Styling Individual Joomla Pages
One of the most frequently posted questions in the Joomla! forums is:
"I need to style my HOME page differently from the rest of the pages. How can I do this?"
While there are many, many MANY ways to do so, one of the best I have seen was recently posted by user "beanluc".
I am reproducing this as an image, so you won't be able to copy/paste it, but it's only 3 lines, four counting the body tag.

The three lines are inserted just before the closing head tag, and then the body tag is altered.
For those new to Joomla!, the end result is that one can set CSS styling based on:
- Whether or not the current page is the home page.
- The Menu ID of the current Page.
This may not sound like any kind of break through, and it isn't a cancer cure, but it gives a developer/designer enormous freedom to control the appearance of any (and every) Joomla! page.
and that's what it's all about.
