Template Details

Yellowblue is a Jekyll blog theme released by author Christos Alatzas, with the repository under the Apache-2.0 license. The theme is positioned as a static blog appearance that can be downloaded, unzipped, and used directly; it requires no installation process and does not depend on additional plugins, so it can be deployed on GitHub Pages.

Functionally, the theme provides a custom grid system, categories and tags (without plugins), pagination, an archive page organized by publication date, a custom 404 page, an automatically generated sitemap.xml, and a distraction-free reading layout in which the sidebar moves to the bottom when reading posts and pages. Comments are integrated through Disqus and can be enabled or disabled globally or per post; the contact form is implemented through Formspree. Code highlighting uses Prism, and it includes 451 SVG icons from Icomoon.

In terms of appearance, the theme ships with 4 additional color presets that can be switched by changing a single word in the code; colors can also be customized with Sass variables. The README mentions mobile-first techniques for responsiveness and includes lightweight animations. The repository provides an online demo and a separate documentation site.

Usage limitations: Disqus comments and the Formspree form are external services and require configuring the corresponding account or endpoint; their quotas and fees are outside the scope of the theme code. Sample images come from Gratisography, and third-party assets such as icons and fonts must be checked against their own licenses; they cannot be judged solely by the code's Apache-2.0 license.

License & source material

Usage conditions & limitations

Free to use · keep license notice

This entry covers the free version in the public repository under the Apache-2.0 license; the free scope is the code of that version and does not mean that external services or third-party assets are free.

Must comply with when using

Free use, modification, commercial use, and distribution are permitted; when distributing, the Apache-2.0 license must be included.
Modified files must be prominently marked as changed, and relevant copyright, patent, trademark, and attribution notices must be retained.
If the original project includes a NOTICE file, applicable attribution notices in it must be retained when distributing derivative works.
The license includes an applicable contributor patent grant; initiating patent litigation as described in the license terminates that patent grant, and no trademark use rights are granted.
The code is provided as is; warranties and limitations of liability are governed by the original license and applicable law.

Additional costs & items to verify

The comment feature depends on the third-party service Disqus; you must register a Disqus account and configure the site shortname yourself, and service quotas and fees are determined by Disqus and are outside the scope of the theme code.
The contact form depends on the third-party service Formspree; you must register an account and configure the form endpoint yourself, and free quotas and pricing policies are determined by Formspree.
Sample images come from Gratisography, whose license differs from the theme code's Apache-2.0 license; they must be checked separately before use or replacement.
The 451 SVG icons come from Icomoon; the license for the icon assets must be checked separately and cannot be judged solely by the code's Apache-2.0 license.
The Open Sans font comes from Google Fonts and must be used under the font's own license, which is unrelated to the theme code license.
The README mentions the Formspree form service; actual submission requires configuring a service endpoint, and its usage quotas and fees must be checked separately.
Demo images, fonts, icons, and other third-party assets must be checked against their own licenses and cannot be judged solely by the code's Apache-2.0 license.
External services such as domains, hosting, databases, payments, or AI may incur additional charges.
