How to adjust canvas size for canvas slider plugin to make the display constant across all screen sizes?

[prashantig25]

Hi All,
In my task, participants are presented with a canvas drawn stimulus and are asked to respond with the slider. Thus, I use the canvas-slider-response plugin. One of the parameters that I can adjust is the canvas size. If it is at the default of [500,500], the prompt and the continue button no longer fit in my screen. That is, I have to scroll down to see them and respond. This also means that for different screen sizes, some participants may have to scroll down and other may not have to. If I change the canvas size and reduce it so that the prompt and the continue button are displayed without scrolling, that adjustment makes sense only for my screen. Again, it can't be controlled across various screen sizes.

Is there a way to keep the canvas size constant so that these variations don't occur?

I have attached the screenshots of the same. Any help in this respect is appreciated.

Thank you.
