Add stretched attribute 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 attribute is clickable.
Please note given how CSS position works, stretched attribute 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 attribute 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.
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<template>
<b-div flex>
<b-img
src="https://dummyimage.com/144x144/868e96/868e96"
flex-shrink="0"
margin="e-3"
alt="Generic placeholder image"
/>
<b-div position="relative">
<CardTitle>
<b-h
level="5"
margin="t-0"

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 link
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.
