How can I change the height of text fields of a contact form without affecting the submit button?

I didn’t like the high height of text fields in a contact form of my travel blog, so I was able to reduce the width with the code in the first photo. However, it also changed the submit button (see second photo) that comes as part of the form. The submit button didn't have his own block ID. How can I leave the submit button as it was (bigger height)? Is it possible?

Change

input

to

input:not([type="button"])
