CSSWarp : A CSS3 Text to Path Generator

CSS3Warp is a proof of concept: create Illustrator like "warped" text (text following an irregular path) with pure CSS and HTML.
How does it work?

CSS3 brings new text-transform options: rotation, skew, matrix, transform-origin... By applying the right transformations to every single letter it is possible to create the illusion of text following a path.

Type your text into the webform, click "Warp it!", then alter the path as you like. You can attach your text to a circle or a bezier. Add or delete points, or change position, angle and radius of the circle. When your done, click "Generate code". Copy the CSS and HTML into your document.

Minimus: The OS X JavaScript and CSS Minifier

Users like fast websites. That’s one of the universal rules of web development. To attain faster speeds, it’s common to use a process known as “minification” to compress the file size of JavaScript and CSS. Yahoo developed one of the most commonly-used tools for this, a command line program called the YUI Compressor. This open source project has become integrated into many other tools, including numerous websites that will minify any JavaScript or CSS you paste into a form field.

Minimus is a GUI frontend for Yahoo’s YUI Compressor. Instead of using inconvenient and slow websites to compress your JavaScript and CSS, you can do it right on your Mac.

Add files to the queue by dropping them on the Dock icon (or by using the File menu) and press the Minify button to start the process. In no time at all, copies with a .min.js or .min.css extension will appear alongside the originals.

Minimus is a free download, but donations are appreciated by the author if you find the app useful.
Requires Mac OS X 10.6 Snow Leopard.

Speed Your Page With Easy CSS Sprite Generator

CSS sprites are a commonly used technique to decrease page load times.
This CSS technique can make your website load faster. Instead of having a dozen images that are included on every page of the site - your logo, RSS button, icons for social media links, etc. - you combine them all into one big image. You can then use CSS to display just the portion you need in any given spot.

Sprite Cow helps you get the background-position, width and height of sprites within a spritesheet as a nice bit of copyable css.

Automated spritesheet generators are pretty cool, but if you prefer the control over optimisation and compression you get by making them manually, then Sprite Cow provides you a user-friendly solution.
The web interface couldn't be easier. Upload your image and have a click around. It becomes pretty obvious. So you don't waste your time copying all the positions & sizes from graphics

About

The Ultimate CSS Gradient Editor was created by Alex Sirota (iosart). If you like this tool, check out ColorZilla for more advanced tools such as eyedroppers, color pickers, palette editors and website analyzers.

As you might know, HTML5 introduced many exciting features for Web developers. One of the features is the ability to specify gradients using pure CSS3, without having to create any images and use them as repeating backgrounds for gradient effects.

Important: You'll need a recent version of Firefox, Chrome, Safari or Opera to use this Gradient Generator. The resulting CSS gradients are cross-browser - they will work in these browsers and will also fall back to a simpler gradient in Internet Explorer.
