Joomla – Making a Custom Home Page
Giving the Front Page a different style from other pages – from Joomla Docs
I specifically used the following CSS method from the above post:
Assigning CSS style on the body element in your template
Edit the file “index.php” in your default template directory
<?php $active = JFactory::getApplication()->getMenu()->getActive(); ?> <body class="<?php echo $active->alias; ?> ">
Then, you can write CSS rules which style the component differently on the body.home page.
body.home .AsideLeft {
/* different rule for homepage */
}
