Sidekick

Sidekick is a Superhero child theme without the bells and whistles. It’s a clean, widget-free, single-column theme that looks great with any content, but excels at displaying panoramic featured images.

Stripping out the sidebar widget area, featured content slider, and fixed header gives Sidekick a spartan appearance, but like all great sidekicks, this theme brings something special to the team. Sidekick uniquely displays panoramic featured post images in a responsive, full-bleed manner.

Featured images must be at least 1500 wide and have an aspect ratio of 3x1 (width x height). You can set featured images on the Post Editor page under Featured Image.

This theme is not available in the WordPress themes repository. So it can be used only on WordPress.com blogs and not on self-hosted WordPress.
