Is your feature request related to a problem? Please describe.
I use theme-ui on daily basis on personal and work projects. The documentation is quite large and I just want to remember something that I used before so I navigate the whole docs to get it.

Adding search in docs page will make it easy to remember things fast instead of navigating the documentation.

**Describe the solution

Describe the bug

GitHub provides a few options when configuring a new repo like: license, .gitignore file, a README.md, and the Rennovate plugin. If you want to install any of these by default, which I usually do, then you get an error about the remote having newer content.

To Reproduce
Steps to reproduce the behavior:

1. Create a repo with a readme during the script
2. See the er

Sites such as https://notes.apiscp.com/ or https://openshift.ktz.cloud/ where you need to scroll the tag list doesn't allow you to select the latest ones as the theme selector overlays them.
