SASS CSSRuby engine compiler for CSSExtending the benefits of CSS by allowing nested rules, variables,mixins, selector inheritance, and more.http://sass-lang.com/Other equivalent processors: Javascript: LESS - http://lesscss.org/ CSS Authoring Framework: COMPASS - http://compass- style.org/

Pros & Cons of SASS Pros Cons•Uniform CSS •Reliance of a compiler•Abstraction of commonly used •Knowledge of Ruby language is CSS - mixins helpful•Ability to create functions •All or nothing•Variables •Disconnect between CSS and•Nesting SASS CSS in dev consoles

VariablesIn CSS we widely use common values for different element styles.For example, we use colors, width, height, etc... throughout our CSS styles.With variables, these common values can be declared once and re-used throughout thestylesheets.Example: $tableColor: #F3F1EB; $tableBorderColor: #EFEFEF; @mixin sortBg { background:$tableColor url(../img/bg.gif) no-repeat right center; &:hover { background-color: darken($tableColor, 25%); } }

MixinsMixins are a very potent asset of SASS.With mixins, the most commonly used CSS can be abstracted to a mixin and included asneeded.Example: @mixin handCursor { cursor: hand; cursor: pointer; }

Mixins - AdvancedMixins can become very advanced and can contain logic .Example - setting Linear Gradients - http://kiano.sh/IjEpZm

FunctionsFunctions allow for computation logic.Functions return values.Example:@function responsiveFontSize($fontSize: 16, $isIE: false) { @if $isIE { @return (($fontSize/16) - 0.02) + em; } @else { @return ($fontSize/16) + em; }}@function rfs($fontSize: 16, $isIE: false) { @return responsiveFontSize($fontSize, $isIE);}

SASS CSS BoilerplateLeveraging the CSS from HTML5 boilerplate, converted it to SASS equivalent.Divide the style.css file into the following modular sections: normalize.scss - http://kiano.sh/IBIrzU helper.scss style.scss functions partials
