Overview of this book

If you are a designer or developer who wants to quickly learn how to harness the power of Less.js to write more efficient CSS styles that can be applied to a website of any size, then this book is for you. This book will help you master both the basic functions and advanced features of Less.js. It would be helpful to have some familiarity of writing CSS styles, although no prior experience of using CSS preprocessors is required.

Using variables to calculate sizes


Now that we have chosen the fonts we want to use, we need to ensure that we can set the right size for the occasion; thankfully, Less has a number of techniques that we can use to create our CSS styles.

The simplest technique is to assign a font size to a set variable and then reference this variable throughout your code:

@font-size-base: 14px;

Once the initial variable is set, we can then create a range of font sizes automatically, by multiplying the base value with a graduated set of numbers:

@font-size-large: @font-size-base * 1.25;
@font-size-small: @font-size-base * 0.85;
@font-size-mini: @font-size-base * 0.75;

When compiled using a precompiler, Less will convert these into valid CSS font sizes as shown in this screenshot:

This is a very simple way of defining font sizes; if we need to change the font sizes, all we need to do is change the value of @font-size-base and Less will take care of updating the others automatically.
