Quickblog gives you the ability to customise the style of your blog with some coding, if you're familiar with CSS, or if you want to work with someone to do it for you.
You can add a css file from a URL or you can enter the CSS manually in a text box. This option will change the styling for your entire blog (global), however, Quickblog will soon support local styling for individual blog posts.
In order to get started, simply go to your Blog Settings -> Layout Settings and in the General Settings, scroll down to the bottom:
