Baseline.js

Baseline.js is a simple jQuery plugin for restoring baselines thrown off by odd image sizes.

Simply call the plugin like so, passing the height of your baseline as a variable. It even works on responsive designs!

$('img').baseline(24); // Apply a 24px baseline to all images on the page
$('.content img').baseline(30); // Apply a 30px baseline to all images inside .content

You can also define multiple baselines for different breakpoints. Perfect for responsive design!

$('.content img').baseline({'0px':24, '700px':30}); // Apply a 24px baseline for all widths, 30px for widths above 700px

Vanilla JS

There's also a vanilla JS version available, so there's no need to load jQuery. Simply include baseline.js in your page, and call it like so:

baseline.init('img', 24); // Apply a 24px baseline to all images on the page
baseline.init('.content img', 30); // Apply a 30px baseline to all images inside .content
baseline.init('.content img', {0:24, 700:30}); // Apply a 24px baseline for all widths, 30px for widths above 700px

Thanks to Ben Howdle for the vanilla JS version. You rock, Ben.
