[TYPO3] Indentation problem in typo3 4.2.1

[Fearless Goblin (Victor Livakovsky)]

Also sometimes CSS-styles won't work, if you have not specified the
inlaid level for them.
F.e. we have such structure:
<div id="header">
     <div class="subheader">
          <div id="header_menu">
               <ul>
                     <li class="active">Item1</li>
                     <li>Item2</li>
                     <li>Item2</li>
               </ul>
          </div>
     </div>
</div>

and when I specified something like this:
.active {
        color: red;
}
it didn't worked!

But, f.e., this:
#header_menu ul li.active {
             color: red;
}
worked fine!

I don't know why it's so, but the fact still remains.

Maybe it'll help.
