Answer 1

It works as expected.I am not sure what are you facing ?

Answer 2

The code works perfectly. Not sure what you are experiencing.

Answer 3

Your code is running prefect. The color, border and font are changing.

Answer 4

Your code is working fine.

Is there anything specific you want to know?
Or trying to advertise your creation? If yes, use appropriate thread for that.

Answer 5

you don't actually need the <form></form> containers since you are not submitting to a server.
maybe you put the button inside a form container before refactoring yor code. That would trigger a post action and refresh the page resulting in a blank page in Sololearn.

try this:

<form>
<button>click me and the page goes blank</button>
</form>

<button>click me and nothing happens</button>
