I am an Android software engineer starting to work on a side project that requires a web app.<p>On android, I used to use the gui editor to get the rough GUI (layout, size, proportions) I wanted and then finalized it in xml/java.<p>I was wondering how I could go about doing so on the web?<p>I started using React + BlueprintJS to get all the components I needed, but everything looks very ugly without having CSS hacks (or custom styles) all over the place.
