Using Clearing Divs
When coding a website in CSS and XHTML many people like to have two columns. To get this you use the "float" attribute in your CSS. The can align one column to the left and the other to the right. What many people find troubling is having two floated columns in a centred holder. When coding a website you usually call this holder the "wrapper". Also when designing and coding a website you generally want to make the site centrally aligned.
