Cross-browser stylesheet creation and css rule creation/deletion (includes IE6 support).

This was created to be a well-tested cross-browser library for basic CSS stylesheet and rule creaton/deletion.

browser support

Getting Started

css-controls is available via the following:

For npm and component, you can load it in as follows:

var cssControls = require('css-controls');

For bower and http, you can use vanilla JS

<script src="components/css-controls.js"></script>
window.cssControls; // `css-controls` is defined on `window` in camelCase

or you can use AMD

require(['css-controls'], funtion (cssControls) { /* code */ });

or CommonJS syntax (see npm/component section).

Once you have the module loaded, you can create new style sheets and add/remove CSS rules.

// Create a stylesheet (auto-appended to DOM)
var sheet = cssControls.createStyleSheet();

// Color all `p` tags red (ruleIndex = index rule was created at)
var ruleIndex = cssControls.addRule(sheet, 'p', 'color: red');

// Color the `body` green
cssControls.addRule(sheet, 'body', 'background: #BADA55');

// Remove the first rule
cssControls.removeRule(ruleIndex); // Equivalent to cssControls.removeRule(sheet, 0);

Documentation

css-controls returns 3 cross-browser functions.

cssControls.createStyleSheet();
/**
 * Create and append stylesheet to DOM
 * @returns {CSSStyleElement} Created stylesheet
 */
cssControls.addRule(styleSheet, selector, property);
/**
 * Add a CSS rule to a stylesheet
 * @param {CSSStyleElement} styleSheet Stylesheet to add rule to
 * @param {String} selector CSS selector (e.g. `.nav > .nav-bar`)
 * @param {String} property CSS property to apply to `selector` (e.g. `background: blue`)
 * @returns {Number} Index the rule was inserted at
 */
cssControls.removeRule(styleSheet, index);
/**
 * Remove a CSS rule from a stylesheet
 * @param {CSSStyleElement} styleSheet Stylesheet to remove rule from
 * @param {Numer} index Index of the rule to remove
 */

A large amount of the background knowledge came from quirksmode.

Examples

css-controls can be used with document.styleSheets as these are CSSStyleElements

// Color the `body` via the first stylesheet
var sheet = document.styleSheets[0];
cssControls.addRule(sheet, 'body', 'background: papayawhip');

Contributing

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint via grunt and test via npm test.
