HTML and CSS

• Follow mdo’s Code Guide, with one exception: Use four spaces for indentation (instead of two).
• Use .lowercase-and-dashes for class names and #camelCase for IDs.
• Add a comment marking the end of large blocks. Use <!-- end class-name -->

<div class="container-fluid">
    Lots of markup...
</div><!-- end container-fluid -->

• Avoid inline CSS. Prefer CSS classes for maintainability and reuseability.
