As a part of our work on new Key Management System (KMS) for rclone, it was more than appropriate to look for prior art. There are well-tested cryptosystems providing file encryption for file systems built on top of block devices. However it has turned out that these systems offer little to no inspiration for an object storage systems encryption.

During the years, there were many cryptography-related articles published on our blog. Many of those contain mathematical formulae using LaTeX notation. The time has come to render those again and one JavaScript package turned out to be just the right ingredient we needed.

Last week on January 24th, version 5 of Qi was released. This release contains support for flows in higher-order argument positions and in sequences of qi/list procedures a faster runtime code is produced by the compiler.

In the previous part Dark Mode Toggle without Javascript, we demonstrated how to set up CSS variables and style the wrapper div container. In this second part, we will focus on styling the toggle itself.

The following code snippets of HTML and CSS demonstrates a simple setup to enable dark mode using only HTML and CSS, without any JavaScript. This solution takes user preferences into account and allows the user to manually toggle between light and dark mode. Practical example can be seen in the header of this page.
