title: Is there a way to change HTML text styles line by line in js?
body: <p>This is a bit of an unusual question, but is it possible in javascript to change text styles for every other line? Let me be a bit more specific. Assume I have a page with several paragraphs. What I want to do is alternate text styles (font color or background color) for each line, as they appear on my screen.</p>
  <p><a href="https://i.stack.imgur.com/tOU2p.png" rel="nofollow noreferrer">Here's the idea</a>. I'd like to make a browser extension that automatically colors every other line in a paragraph to make it easier for readers to follow along with what they are reading on a page. Thoughts? If it's possible, how should I go about writing this?</p>
