Storytime is a simple, well-designed blogging theme perfect for writers (and not only).
You can fully customize your website colors, add a full-screen image for the homepage, choose the background for other pages.
There is a layout option with a sidebar and without it. You can customize which elements should be displayed for single posts and for archives.
In addition to the sidebar and 4 widgetized columns in the footer, there are also several widget areas in the site’s header where you can put banners or other ads.
