CSS is almost certainly one of the best developments in web design since the first graphical web browsers were adopted on a wide scale. Where tables created clunky, slow-loading pages, CSS created much more streamlined and usable web pages. Plus, CSS has allowed designers to achieve a number of different styles that used to only be possible with images.
One of the best parts of CSS is that it's so simple once you know the basics. Where tables used to make incredibly complex and sometimes impossible-to-decipher code, CSS keeps things clean and simple. Add a few comments to keep everything organized and it becomes an absolute dream to work with.
Below are 50 fresh CSS tricks, techniques and tutorials that will help you to improve the quality of your next web design. Be sure to check out our previous article: 53 CSS-Techniques You Couldn't Live Without.
1. Security and Performance
While CSS is often thought of as merely a styling language, there are ways you can use it to add security to your site. There are also ways you can optimize your CSS to improve page load times. Both are discussed below.
Make your pages load faster by combining and compressing javascript and css files
This tutorial shows you how to create a PHP script to compress and combine multiple CSS and/or JavaScript files with gzip when they're called for by a browser. It speeds up the page load times while making it possible to still edit the individual CSS or JavaScript files without having to combine and re-compress everything each times.
Informal testing showed that a group of JavaScript files were reduced from 168Kb (and 1905 ms to transfer) to 37Kb (and 400 ms). There wasn't any data available for the effect it had on CSS files, but I'd guess it's probably pretty similar.
The Definitive Post on Gzipping Your CSS
This post covers the best and most recent methods for using GZIP to compress your CSS. It currently covers two different methods, both equally effective. One involves adding a bit of PHP to your CSS file (and renaming the file with a PHP extension instead of CSS) while the other method involves using the same PHP code with some additions but in a separate file.
Clickjane.css: A CSS User Style Sheet to Help Detect and Avoid Clickjacking Attacks
This post covers how to use clickjane.css to prevent clickjacking, a class of security vulnerabilities kind of like phishing scams and more formally referred to as user interface redressing. It's cross-browser compatible but, admittedly, probably only covers a small range of potential clickjacking vulnerabilities. It's still a good place to start, though.
5 Step Style Sheet Weight Loss Program
This post shows five different ways to trim the size of your style sheets. Techniques range from learning how to group selectors to using CSS shorthand. Each technique is thoroughly explained and includes related resources.

Fluid Images
Fluid layouts are great. They generally look and function just fine until you start introducing fixed-width elements within them—like images. This post shows how to make your images fluid, too. And it works for most embedded video. And while the basic technique includes just one CSS property, there is a workaround necessary to make it work on Windows machines.
Flexible Equal Height Columns

Creating a Polaroid Photo Viewer with CSS3 and jQuery
The photo gallery created with this technique is absolutely awesome. The HTML and CSS aren't super-complicated, and everything is explained really well.

Smart Columns with CSS and jQuery
This tutorial shows how to create smart columns inside liquid layouts using a combination of CSS and jQuery. Basically, it fits as many columns into the base column size as possible and then distributes any leftover white space among the columns there.

CSS Hack for Chrome, Safari and Internet Explorer
