Drag & Drop Website Builder Tool that gives you the code?

We are building a simple web application (school assignment). We have basic programming skills and are wanting to code the back end ourselves.

We are wanting to know if there is a drag and drop tool available for our front end i.e., a tool that allows us to click and drag the html elements to create the interface.

We need the drag and drop tool to provide us with the code (so we can copy the code into our IDE and commit our work through git.)

Does anyone know of any tool we could use to achieve this?

We ideally need a tool that is free / open source if possible?

Thanks in advance :)
