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](https://www.w3.org/TR/CSS21/visuren.html#propdef-position), `.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.
