Stretched Link
Make any HTML element or Bootstrap component clickable by “stretching” a nested link via CSS.
Stretched link on BootstrapExample
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.
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.
