You need to set a higher z= on the textbox that contains the iframe. You can't click the buttons because there are other things above it.
I still don't quite understand what you mean with initial ratio. How exactly do you want the iframe to scale?
Thank you C7N.
About intial ratio i mean the content is responsive, but even with a large player i can't get the desktop display i only get the mobile one.
I've set a higher z= on the textbox that contains the iframe, but content on lower z are not clickable anymore. So i removed the Choice menu.
I'm trying to do something WSE is not for i know, but i need a solution to display that kind of page. I'm working on an experimentation in story telling and webpage.
Ah, now I understand what you mean. Well, it seems to me you might have to write an extension or custom function that opens the iframe outside of WSE and positions it over the stage. I think the reason it ignores the responsive design is because the stage gets scaled using CSS and that includes the iframe as well. So even if the stage is large (like when you hit F11 for fullscreen) the iframe still has the same "width" as when the stage is smaller.
Thank you for the answer !
I'll study your idea of an extension or a custom function.
