Cascading Style Sheets or CSS, for short, is a tool to add styles and layout to our HTML web pages. It saves us a lot of time and it also enables us to seperate the style definitions from the HTML file(s).

CSS is a style language that defines layout and styles for our HTML documents. We can use CSS to control fonts, colors, margins, lines, height, width, background images, etc. CSS is supported by almost all web browsers today.

CSS vs HTML

HTML is used to structure content, whle CSS is used for formatting structured content.

Back in time HTML was originaly invented to add structure to text. An author could mark his text by stating "this is a heading" or "this is a paragraph" using HTML tags such as <h1> and <p>. As the time passed and the web gained popularity, designers, like you, started looking for possibilities to add formatting, styles and layout to HTML documents. To meet this demand, the browsers started to support new HTML tags such as <font>.

The resultant HTML started to become messy in casses. CSS was invented to remedy this situation. CSS provides us sophisticated layout and styling opportunities that are supported by almost all web browsers. CSS also allows to seperate the layout and styling information from the content of the HTML documents making maintenance a lot easier.

CSS is very easy and fun to learn. We do not need any special software to learn CSS, only a simple text editor like note pad and a web browser are enough.
