>I'm trying to do my first application with HTML5+CSS+JavaScript, but I don't find a tool for programming like VFP, "form" designers, reports, etc.

Lianja provides the tools that allow you to create business apps without having to learn not only the tools you mention but a lot you didn't.

Creating what's needed, including issues in resizing, different screen dimensions, etc. is incredibly complex. Whole frameworks have been written, and continue to be invented, for doing that. In fact, the complaint of those using the frameworks is that there's always a new one to learn.

In Lianja V6.4, in development, we will also have the essentials, aselobj() and amembers(), in the same manner as we do in VFP.

Lianja is not a tool for writing web sites. It is a tool for writing business applications that run on the web, on desktop, tablets, and phones. WebAssembly (which gives access to devices on the host device) is a matter of a checkbox and filling in a few essential fields.
