The possibility of embedding any font you like into websites via @font-face is an additional stylistic device which promises to abolish the monotony of the usual system fonts. 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. This quick introduction to @font-face will lead you towards a guide through the @font-face kit generator.
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.

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:
This entry is part 2 of 16 in the CSS3 Mastery Session - Show All « Previous Next » 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. So you learned the base id , class , and descendant selectors – and then called it a day? If so, you’re missing out on an enormous level of flexibility. While many of the selectors mentioned in this article are part of the CSS3 spec, and are, consequently, only available in modern browsers, you owe it to yourself to commit these to memory.
The clearfix hack is a popular way to contain floats without resorting to using presentational markup. This article presents an update to the clearfix method that further reduces the amount of CSS required. Demo: Micro clearfix hack Known support : Firefox 3.5+, Safari 4+, Chrome, Opera 9+, IE 6+ The “micro clearfix” method is suitable for modern browsers and builds upon Thierry Koblentz’s “clearfix reloaded” , which introduced the use of both the :before and :after pseudo-elements. Here is the updated code (I’ve used a shorter class name too):
