Foolishly Responsive

Honoring April Fools’ Day I have created a foolishly responsive accordion control. Typically a responsive effort shoehorns a large pattern into a narrow viewport, often based on iDevice screen sizes. Less typically a responsive layout will also consider viewport height, and far less typically a responsive layout might even consider…

Maybe Don’t Use Flow Charts on GitHub

In February the GitHub blog announced users would be able to Include diagrams in your Markdown files with Mermaid.

This block of code came across my Twitter timeline today framed as a CSS tip to prevent text selection on a web page: html { user-select: none; } For funsies, I dropped that CSS on this very page you are reading (assuming you are reading it in the browser). It…
