Unrelated to the article, but I love the "glow" effect on the code snippets. Any chance this exists as a plugin for VSCode, for when I want to re-live my teenager dreams of what working on computers looks like?
Yeah, and it's pretty simple. You have essentially three composition layers: original text; a gaussian-blurred zero-offset "shadow" to add glow (CSS text-shadow); and then a pattern of darker horizontal stripes on top, produced with repeating-linear-gradient with an alpha channel.
