Use Stylesheets
Akopọ
If HTML decides what is on a page, CSS decides how it looks. Cascading Style Sheets let you set the fonts, colours, spacing and alignment of your elements, and the clever part is the word cascading: when several styles could apply to the same element, clear rules decide which one wins. Write your styles once in an external file and you can give a whole website a consistent, professional look from a single place.
In this lesson you will learn the three ways to apply CSS (inline, internal and external) and the order of precedence between them, the syntax of a CSS rule with its selector and declarations, how to target elements, classes and ids, and the properties for fonts, colour, alignment and backgrounds. You will also see why external stylesheets must be linked with relative file paths.
