UCSS

UCSS (or Utility  CSS) is just like a CSS framework, only instead of pre-built HTML&CSS widgets, this tool only features a list of classes.

Developers can take these classes, add them to desired HTML tags and easily append the class' properties to that element.

Basically if you need red text on a white background with a justify alignment you'll just need to add three CSS classes to the text block you want these properties to apply. Like:
<p class="ucss-text-align--justify ucss-color--red ucss-background-color--white">the text goes here</p>

A pretty simple concept, which basically lets you work more in the HTML file rather than the CSS file.

Some of the properties that these utility classes affect are:
- background
- border
- outline
- color
- text
- font
- margin
- padding
- list
- table
- box size
- visual formatting
- generated content

If the ones that you're looking for aren't in here, then feel free to add them to the UCSS source.
