilter

<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.
