Hello Beatriz,
Did you find a solution to this?
We’re having the opposite issue to John: the scrollbar appears for our students but not admins – it isn’t easy to consistently replicate but means that for many students the end of the question or the check/finish buttons are cut off and you have to scroll to see them.
We did an update to Moodle 3.9 last week and since then a style class (highlighted in screenshot below) has been automatically inserted into the iframe of every H5P we have embedded (in addition to the width and height info that was there before) – we don’t know where it is coming from as it isn’t in the original H5P embed code. We can’t edit it or delete it – Moodle always just changes it straight back to what it was.
While we’re happy for the width to be set to 100% if this means the H5P is responsive, the given height apparently can’t be changed: sometimes we are left with a height of just 147px so the students are left with a tiny iframe window through which to view the quiz, which is understandably frustrating!
Please can anyone advise on how to make H5Ps consistently responsive so they appear without the scrollbar, or at the very least remove/edit the new style class in the iframe?
Thank you in advance!
