Pure CSS – Normalize.css:
Normalize is CSS file developed by Nicolas Gallagher and Jonathan Neal for cross-browser consistency.
As we discussed, Normalize.css is base for Pure.CSS. But few HTML elements like tables, menus, forms will have regular styling. We can think that Pure will replace for such requirements. In order to use Normalize.css, below is the link element for the same which you have to place in the <head> tags before your webpage specific style sheet links.
<link rel="stylesheet" href="https://firstname.lastname@example.org/build/base-min.css">
