How to insert a line break before an element using CSS

Question

I feel like I saw a way, using the CSS content property, to insert a line break tag before an element. Obviously this doesn't work:

#restart:before { content: '<br/>'; }

But how do you do this?

Answer 1

It's possible using the A escape sequence in the psuedo-element generated content. Read more in the CSS2 spec.

#restart:before { content: 'A'; }

You may also need to add white-space:pre; to #restart.

note: A denotes the end of a line.

p.s. Another treatment to be

:before { content: ' '; display: block; }
