Hudson Continuous Integration CSS Sprites: What They Are, Why They're Cool, and How To Use Them By Chris Coyier On This article has been revised and re-written several times since its very first publication in 2007, to keep the information current. The most recent revision was done by Flip Stewart in January 2015. #What are CSS Sprites? Spoiler alert: they aren't fairies that write your stylesheets for you. To summarize: the term "sprites" comes from a technique in computer graphics, most often used in video games. CSS Sprites is pretty much the exact same theory: get the image once, and shift it around and only display parts of it. #Why use CSS Sprites? It may seem counterintuitive to cram smaller images into a larger image. Let's look at some numbers on an actual example: That adds up to a total of 14.38KB to load the three images. While the total image size (sometimes) goes up with sprites, several images are loaded with a single HTTP request. Thus, sprites are important for the same reasons that minifying and concatinating CSS and JavaScript are important. $ npm install sprity -g
Kotlin Programming Language SpriteMe jReject - jQuery Plugin for Simple Browser Rejection Grunt: Automated Testing With a look into our evolving JavaScript testing methods, Patrick shares how we're using Mocha, Jasmine, and Grunt. Introduction A few months ago we posted about our new build process, and we mentioned starting to use Grunt for the “freedom and customization” that it provided. Recently, Rob Tarr released a new application called Stuntman. Grunt to the Rescue Running both server and client-side JavaScript specs was an issue. Our solution: Test client side JavaScript with Jasmine Test our server side JavaScript with Mocha Not very challenging to do thanks to Grunt, but there are some important packages you will need. Prerequisites Grunt Setup Check out the example repository. Our basic setup consists of the following packages in our package.json file: Example “package.json” Gruntfile.js Setup Once you have your package.json and Gruntfile.js in a directory, install the packages with the following command (in your project directory): npm install Directory Structure Example Tests Client Server Running Tests
