As other answers have explained, the CSS rule uses the
content
property to insert a character by its Unicode number.However, the character used is U+F107 PRIVATE USE CHARACTER-F107. This means that it has no meaning except by private agreements and should not be used in public information interchange. Unfortunately, some “awesome” tricks use Private Use code points to insert graphic symbols. This means that unless a very specific font, with some symbols assigned to those code points is used, a generic symbol of an unknown character appears.
So it is much safer to use an image instead, in the content proper.
CSS Content Property : The content property is used with the :before and :after pseudo-elements, to insert generated content.

CSS has a property called
content
. It can only be used with the pseudo elements:after
and:before
. It is written like a pseudo selector (with the colon), but it's called a pseudo element because it's not actually selecting anything that exists on the page but adding something new to the page.Font Awesome is a web font containing all the icons from the Twitter Bootstrap framework, and now many more.
You can find a list of
FontAwesome
here : A list of Font Awesome icons and their CSS content valuesYou can also go through this link, FontAwesome Examples, where you can see different icons and how to apply different size on it.
Using
content
property embeds a virtual content inside an element, it is used with a pseudo:before
or:after
, so if you use:before
, the content will be embedded before.From MDN :
Content property can hold any character, number, entities. For more information, you can refer an article here.
Also, you can get an handy converter here.
This method is also used by font-awesome - Example and other related svg font embedding libraries, where you can simply call classes to the elements and the fonts will be embedded virtually.
Also, just a side information, content generated using CSS
content
property isinline
by default, also this is rendered inside the element and not outside..It's an escaped unicode character.
