Widen posts

It appears the Papatya theme is using Blueprint CSS framework. The width of the main content area and sidebar are controlled by class=16 and class=8 last respectively. There is a second stylesheet called screen.css (at least in their demo site) that determines the width of those elements.

Understand that if you change things in the stylesheets it can really mess up how things work as Blueprint is a grid framework.

However, if you do want to change the width you can go to your template pages and change the class. Remember always make a back-up first. For example (again going off the demo site), this is for the the two divs below <div class="span-24 id=contentwrap">, if you change <div class="span-16"> to <div class="span-18"> and <div class="span-8 last"> to <div class="span-6 last"> this will increase your main posts width and decrease the sidebar. Play around a bit, just make sure to always have a back-up of your files.
