I’m going to enclose two screen captures. I’m trying to create master slides for questions, that respond reasonably in all the layouts, with little tweaking required to individual slides.
I have a layout that works reasonably well, I think, with nested grids - question text at the top, question in 2nd row/left col, and media in 2nd row right col, then a row below that with the submit button centered. (I had to make this 3 columns because I couldn’t figure out how to keep the button from going full width when I had that row at a single column.)
Is there a better/easier way to lay this out? I found with the standard master slides for questions, things overlaid themselves and generally looked bad at narrower widths.
My main question though is how to get the media that I insert in the 2nd row to full width and auto-size to height. I see no settings to do that. Without that, it distorts badly at different widths.
You can use the Lock Aspect Ratio function: select the Media > Properties pane > Size & Properties tab > Lock Aspect Ratio: select Width or Height to maintain the aspect ratio of a flex child according to its width or height respectively.
You can totally do it for all objects at once by selecting all objects > Properties pane > Size & Properties tab > Text Box > Text Scale.
