Form with custom Input Button not submitting

thank you nevsie )
yes, i know that

the css has been made by a friend of mine. i know it's kinda weird
and from time to time, pretty ugly

i myself know a little bit css but still trying to figure it out.

by the way, without the css classes and the div of the button, it works.

so definitely a css issue.
