Pseudoelements
Pseudoelements are a means of adding content rather than style to an
element. They are enabled by placing a colon after an element type
specifier, followed by a pseudoelement. For example, to place some
text before an element that uses the class offer, you could use a rule such as
this:
.offer:before { content='Special Offer! '; }Now any element using the class offer will have the string supplied to the
content property displayed before it.
Likewise, you can use the :after
pseudoelement to place items after all links (for example), as with the
following, which will follow all links on a page with the link.gif image:
a:after { url(link.gif); }Become an O’Reilly member and get unlimited access to this title plus top books and audiobooks from O’Reilly and nearly 200 top publishers, thousands of courses curated by job role, 150+ live events each month,
