Summary
In this 79‑second video I walk through a quick test of the highlight functionality that I originally built but later abandoned due to HTML restructuring. I start by showing that I can select multiple pieces of text; as the selection reaches the top of the viewport it anchors so the selection isn’t lost. I then demonstrate that the existing highlights appear and explain that I now want to add a new highlight colour. By clicking the colour buttons I toggle the highlights: clicking the blue button turns the selection blue, the orange button makes it orange, and a "no colour" option clears the colour. When I press the yellow button, all current highlights switch to yellow. I also show how clicking each colour a second time removes that colour from the highlighted text – orange disappears when I click orange again, yellow disappears when I click yellow again, and finally clicking blue clears the last highlight. I mention a document that David wrote earlier about the nuances of highlights and note that what I’m doing follows that guidance. After the colour‑switching demo I refresh the page, copy the highlighted content, and paste it elsewhere to prove the copy‑and‑paste works. Finally I toggle a dark‑mode view, point out how the highlights look in that mode, and conclude the short demo.
