7.3. CSS Techniques

In this section we are going to talk about some well-known CSS techniques (reset CSS files, text formatting, and the box model) and see how the different browsers react to these features.

7.3.1. Reset CSS Files

It is very common in desktop web design to create a CSS hack to reset all the default margins and padding for common HTML elements. We can use this technique when developing for the mobile web, with some considerations: we should only reset the elements we are going to use, we should avoid the usage of the global selector (*) for performance purposes, and if we are using an external reset CSS file we should consider merging it with our local CSS file.
