UCSSM is a CSS framework and a methodology for developing responsive, mobile first projects on the web.

Unlike other similar projects such as Bootstrap or BEM, UCSSM focuses on the utilitarian philosophy of CSS: which advocates using atomized classes with individual utility applied to the element instead of creating an initial set of predefined structures, styles and effects, thus increasing the overall size of the CSS file and the time it takes to maintain it or resume development.

Websites and apps that were made with UCSSM have generally offered higher performance results: the painting speed will be reduced by half or more than that; the rendering time will be around 400% faster and the size of CSS files will remain smaller and easy to maintain.

Installation

1. Clone this repo on your /stylesheet/ folder.
2. Create a new file as a main .scss, ex. styles.scss.
3. Append .scss to the template files: config_css, config_normalizer and config_vars.
4. Open your main styles.scss and @import each template.

The correct order in your styles.scss must be:

Usage

You can read an introductory article about the Utilitarian CSS Methodology to learn how to build with this new approach.

Once you have imported all the files into your main styles.scss you can open config_css.scss in order to start activating all the CSS properties you need for your project. You can start with the basic one, display, by searching the variable $config-display and change its value to true:

The next step is to open $config_vars.scss and search for $displays. Uncomment some values:

Refresh your website and open the compiled version of styles.css it must compile:

Now you can add this classes to your project:

You can comment/uncomment any map value and Compass will compile automatically the CSS for you on the next build making easy to check which properties are you supporting for your projects.

You can add new values to any map, for the case of $colors, $margins, etc.

By doing this, your CSS output will be really strict and you will only dispose those properties that you need.

The grid system

This framework let you use all the power of CSS-Grid. On config_vars you can find the $columns: variable with the amount of columns your grid must support. If you change this number, it means you compile as much grid-template-columns--[NUMBER] as this variable needs.
