Links/Buttons
Turn callout blocks with a link into a button
This snippet will only affect callout blocks with one line of text that is a link. It will make the link fill the width and height of the callout turning it into a button so the entire block is clickable rather than just the text.
/* Turn a single line callout block into a button (Entire block is clickable) */
.notion-callout {
position: relative!important;
}
.notion-callout .notion-callout__content .notion-semantic-string span .notion-link {
position: absolute!important;
height: 100%!important;
width: 100%!important;
top: 0!important;
left: 0!important;
right: 0!important;
bottom: 0!important;
padding: 15px!important;
padding-left: 50px!important;
border: none!important;
}
