#Code Guide

This is a repository of pre-made layouts and code snippets that are free for you to use (non-commercially). Check individual posts for details. A few notes:

  • Page themes are platform agnostic layouts and can be used anywhere that supports (modern) HTML/CSS. They use CSS variables to manage user settings so you can swap out colors, images, fonts, etc. These variables are located in the :root element. If you’d like to know more about CSS variables, you can read this guide.
  • Page themes are meant to look identical to previews out-of-the-box, so they come shipped with web URL images rather than local links. I encourage you to link your content locally.
  • For instructions on installing a Tumblr theme, you can read their official documentation.
  • Attribution is nice, but not required.

“I recently decided it might improve user experience to get a loading screen instead of watching the grid unceremoniously disentangle itself. A few experiments later, and here we are.”
