CSS Classes vs Id

Sometimes I forget which one uses the # symbol and which one uses the '.' when defining these elements in your style sheet. In fact, when should you use one over the other? What rules govern the selection of classes or id's?

Here is a nice little article from www.tizag.com that may help you out.

Sticky Footer - Footer stays at the bottom

Saw this on Richard's blog over at Akiramedia. I know I've needed this in the past - haven't tried this technique yet though. If you get it to work please leave a comment on this post.

Keeping site footer at the bottom

I recently ran into a CSS issue that I could not figure out. I wound up contacting Richard over at Akira Media about it and he sent me to this site:

http://www.themaninblue.com/writing/perspective/2005/08/29/

It describes a technique using CSS that will keep a footer at the bottom of a browser window no matter how big the browser gets or how big the content gets.

Note: you must know the height of the footer for it to work and I wound up having to use some line breaks (
) inside the div tag right before the #footer div to make it work. I tested it on IE7 and the latest Mozilla and it seemed to work ok.

Validate your css

Here is a link to a site where you can validate your website's css.

http://validator.w3.org/

You simply type in the url of the page you want to check and click 'Check'. This will validate your site's markup and return a page that will either congratulate you on your excellent coding skills or tell you all the bad things about your css.

Having valid css and html is important for good SEO because.....well, I'm not really sure why but I would think the cleaner your site and the less errors and bugs you have the better.

The cleaner your code is, the easier it is for spiders to search your site. There...I think that's probably the reason why - I guess. :)
