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. Please note given how CSS position
works, .stretched-link
cannot be mixed with most table elements.
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.
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: relative
by default, so we need to add the .position-relative
here 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="ml-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: 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.
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 pr-md-0">
<h5 class="mt-0">Columns with stretched link</h5>

<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
(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: relative
is 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.
