Hexo Theme Dearmsdan

Hexo Theme Dearmsdan is a free, open-source Hexo blog theme built on the SeablueUI framework that transforms a standard Hexo site into a blue-toned personal blog with search, comments, and KaTeX math support. The theme's name "宝钻蓝色" translates to "Diamond Blue" and is designed to give an ethereal, airy feeling to the site.

What is Hexo Theme Dearmsdan?

Hexo Theme Dearmsdan is a Hexo theme that uses the EJS template engine and SeablueUI as its styling foundation. It takes a standard Hexo blog installation (Hexo 4.0.0 or higher, Node.js 10 or higher) and applies a blue color scheme, along with a set of built-in features that usually require separate plugins. Developed by ZHD99, the theme is available on GitHub under the MIT license. The input is a Hexo project, and the output is a fully styled, static HTML blog with additional pre-built pages.

Who is it for?

Hexo Theme Dearmsdan is for Hexo users who want a feature-complete blog theme without assembling many plugins. It suits personal bloggers who want a blue-toned aesthetic and an ethereal feel, and who need search, comments, and archiving out of the box. It's also a fit for developers who like the EJS template structure and SeablueUI, and who want example pages to adapt. Because the documentation is in Chinese, it primarily targets Chinese-speaking bloggers.

What can you do with it?

• Personal bloggers: Deploy a blog with built-in search, comments, and multi-level menus by cloning the theme and setting the theme name in _config.yml.
• Academic writers: Use the KaTeX formula support to display mathematical equations in posts, with the included example page as a starting point.
• Portfolio sites: Embed responsive iframes and use the custom pages (404, tag cloud, archives) to build a more complete site beyond simple posts.

How does it work?

To install, copy the theme folder into the themes directory, set theme: dearmsdan in the main _config.yml, and run hexo s to preview. The theme also provides markdown files for archive, category, tag, and 404 pages that you can copy into your site's source folder to enable those pages permanently.
