It surely would be all too easy if there was only one Web font format out there. Instead, there’s quite a variety, as you will get to know in this article.
Advertisement If you’ve been keeping tabs on various Web design blogs, you’ve probably noticed that the :before and :after pseudo-elements have been getting quite a bit of attention in the front-end development scene — and for good reason. In particular, the experiments of one blogger — namely, London-based developer Nicolas Gallagher — have given pseudo-elements quite a bit of exposure of late.
I’ve been using LESS religiously ever since I stumbled upon it months ago. CSS was never really a problem for me, in and of itself, but I was intrigued by the idea of using variables to create something along the lines of a color palette for my websites and themes.

The “Don’t use IDs in selectors” suggestion seems to have offended Matt the most, but I was surprised that many commenters also mentioned this as being a reason to avoid CSS Lint. This surprised me because smart people have been saying prefer classes to IDs for a while now. The article was light on reasons why this suggestion might be bad, but it boils down to:
Twice a month, we revisit some of our readers’ favorite posts from throughout the history of Nettuts+. This tutorial was first published in November, 2010.

Because future matters, we designers need to rely on modern browsers. Internet Explorer 7 was released by Microsoft in October 2006, five years after the Long Sleep of IE6 . Although it fixed a number of bugs of its predecessor and improved web standards compliance, it still does not support CSS2 (specification since 1998 ), neither Acid2 test .
