Requirements
  • This course takes a casual-yet-direct approach to learning LESS. We’ll talk through the features and then get hands-on building out some styles. You’ll learn by doing!
Description

CSS is great; it’s a staple of the web and it helps us to produce beautiful websites, but some parts of it are archaic, and it’s often time-consuming to get right. LESS changes that. LESS includes built-in features that allow you to speed up your development and make your stylesheets easier to produce.

Learning LESS will guide you through the basics of setting up LESS within your workflow. LESS is like CSS on steroids. This course will introduce you to the main features of the language and leave you with the know-how required to make your stylesheets more efficient and maintainable.

This course starts with the fundamentals and shows you how powerful LESS can be. We’ll start by introducing you to the language, followed by incorporating LESS into our workflow, including automation and taskrunners. You’ll learn what variables do and how to use them. You’ll then find out how to create maintainable CSS using mixins and extends, and you’ll discover the best way to organise your LESS code. We’ll look at the powerful built-in functions and finally examine the other ways to power up our front-end development workflow!

Learning LESS takes you from zero to hero, leaving you with the expertise required to produce efficient stylesheets.

Introduction to LESS
3 Lectures 07:05

This video provides you with an overview of the entire course.

Preview 01:42

The aim of this video is to describe what LESS is and what a CSS preprocessor does.

What Is LESS?
03:14

This highlights just how easy LESS is to work with if you already know CSS.

Woah! It's That Easy, Huh?

Getting LESS into Your Current Workflow
4 Lectures 22:25

The aim of this video is to show the viewer the easiest (but not necessarily the best) way to get up and running with LESS using the direct LESS.js file parser.

Preview 05:02

The aim of this video is to show the viewer how to set up a task runner such as Grunt to automate her processing.


Using a Task Runner
06:08

The aim of this video is to show the viewer how to use third-party software to process LESS files.

Using Third-party Software
08:17

We'll take a look at using your code editor to convert LESS on the fly.

Variables Can Make Our Lives Easier
4 Lectures 14:08

We will explain what variables are and how they work.

Preview 05:59

In this, we will take LESS variables beyond basic usage.

Advanced Variable Usage
02:35

Nesting our LESS selectors can help in organizing our code into useful chunks, and this video will look at the good and bad points of nesting.

Basics: Nesting
03:12

This video will show you how to keep our code organized and in order.

Mixins
6 Lectures 21:25

Mixins are an awesome feature of LESS, but it’s difficult to understand what they do.

Preview 03:37

Browsers can be a pain, especially with CSS3 selectors. Some browsers enable this functionality but behind a flag while the CSS specification is being finalized.

Using Mixins for Cross-browser Compatibility
04:17

The mixins we’ve written so far are fixed. If we wanted to change one of the values within our mixin, we could either write a new mixin or copy the code into our core LESS file, removing the mixins altogether. This video shows how to bring arguments into our mixins.

Parametric Mixins
03:15

We looked at a mixin that I’ve written. Now, you can start writing your own.

Writing Your Own Mixins
02:23

Sometimes, it may feel like a chore when you’re constantly including core classes within your HTML. LESS extends can help you avoid this.

Writing LESS Code with Extends
04:16

Our .less file may quickly become bloated with variables, mixins, extends, and functions.

A Final Word on Organization

Power Up Your Code with LESS Functions
4 Lectures 20:48

While building our color palette, we may want to have varying shades of our primary colors. We would want an easy way to adjust the colors.

Preview 03:46

This video covers more ways of manipulating color.

Advanced Color Functions
07:25

Oh no! We need to add padding to an element, but this value is the sum of two other values.

Math Functions
04:11

This video shows you some of the additional features of LESS.

Image Tools and Other Available Functions

Power Up Your Frontend Tool-kit
4 Lectures 16:57

Learn about automating repetitive tasks when developing websites.

Preview 03:59

Set up a prewritten set of LESS mixins.

LESS Prefixer
02:10

Writing code can sometimes be repetitive and laborious. Emmet fixes this.

So, we now know the basics of LESS and how to integrate LESS into our workflow, and we also have some new tools to help us out. So, where do we go from here?
