Atrium is a single-channel theme that keeps content cleanly organized with sharp lines and modular sections. Bright and spacious, Atrium’s architectural layout is the perfect framework for any form of content. It’s ideally designed for brands and bloggers.

Responsive Design


Atrium is fully responsive and scales to fit any screen size and browser. Its single-column layout and right-hand sidebar make for a robust, readable, and welcoming blog. On mobile devices, Atrium‘s sidebar moves to the bottom of your page so visitors will still have a spacious area to view your content, and the portfolio projects grid scales to best suit your screen size.


Take advantage of Atrium‘s flexible theme options to best match your style or brand. To start, add a full-width Custom Header Image or Custom Header Video. Change your Background Color to match and perfect the tone.


Use a Standard or Compact Header, toggle your Header Text on or off completely, or upload a Site Logo, depending on your needs.

Add a Sticky Post to the top of your homepage, or create a Static Homepage if your project isn’t solely a blog.

Highlight all your social media accounts – right from the Header – with gorgeous icons for over 25 built-in services.


Atrium currently includes icons for Bandcamp, Behance,, deviantART, Digg, Dribbble, email, Etsy, Facebook, Flickr, Foursquare, GitHub, Google+, Instagram,, LinkedIn, MySpace, Pinboard, Pinterest, Rdio, Skype, Soundcloud, Spotify, StumbleUpon, Svpply, Twitter, Vimeo, and YouTube.

Full-Featured Sidebar


Each widget is modular and visually separated from the other parts of your page, just like your posts. They don’t interfere with one another, and they’re easy to read. You can also disable the sidebar all together to give your posts all the glory.

Full-Width Image, Video, and Gallery Posts


When it comes to permalinks, Atrium gives featured images, videos, and galleries a prominent position above your content — perfect for calling attention to your best work, and excellent for telling better stories.

Longform Posts


With a special style for long-form content, Atrium prioritizes your essays, case studies, journals, or big announcements.




Atrium‘s functionality doubles thanks to the new Portfolio post type. You can host any personal or professional portfolios right alongside your blog or website, or use Atrium solely as a portfolio, if that’s all you need.
