Introduction to CSS |
Imagine coding an HTML page with several tables, each of the table attributes and content will have different display requirements. This means using a lot of tag attributes in your code and some of it may even get repetitive. While this has no impact on the human eye reading the page, search engine bots trying to index your content will be bogged by too much code before they even get to your page content. Plus, less code will enable your pages to load faster. Just to give you an idea of how things work, if we were to create HTML bold text for each of our pages, with the following properties: color: brown size : 12 font: Arial font style : italic bacground : yellow we would then have to use the following tag on every page: <b bgcolor='yellow'><i><font size="12" color="brown">Bold Text</font></i></b> to produce text like this: Bold Text This means every time you want to create bold text like this you will have to repeat the code above. With CSS, you could define these properties in one location and each of your pages can link to that page and use these properties as follows: first create your CSS code file as follows: b {save you file as stylesheet.css in the section of each of your HTML files include this: <link href="style.css" rel="stylesheet" type="text/css"> Then all you have to do in your HTML body is simply use the bold tag and it should pick up the properties specified in the CSS file. |
