Line Focus Reading Ruler

Losing your place in a dense block of text, then rereading the same line twice, is a common small frustration while reading online.

A soft highlighted bar follows your cursor or scroll position, keeping one line of text visually distinct from the rest.

Adjust the highlight height and color to fit the text size and your own visual comfort.

Toggle it on only when reading a long article, and off the rest of the time with one click.

Works over any page's regular text without changing the page itself in any permanent way.

A small tool that genuinely helps some readers keep their place, especially in long, dense articles.
