CSS Utility Classes

A collection of CSS utility classes - based on Emmet shorthand conventions - to aid in object-oriented CSS development.

Usage

Terse OOCSS classes can be a powerful tool for rapid and scalable development. They can be used independently, or to augment existing objects.

<div class="card">
	<div class="card__photo ta-c">
		<h3>Business Name</h3>
		<div class="fz-s">Some City, America</div>
	</div>
	<div class="card__cell">
		<h3 class="mt-xs mb-xxs">John Doe</h3>
		<div class="fz-s"><span class="fw-b">Member number:</span> 081425</div>
		<div class="mt mb-l">
			123 Main St.<br />
			Columbus, OH 43215
		</div>
		<a href="#" class="button">Select Account</a>
	</div>
</div>

Install

You can download the repo, or install via Bower:

*values derived from golden ratio

Examples:
