Good sharing. Didn’t really think of that.
I have worked with a developer with a vision issue before, who uses a big magnifying glass most of the time look at the code. Was not informed of tab is helping him vs space. But definitely overall font size is crucial. He usually uses up to 40px or bigger font size. With that, both spaces and characters all enlarge, to help his viewing.
I can’t really comprehend how just adjusting the tab size but not the font will help vision issue developers. But I’m not on that shoe, so hard for me to judge. Thanks for sharing.
