Another question: How can I prevent the preview from scrolling up to the start of the page??
Every time I insert a new tag in the editor, this happens.
That’s just how Codepen works I think. It reloads the page when you add/change something, so the pages starts from the top. It gets annoying for long pages like the technical doc. page. I put in the nav bar right away so that I could use it instead of scrolling!
Actually there’s a way, I just remembered. Go to Settings>Behavior then disable Auto-Updating Preview. That way you will have to click Run to get your page to update.
