I was looking at a class of a Wordpress template and saw that it created an image of a facebook logo using CSS content with a string of characters.
The snippet that generates the image is as follows:
.cmsms-icon-facebook-circled-1:before { content: '\ee2e'; }
I did not find anything in Google that explained to me how this is done, because by F12 I can not find the image.
The template link is:
These are the social network icons in the footer.
I was curious to know what it was about, because I saw that content can include an image using "content: url()"
