In this tutorial we will work with both ID divs and Class divs and differentiate the difference between the two. Class divs can be called upon thought your site. To best explain, at this website you will notice horizontal ads along the top of most pages, these ads are placed inside a class div as I use these divs multiple times with no need to change their attributes. However, say I changed the size, border, colour or any other attribute, and then the change would be applied to all. With an ID div this can only be called upon on one occasion, so if you have a particular part of your page you would like to change using a div and you only wished this change to apply to one page then you would use an ID div.
