questions to ask (HTML/CSS)

apparently value doesn’t strictly need to be provided for checkboxes. if it’s not provided, then what value would it default to on the backend? (in the sense that with the one example, for a radio button with name="indoor-outdoor", the default value if either of the radio buttons was clicked would be indoor-outdoor=on.
step 68 says “One more thing. You should allow people to use their native language. Tell the browser to encode multiple languages by adding a meta element as a child of the head element. Set its charset attribute to UTF-8.” but in what way does this allow people to use their native language?
jess mentioned she would bring up some things about how the web works or how browsers work but she didnt end up mentioning that as far as i could tell… does she have links or recs to learn more about that?

would anyone really use this complicated method to make a menu layout? is there any good reason not to use a table for this?
- another better way is probably to use the method shown in the nutrition label lesson of warapping a span around the price and giving it float right

why use background-color instead of background, if the latter is more flexible (can take either a color OR an image)? i guess it’s more explicit and that makes for more readable code?

what’s the definition of viewport anyway?
Why do they have us use a percent for one and vh for the other? Is it because 100% height could take up more than one screen length, whereas 100vh takes up only exactly one screen length?
What would happen if the parent element of something with height: 100vh was more than one screen long?
any difference between using an input element vs button element for the submit button? is there a best practice about it?
are there any guidelines for when to use a select dropdown vs when to use a series of radio buttons?
