CSS Quick Guide

This is a quick guide for web developers where we have listed all the CSS properties defined in the World Wide Web Consortium's Recommended Specification for Cascading Style Sheets, Level 2

We include each property's possible values, defined as either an explicit keyword or as one of these values:

• angle: A numeric value followed by deg, grad or rad.
• color: Either a color name or hexadecimal RGB value, or an RGB triple of the form:rgb(red, green, blue)
• frequency: A numeric value followed by hz or khz, indicating Hertz or kiloHertz
• length: An optional sign (either + or -), immediately followed by a number (with or without a decimal point), immediately followed by a two-character unit identifier like px or pt or em etc.
• number: An optional sign, immediately followed by a number (with or without a decimal point).
• percent An optional sign, immediately followed by a number (with or without a decimal point), immediately followed by a percent sign.
• shape: A shape keyword, followed by a parentheses-enclosed list of comma-separated shape-specific parameters. Currently, the only supported shape keyword is rect, which expects four numeric parameters denoting the offsets of the top, right, bottom, and left edges of the rectangle.
• time: A numeric value followed by s or ms, designating a time in seconds or milliseconds.
• url: The keyword url, immediately followed (no spaces) by a left parenthesis, followed by a URL optionally enclosed in single or double quotes, followed by a matching right parenthesis. For example: url("http://www.tutorialspoint.com/")
