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>Most custom components do not have position: relative by default, so we need to add the .position-relative here to prevent the link from stretching outside the parent element.
Custom component with stretched link
This is some placeholder content for the 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="d-flex position-relative">
<img src="..." class="flex-shrink-0 me-3" alt="...">
<div>
<h5 class="mt-0">Custom component with stretched link</h5>
<p>This is some placeholder content for the 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>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 g-0 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 p-4 ps-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
transformorperspectivevalue other thannone - A
will-changevalue oftransformorperspective - A
filtervalue other thannoneor awill-changevalue 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.
