CSS is basically Cascading Style Sheets. It defines how html elements are displayed. There are 3 ways to use CSS and they are the Internal style sheet, Inline styles and external style sheet. I will be talking about external style sheet as it is our focus. Its styles normally saved in "external.css files". This made it able to change appearance and layout of multiple pages all at once. It is located in the same folder as the html file. Each page link to .css file using link tag which goes inside head section. The difference between a CSS example without styles and with styles is that the one without styles has no colour while the one with styles has colour. The colour is useful as it attracts the readers' attention and this will let the readers not feel so bored.
