YOOtheme template - January 2009.
This is YOOtheme's first template to come with overrides for the Joomla core. It means that they got rid of Joomla's tables. The whole content area is free of tables now, and they developed very neat CSS for their overrides, too. They did that to give you full control over the look of your website. Now you can easily style every part of your Joomla website with CSS. They also rewrote all of Joomla's core components and threw out a bunch of unnecessary code, so now your site will load faster as well.
Also they optimized their module framework. From now on every styling you can apply via the module class suffix will work on any module position, no matter what kind of background that position has.
Their typography got polished, too. There are a couple of new elements like the drop caps you can put at the beginning of paragraphs and left and right insets to align your content more easily.
