CSS rules have weight, and you should leverage those rules to correctly cascade styles.

element = 1 pt
class = 10 pt
id = 100 pt
inline = 1000 pt

An ID has a relatively high specificity of 100. A class has a specificity of 10.

#idname.classname - Now this selector has a specificity of 110.

The reason for not allowing html inside the content parameter is the fact that CSS is designed to work in a 
single pass-through of the page. If there were html, that would need to be styled, which means the css would
need to come back and process itself all over again to style that HTML after it was done styling everything else. 
This extra functionality would rarely be used by anyone but would still come with a speed cost to everyone
