View gets CSS classes properties but not the IDs. Wierd :( !

[eluser]zrowcrypt[/eluser]
This one is totally new. I wrote a sub view(signup.php), included it in the main view(account.php) which is called by the main controller. Everything works fine. The CSS style of signup.php is in signup.css file.

The problem is when the view gets loaded, it takes the styles of the classes but bot those of the id elements from the css file.

Now, I absolutely had no idea that even such a problem can occur. Any idea guys?
