Starting work on interface for 'turbo scrolling' on phones or desktops.

I have a hobby site that needs a good interface that allows quick scrolling. it will kinda work like an outline where user scrolls between items with ability to drill down probably 2 levels. but I'd like to be able to have both a condensed and card interface together. maybe if scrolling of the left of the screen its stays in condensed view so scrolling is quick but if scrolling on the right the item currently in the middle goes into card view with extended text describing the item in more detail. I might start working on something in jsfiddle to show better what I want, but gemini AI says codepen is better to prototype for smartphones. I would like to optimize the interface for smartphones either android or ios, but be reasonably functional on desktops. has anyone seen anything like this or have opinions about codepen? submitted by /u/LastCivStanding [link] [留言]
