Cascading Style Sheets, CSS, is a very important tool in the world of Web sites. I am just beginning to study this tool. What is it exactly? It is style sheets that cascade! What does that mean, you ask? Have I told you that you ask very good questions? You do.

CSS is a text file that has various settings in it to style a Web page. That means you can set fonts, colors, headings, spaces and all sorts of settings in order to make a page or an entire site to look uniform. That is where the cascading part comes in.

Once a CSS is setup, all the Web master has to do is make a change to the style sheet itself and that change cascades throughout the page or site. Say you have a page of text and it has five sections. Each section has a heading. Say that heading is set at H1. H1 is a font size which is fairly large. Let’s say you decide the headings should be H3, several sizes smaller. Without CSS, you need to highlight each heading, change the font size, rinse, repeat four more times.

Here is the magic of CSS. If you have a style sheet set up, edit the sheet to change the headings from H1 to H3. One change, that’s it! POOF! Your headings are all H3 once the sheet is applied to the page or site. Now you begin to understand the power of CSS. Let me know what else you would like to see me write about.
