Highlight line ranges

[jimthedev]

Hello! Another idea that I'd love to see is the ability to highlight several lines. I realize this would be at odds with it being editable since you'd probably want to attach the highlight to a specific content that just happens to live on a certain line. In the case of non editable though I'd love to see the ability to highlight various line ranges.

Is this something you think might be possible and/or would be open to?

Thanks!

It's definitely something I'm open to in general. It might come in quite handy. However, there might be certain limitations when using the CSS Highlight API to highlight lines. Ideally, highlighting lines would not require markup changes.

A quick, basic POC implementation looks something like this e.g.
