{% include toc icon="columns" title="Included Layouts" %}
The bread and butter of any theme. Below you'll find the layouts included with Minimal Mistakes, what they look like and the type of content they've been built for.
## Default
The base layout all other layouts inherit from. There's not much to this layout apart from pulling in several `_includes`:
*`<head>` elements
* masthead navigation links
* {% raw %}`{{ content }}`{% endraw %}
* page footer
* scripts
**Note:** You won't ever assign this layout directly to a post or page. Instead all other layouts will build off of it by setting `layout: default` in their YAML Front Matter.

## Compress
A Jekyll layout that compresses HTML in pure Liquid.
To enable add `layout: single` or better yet apply as a [Front Matter default]({{ base_path }}/docs/configuration/#front-matter-defaults) in `_config.yml`.
### Header
To add some visual punch to a post or page, a large full-width header image can be included.
**Note:** Be sure to resize your header images. `~1280px` is a good medium if you aren't [responsively serving up images](http://alistapart.com/article/responsive-images-in-practice). Through the magic of CSS they will scale up or down to fill the container. If you go with something too small it will look like garbage when upscaled, and something too large will hurt performance.
The space to the left of a page's main content is blank by default, but has the option to show an author profile (name, short biography, social media links), custom content, or both.
#### Author Profile
Add `author_profile: true` to a post or page's YAML Front Matter.

**ProTip:** Custom sidebar content added to a post or page's YAML Front Matter will appear above the author profile if enabled with `author_profile: true`.
