What is CSS ?

CSS, the design

CSS , stand for "Cascading Style Sheets". It was created in 1996, to complete HTML. The role of CSS is to manage the appearance of the web page (layout, positioning, decoration, colors, text size, etc.)

How does it work ?

CSS complete HTML, it means that for each elements in the HTML page, it's possible to add properties to style this elements. Properties can be color, background, font size or even display. If I choose the tag "<h1>", I can add the property "color: blue;", wich means that the text of all the h1 title will be blue. Look at the exemple below.
