Understanding themes and their components will make it easier for you to narrow the field when choosing a theme for your website - either at the time of its initial build, or later, if you decide that your current theme is not meeting your needs.
The mechanics of choosing a theme are simple. But understanding how to use the "Feature Filter" will make finding something that works for you a whole lot easier than looking at page after page of previews.
In this first of a four-part series, we'll be looking at the various layout choces available within the Feature Filter.
