 We have explained how the fluid grid works under the hood, but calculating percentages is not the most exciting job for software developers.  The good news is that several responsive frameworks offer CSS, typography, and some JavaScript to jump-start UI development of a web application. They'll spare you from most of the mundane work with cascading style sheets.((("responsive web design (RWD)", "fluid grids", "frameworks supporting"))) Here are some of them:

-TIP: People who work with CSS a lot use an authoring framework called http://compass-style.org[Compass] with the CSS extension http://sass-lang.com/[SASS] or the CSS preprocessor http://lesscss.org/[LESS]. These systems compile to CSS, allowing code to include variables for tracking and calculating numbers such as column width and more. You can now modularize your CSS as well as your code. In <<sencha_touch>> we use a SASS theme that comes with the Sencha Touch framework.((("fluid grids", "frameworks supporting")))(((Compass CSS authoring framework)))

 Another technique is to use a content delivery network (CDN) that caches and serves images of different sizes for different user agents. The very first time that a request is made from a device with an unknown user engine, this first  "unlucky" user will get an image with a low resolution, and then the application makes an Ajax call, passing the exact screen parameters for this device. The CDN server resizes the original high-resolution image for this particular user agent, and caches it, so any other users having the same device will get a perfectly sized image from the get-go.((("content delivery network (CDN)")))
