Hi Dmitry,

yes, on complex sites with many different DS this might not always work. 
But in my case I put all the CSS for any template in one CSS file, so it 
only has to be loaded once and get's cached by the browser.

actually I don't use hacks unless I really found no other solution for 
it - I don't like them either. As for the png transparency bug in IE. If 
you write the filter-stuff inside your regular CSS (which is possible 
without any doubt), then the W3C-CSS parser marks your css as invalid. 
Some might not care about that, but if you have customers that strictly 
wanna have valid documents, then you might exclude it from regular css. 
And that's where the conditional comments get involved. This 'nonvalid' 
css stuff simply is put to a seperate CSS file and only provided for IE.
And when I have a separate css for IE anyway, I also put every other css 
bugfix for IE into it, like probably correcting the 3px float bug or 
using other properties forcing to use different boxmodel handling or 
whatever, so that I don't have to use '* html onlyforIE' stuff.

As I wrote - in 99% I don't use hacks - I just need a conditional 
comment for some IE5 (yes, I still care about that) and IE6 fixes.
