Course Presentation

Hi... I'm a "dummy" as far as editing js or php is concerned... I've made a course presentation with a sequence of drag and drop questions. It's not responsive; on a mobile it's in miniature format, and the buttons are so tiny that it's difficult for adult fingers to move them. 

I've seen the articles about changing things so that it's more responsive, but I admit to being a bit too dense to know how to implement them. Also wondering why it's not automatically responsive anyway?

I'd appreciate any help with this!

I have one UI issues , while drag the link interaction in presentaiton. I have attached the image.

Help please

I have created an activity using the course presentation activity type. On the first slide I am using the exportable text area for students to answer a question. The next slide provides a model answer and then the final slide (automatically appears when viewing) with the following buttons

1. Show solution
2. Retry
3. Download text input

How can I disable "show solution" from appearing as it does nothing for this type of interaction?

I have enabled Override "Show Solution" to no avail

thanks
