Have you ever tried reading a printed out website, then instantly becoming frustrated when you're trying to click the links? Pseudo elements can't really help you much with this, however they might help you a bit by displaying the links' urls! How do you do this, you ask? Let me show you the power of pseudo elements and the attr() function.
Printed documents only have two dimensions, and they aren't even clickable?! How can we tell the user what the underlined text goes to?
By using the content property together with the attr() CSS function, we can display the value of any attribute. As href is an attribute on a elements, surely we can display this too, right? Of course!
<a href="https://dev.to">a link with no clear sign of where it points to</a>
@media print {
a::after {
content: ' (' attr(href) ') ';
}
}
This code will yield the following result:
Granted printed documents have become rare, this is still a neat trick for those of us working with article heavy sites!

If you don't want to anchor links to display their destination, and you only want to write out the URLs and e-mail addresses you can change it to this:
That's a really nice suggestion, thanks!
