===== CSS Cheat Sheet ===== This is a summarized form of the [[http://www.w3schools.com/css/default.asp | CSS Tutorial]]. For reference this is the [[http://www.w3.org/TR/REC-CSS2/ | CSS2 Specification]] . ==== What is CSS ==== * CSS stands for Cascading Style Sheets. * Styles define how to display HTML elements. Style sheets are collections of styles. * Multiple style sheets will cascade into a single style definition. * There are 3 ways to specify styles (decreasing priority): - inline as an element style attribute

- in an external style sheet in a css file ==== CSS Syntax==== CSS syntax is made up of three parts - selector {property: value}. * Multiple property-value pairs may be separated by semi-colons. * Multiple selectors must be separated by commas * Values must be quoted if they are multiple words * A simple example h1,h2,h3 { text-align: center; color: black; font-family: "sans serif" } * Classes allow groups of elements to share formatting e.g. p.right {text-align: right} .blue {color: blue}

right-aligned blue text

* Styles can also match on attribute values or id e.g.


input[type="text"] {background-color: blue}
#id {background-color: blue}
p#id {background-color: blue}

* CSS uses C-style comments - /* comment */ . ==== CSS Properties ==== * Background properties examples
