Jekyll is pretty rad and figured releasing a cleaned up version of [my setup](http://mademistakes.com) as a theme to hack up and use would be cool. So here be that theme --- I call it **[Minimal Mistakes](http://mmistakes.github.io/minimal-mistakes)**, a responsive Jekyll theme with editorial tendencies.
Variables you want to update are: site name, description, url, owner info, and your Google Anayltics tracking id and webmaster tool verifications. Most of these variables are used in the .html files found in *_includes* if you need to add or remove anything.
For the most part you can leave these as is since the author/owner details are pulled from `_config.yml`. That said you'll probably want to customize the page links in `navigation.html` and copyright stuff in `footer.html` to your liking.
There are two main content layouts: *post.html* (for posts) and *page.html* (for pages). Both have large **feature images** that span the full-width of the screen, and both are meant for text heavy blog posts (or articles).
A good rule of thumb is to keep feature images nice and wide so you don't push the body text too far down. An image cropped around around 1024 x 512 pixels will keep file size down with an acceptable resolution for most devices. On my personal site I use [Picturefill](https://github.com/scottjehl/picturefill) to serve the same image responsively in four different flavors (small, medium, large, and extra large). In the interest of keeping things simple with this theme I left that script out, but you can certainly [add it back in](https://github.com/mmistakes/made-mistakes#articles-and-pages) or give [Adaptive Images](http://adaptive-images.com/) a try.
The two layouts make the assumption that the feature images live in the *images* folder. To add a feature image to a post or page just include the filename in the front matter like so.
``` yaml
image:
feature: feature-image-filename.jpg
thumb: thumbnail-image.jpg #keep it square 200x200 px is good
```
#### Thumbnails for OG and Twitter Cards
Post and page thumbnails work the same way. These are used by [Open Graph](https://developers.facebook.com/docs/opengraph/) and [Twitter Cards](https://dev.twitter.com/docs/cards) meta tags found in *head.html*. If you don't assign a thumbnail the default graphic *(default-thumb.png)* is used. I'd suggest changing this to something more meaningful --- your logo or avatar are good options.
#### Table of Contents
Any article or page that you want a *table of contents* to render insert the following HTML in your post before the actual content. [Kramdown will take care of the rest](http://kramdown.rubyforge.org/converter/html.html#toc) and convert all headlines into a contents list.
**PS:** The TOC is hidden on small devices because I haven't gotten around to optimizing it. For now it only shows on tablets and desktop viewports...
``` html
<sectionid="table-of-contents"class="toc">
<header>
<h3class="delta">Contents</h3>
</header>
<divid="drawer"markdown="1">
* Auto generated table of contents
{:toc}
</div>
</section><!-- /#table-of-contents -->
```
#### Videos
Video embeds are responsive and scale with the width of the main content block with the help of [FitVids](http://fitvidsjs.com/).
Not sure if this only effects Kramdown or if it's an issue with Markdown in general. But adding YouTube video embeds causes errors when building your Jekyll site. To fix add a space between the `<iframe>` tags and remove `allowfullscreen`. Example below:
