jQuery Simple Equal Heights

Version 1.5.3

Summary

Simple jQuery plugin to equalize heights of multiple elements on a page.

Author

Usage

Include jquery.equalheights.min.js after calling jQuery in the footer. Alternatively, include in your plugins.js file if using HTML5 Boilerplate.

Alternatively, install with bower:

bower install jquery.equalheights

Auto Initialize

Add data-equal="MYELEMENTS" to the parent container, where MYELEMENTS is div, section, li, whatever you'd like. See the example for more information. You can specify options by setting them as a data-attribute, for example: data-watch="true".

Manually Initialize

$('.yourelements').equalHeights([options]);

Select whatever elements need equal height. You can optionally pass in an object with one or more options

Option: wait

If you pass in {wait: true} your elements' height will only be equalized as soon as they have layout.

$('.yourelements').equalHeights({wait: true});

Option: watch

Pass in {watch: true} if you want to execute equalHeights on resize. This can improve the responsiveness of the elements with equalized heights.

$('.yourelements').equalHeights({watch: true});

Option: unwatch

Pass in {unwatch: true} to unwatch a set of elements that are currently watched.

$('.yourelements').equalHeights({unwatch: true});

Caveats

If using @font-face or Google Web Fonts, you may need to wrap the function call in a setTimeout for 100ms-200ms or call it on window load (jQuery.height() needs to fire after the font is rendered to properly calculate the height). Otherwise even the wait option could fail here as the element might be rendered and have layout before the fonts are loaded and applied.

Requirements/Browsers

Tested with jQuery 1.7.x.

Works in IE6+, Chrome 14+, Safari 4+, Firefox 3.0+, Opera 10+.

Examples

See example.html in examples folder.
