I am an absolute beginner. I've got a JavaScript project in which I must 'format specific elements differently depending on the type of browser used'
and I have no idea what to do with that. Should I check out how the code displays in diffrent browsers and then figure out how to optimize it or is there some kind of guide that shows which elements display diffrently?
I would be really grateful for any answer.
You can use JavaScript to detect the navigator.userAgent to get the name of a browser.
https://caniuse.com/ is a webpage you can check to determine if a certain feature is supported by a browser.
Sara Cope wrote an article about the "appearance property" that you might find helpful for disabling default styling of HTML element.
