Change css?

I removed the bottom part with CSS, I remember I right click the section and open “Inspect” copied the code and then ask chatgpt to hide that element with css and that’s it, copy paste the code lol

Thanks!! Now it looks like I want to!

And here is the code if anyone wants it:
.wpcpo-total {
display: none;
}
.wpcpo-option-form {
padding-bottom: 10px;
}
.wpcpo-option-field {
width: 330px;
height: 30px;
}
