Halcyon Theme Manual
Halcyon marks a golden age for grid themes. It's polished, gorgeously flat, and incredibly color-customizable. An evolution of the iconic masonry theme that adds as much as it refines, Halcyon is a confident, all-purpose face for virtually any blog.
Variable Post Sizes
Like our other grid themes, Halcyon's posts can be tagged either "medium" or "large" to expand their size beyond the default small width. Content on permalink pages will display at medium width unless tagged otherwise, though only video, photo, and photoset posts can be tagged "large."
Halcyon is the most colour-customizable theme we've ever made. The Theme Customization Options for color include: Additionally, Halcyon's Sidebar and Metadata fields can be color-inverted to white, fitting darker color customizations
Sidebar Twitter & Instagram Feeds
Setting up your Instagram feed is simple: just go here, retrieve your Access Token, and paste it into the appropriate field within the theme customization options. Twitter is even easier. Head to your blog's general settings to connect your Twitter account, and it'll auto-populate. Done.
Sidebar and Metadata Opacity Control
Near the bottom of Halcyon's customization options, you'll see a "Sidebar and Meta Background Opacity" option, with a default value of "0.5". Adjusting this, of course, will adjust the opacity/transparency of the theme's metadata containers and sidebar, with "0" being totally transparent and "1.0" totally opaque.
"Followed Blog" Roll
If you're using Halcyon on your account's main blog, the sidebar will display a random assortment of 25 blogs you follow. This can, of course, be toggled off as well.
Halcyon's sizeable social media link section (in the sidebar) includes: Bandcamp, Behance, Delicious, DeviantArt, Dribbble, Email, Etsy, Facebook, Flickr, Foursquare, GitHub, Google+, Instagram, LastFM, LinkedIN, Myspace, Pinboard, Pinterest, Rdio, Skype, SoundCloud, Spotify, Steam, StumbleUpon, Svpply, Vimeo, and YouTube.
Halcyon also features easy hookup to Google Analytics.
