Exactly -- that's kinda the whole point of the 'cascading' part of Cascading Style Sheets.
It's why when I see nonsense like this:
<div id="header" class="clearfix">
<a href="http://http://somedamnedsite.turdpress.com/">Some Damned Site</a>
<h1>A Turdpress Blog</h1>
<ul class="menu" id="menu">
<li class="page_item"><a href="http://somedamnedsite.turdpress.com/">HOME</a></li>
<li class="page_item page-item-2"><a href="http://http://somedamnedsite.turdpress.com/about/" title="About">About</a></li>
</div><!-- #header end -->
(and yes the original turdpress skin I'm basing that on DOES the double http:// too) I wonder just what the **** the developer was smoking with that garbage. Especially since for 99.9% of the appearances that said markup is used for doesn't need anything more than:
Some Damned Site<br />
<small>A Turdpress Blog</small>
<li class="last"><a href="/about">About</a></li>
MORE than enough hooks to apply all the same styling as the original.
Spot on. I've rarely if ever seen the people who do the slap it all on one line routine not make the mistake of decaring the same property twice, and it's no wonder; it's such an illegible mess you can't even tell half the time where one property begins and the next ends - made even WORSE when they go and cram spaces everywhere EXCEPT between properties.
You make one property per line, tab them in, clear as a bell. You get a nice list of what properties are declared you can quickly go over.
Makes me wonder if the people who do shove it all on one line are on some crappy editor or undersized display that can't show more than 10 lines at a time or something... but then I'm spoiled as I find it hard to even think about coding on anything that won't show me at least 50 lines at a time anymore.
Basically, a lot of times it's just sloppy coding habits and sleazing it out any old way that cause the REAL headaches for developers -- and they are so blind to their own bad habits being the core of their issues... but then I learned high level languages from a Nun with a ruler. THWACK INDENT!!! THWACK DE-INDENT!!!
I really think a lot of programmers need a firm hand with a paddle when it comes to things like that.
