Reset CSS for student submission render

[BTWS2]

The difference between the render with clean CSS and the render on Dodona isn't beneficial for the students. If the render is not reliable, a separate editor is required and it is less user-friendly.

If teachers want to grade HTML&CSS exercises it's easier if the render is reliable.

Rowspan isn't visible in this example.

The Dodona doesn't support iframes in the student submission render.

@bmesuere suggests these options:

• solve with CSS

#tag { all: initial; }

#tag * { all: unset; }  /* or */

#tag * { all: revert; }

Edit: Tested without the desired result.

• Solve with iframe

"alles wat je in die ruby file opgeeft zal geoutput worden naar html je moet 2 dingen outputten:
een lege iframe (bv met een id, hoogte en breedte opgegeven)
en dan een script tag waar je bv via document.getElementById de iframe selecteert en dan de srcdoc property instelt" - Bart

"Iframe is miserie omdat je bv de hoogte niet automatisch goed krijgt en dan moet je JavaScript truuken uithalen om dat te fixen" - Bart

If the render is not reliable, a separate editor is required and it is less user-friendly.

Dodona is not an IDE, so a separate editor is required either way. Students shouldn't be coding in Dodona.
