Hopefully this is not too broad, I am currently developing a website for my university project and part of the criteria is to implement some considerations to accessibility and also responsive design. Which got me thinking about the user experience for people with visual impairment, now with the current front-end frameworks when the user zooms using the browser it will begin to use the media queries and break down the site which includes reducing the font size to accommodate the restricted width, which really rejects the users desire to enlarge the content.
Now looking on various resources, including w3c guidelines this issue is not really addressed and I am wanting to know, is this because it is not a problem? and would it help to put all media queries in a separate CSS file that the user can disable from being used?
