A new word is being used to describe some WordPress themes, “responsive WordPress themes”. This descriptor is used when a theme can fit any screen size without needing multiple versions of the design. For example, a theme that adjusts when the screen size changes without reloading or redirecting to a “mobile” version.
There is a simple test for whether or not a theme is responsive. Visit the theme, make sure the browser window is not maximized, and drag the corner of the window in and out, changing the size of the viewable window. If the theme gracefully adjusts without losing perspective, key features or dimensions, the theme is responsive. Think of it like the theme is responding to the window size.
Of course, there is some pretty tricky coding that goes into creating a truly responsive theme. If you already know how to create a WordPress theme (not using Artisteer) and you have a basic knowledge of CSS, you can check out this tutorial on creating a responsive WordPress theme.
