The feedback for the talk was quite good. Turned out better than I hoped. I just hope that the slides do make some sense without me talking alongside.
Hope it's going to be a success. Sadly I couldn't make it to this barcamp, I hope to be there next time.
Yet there's a thing I wanted to point out: Your CSS Zen Garden example does violate DRY, but it's not well written either. Those declarations can be done otherwise, like assigning the block of code to h1 itself, and then declaring the background image for the specific ID.
This way, you sometimes have to put multiple, successive declarations for one element, but I seldomly find myself writing a block of attributes twice. The power I see in .LESS here is avoiding to write selectors like: #ID > #otherID >.class.class > e
Cause you mostly can DRY when using plain CSS, except for the selectors.
Actually this was a made up sample since I did not find any sufficiently bad enough code in CSS Zen garden.
The headline may have been misleading, but I meant it as the “CSS Zen garden approach” not that actual code from CSS Zen garden was harmed.
The main point of the sample was to illustrate a simple usage szenario that is also understandable to non-css gods.
Also, the main point of the sample was that there are ample szenarios where DRY is violated when using straight CSS. (http://www.kaernten.at comes to mind here).
Well on this site, the main concern is the massive use of classes in the HTML markup. There are better ways to solve this problem, but as many people are working on the markup and stuff has to be added continously, it would be a rather tedious task to redo the CSS in a better way – well, you know the story. .LESS would have been pretty handy here
