Course Description

This course will take you through all the essential tools to begin writing better CSS with LESS.

We will begin with the basics of LESS, highlighting all the key features in easy-to-follow, step-by-step chunks, ending with some existing scenarios where LESS could be beneficial and additional publications to further your education.

Then we will cover variables, LESS' way of storing repetitive data such as color values, font sizes, and more using customized names. After this, we will take a look at mixins, a CSS type function in LESS that, among other things, will greatly simplify the use of CSS3. In nesting, we will discuss how to write shorter, cleaner CSS. Finally, we’ll cover various functions and operations available within LESS that will allow you to further simplify your CSS and perform some really impressive actions you thought you’d never be able to do!

Rapid LESS will take you through LESS in a step-by-step way, so that you not only know how to write smart code, but why it’s a beneficial addition to your existing workflow.

This may be better for theme or template developers who need to be able to quickly and easily develop multiple iterations of sites and styles in various colors.


Working with color functions such as darken to perform minor adjustments to colors. Colors that are very well suited to subtle changes that occur in an end users web experience.


Discuss some of the more advanced LESS functions to highlight some of the great potential available to a developer when using LESS.

Section 6: Wrapping Up LESS

Numerous stylesheets impact on performance through numerous DNS requests and in turn impact on SEO. LESS is a great tool for mitigating this with its variation in the @import function.


The compiled versions of a framework can often contain styling and elements that are simply not needed for a specific site. Working with the LESS source files allows you to easily tailor make your own version of that framework to match a project's specific needs.
