Adding the .stretched-link class to a link will make the containing block of the ::after pseudo element of the link clickable. In most cases, this means that an element with position: relative; which contains a link with the .stretched-link class is clickable.

Cards are relative by default, so in this case you can safely add the .stretched-link class to a link in the card.

{% capture example %}

{% include icons/placeholder.svg width="100%" height="180" class="card-img-top" text=" " title="Card image cap" %}

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

{% endcapture %} {% include example.html content=example %}

Media objects are not relative by default, we need to add the .position-relative here to prevent the link from stretching outside the media object.

{% capture example %}

{% include icons/placeholder.svg width="144" height="144" class="mr-3" text=" " title="Generic placeholder image" %}

Media with stretched link

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.

Go somewhere

{% endcapture %} {% include example.html content=example %}

Columns are relative by default, so if we want to stretch the link over a row, we need to add the .position-static class to column and add the .position-relative to the row.

{% capture example %}

{% include icons/placeholder.svg width="100%" height="200" class="w-100" text=" " title="Generic placeholder image" %}

Columns with stretched link

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.

Go somewhere

{% endcapture %} {% include example.html content=example %}

Multiple links can be added to elements with a stretched link, but their z-index must be increased to be become clickable.

{% capture example %}

{% include icons/placeholder.svg width="100%" height="180" class="card-img-top" text=" " title="Card image cap" %}

Card with multiple links

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

The whole card will be linked to this link

This link will be unclickable, because the previous link is stretched over this link

This link will be clickable because position: relative is added and the z-index is higher than the z-index of the ::after pseudo element of the stretched link

{% endcapture %} {% include example.html content=example %}

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)

{% capture example %}

{% include icons/placeholder.svg width="100%" height="180" class="card-img-top" text=" " title="Card image cap" %}

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.

{% endcapture %} {% include example.html content=example %}
