Thanks! It has some cons, like worse scanability. But I think its really cool that you can have something open next to your paragraph, especially when you need to consult the popup quite often. Like, a table with a bunch of data would also be quite nice with this approach I feel.
i've been wanting to implement a design like this for blogs for 5 or 10 years. Great work on the inline detail on mobile. genuinely better than whatever i would have made.
did you consider pushing the word(s) directly following the activation button to below the detail pane, rather than doing it based on line break?
If you have any feedback I'd love to hear it!
