Survey Form - Build a Survey Form

Tell us what’s happening:
Hello, i’m actually working on my first solo project for certification on html and i wanted to have a tips on something i maybe made wrong ? i’m working actualy on css but there is something i don’t get.

i would like to have my input take 100% of his parents ( form → main )
what i’ve done, work on the FreeCodeCamp page but if i read my code with chrome or edge the input textbox go like 3/4 pixel after the main group.

i’ve try to put some color on my code to see every part, i also put a test div with 100% width to see but this do what i expect, only the input is weird.

edit: my css have 2 different part input {} because i was doing some test sorry, in start it was in same group
