Working With Jeet: an Alternative Responsive Framework Jeet is a lightweight, responsive framework which gets away from presentational classes, instead focusing on markup, style and semantics. Let me illustrate how Jeet compares to more common framework alternatives (Bootstrap, for example), we'll go over the download and setup procedure, then cover some of its main features. Lastly, we'll demonstrate Jeet in a working environment by rebuilding a responsive prototype of Webdesigntuts+. This is a hefty video, so grab a coffee and let's begin!

Getting started | Less.js CorySimmons/jeet jQuery UI Sass Reference Syntax There are two syntaxes available for Sass. The first, known as SCSS (Sassy CSS) and used throughout this reference, is an extension of the syntax of CSS3. This means that every valid CSS3 stylesheet is a valid SCSS file with the same meaning. The second and older syntax, known as the indented syntax (or sometimes just “Sass”), provides a more concise way of writing CSS. Either syntax can import files written in the other. $ sass-convert style.sass style.scss $ sass-convert style.scss style.sass Note that this command does not generate CSS files. Using Sass Sass can be used in three ways: as a command-line tool, as a standalone Ruby module, and as a plugin for any Rack-enabled framework, including Ruby on Rails and Merb. gem install sass If you’re using Windows, you may need to install Ruby first. To run Sass from the command line, just use sass input.scss output.css You can also tell Sass to watch the file and update the CSS every time the Sass file changes: Rack/Rails/Merb Plugin :style
Fluidity - A Modern CSS3 & HTML5 Framework for Node.js & Stylus 11 Mixin Libraries For Sass Designers Should Get If you use Sass in your development workflow, you know the importance of mixins.

Article Continues Below A building’s foundation defines its footprint, which defines its frame, which shapes the facade. Each phase of the architectural process is more immutable, more unchanging than the last. Working on the web, however, is a wholly different matter. But the landscape is shifting, perhaps more quickly than we might like. In recent years, I’ve been meeting with more companies that request “an iPhone website” as part of their project. A flexible foundation#section1 Let’s consider an example design. But no design, fixed or fluid, scales seamlessly beyond the context for which it was originally intended. Becoming responsive#section2 Recently, an emergent discipline called “ responsive architecture .
Fitts's law Fitts's law (often cited as Fitts' law) is a model of human movement primarily used in human–computer interaction and ergonomics that predicts that the time required to rapidly move to a target area is a function of the distance to the target and the size of the target. Fitts's law is used to model the act of pointing, either by physically touching an object with a hand or finger, or virtually, by pointing to an object on a computer monitor using a pointing device. It was proposed by Paul Fitts in 1954. Model[edit] Fitts's law has been formulated mathematically in several different ways. where: T is the average time taken to complete the movement. From the equation, we see a speed–accuracy trade off associated with pointing, whereby targets that are smaller and/or further away require more time to acquire. Success and implications[edit] Fitts's law is an unusually successful and well-studied model. In its original and strictest form: Mathematical details[edit] where Derivation[edit] Notes[edit]
