html - Override CSS Classes Infinitely -


this more of theoretical question.

is stack of overrides css ad-infinitum? instance, there css override every override?

lets have written this:

<!doctype html> <html lang="en">   <head>     <meta charset="utf-8">     <title>title</title>     <style>       .a {         color: red;       }       /* override again */       div.a {         color: blue;       }       /* again! */       body div.a {         color: yellow;       }       /* again!! :) */       html body div.a {         color: yellow;       }       /* , again!! */       html body div.a {         color: pink !important;       }     </style>   </head>   <body>     <div class="a">a</div>   </body> </html>

is !important combined html body div.a absolute highest level override div.a?
must there exist higher override?

in theory can repeat rule increase specificity.

.foo.foo.foo { }

in practise, browsers treat selector having many components , ignore it.

(there style attribute, more specific selector)

Sure, some authors could pull it off, but if you worked at an office, what were you supposed to do? Go to work with a bag over your head? But today anyone can accomplish this, because anyone can author a blog (and you thought I was going to tell you to work with a mask on, or something). Copyright Ovidiu Iordachi - Fotolia.com Depending on your motives, you may or may not have considered blogging anonymously.

These two ingenious programs have all but revolutionized the way advertising is done on the web. Warning: If you are thinking..."web advertising isn't for me, I just need a few more clients around the block"...you better read this or be prepared to have your competitors eat your lunch. Goolge AdSense - Again content is king at Google. This program allows web site "publishers" to add some code from Google and receive "content relevant" ads on their site from other site owners.
