Editing the content code directly

Hi. I'm trying to create a drag and drop text type of question but using the front end iterface seems difficult for making the drop zones and text boxes sizes/positions exactly as I want them by dragging. Can anyone tell me if there's any way I can edit the code directly and then paste/upload it back there. For example, in Wordpress there's an option to switch between visual editing and code editing.

I'm using H5P in Moodle 3.9 (not the H5P Moodle plugin).
