I'm mainly a back end dev, but with a new in-house project I need to be able to ship a simple HTML page with the outputs of another process (like a report). Id prefer to avoid the bigger css and js frameworks if possible when making a biscuits layout, for transportability, simplicity, and conflict minimisation.
What is your go to for a very simple HTML page drag and drop style builder? Despite the simplicity desired I'd still like something at least a little nice looking.
