# 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
html

    <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
html

    <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
html

    <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 `position` value other than `static`
- A `transform` or `perspective` value other than `none`
- A `will-change` value of `transform` or `perspective`
- A `filter` value other than `none` or a `will-change` value 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: relative` is added to the link

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

html

    <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>
