Coding Form Cut Off

I used code from the Qgiv platform to insert a form into my website. On the back end it appears to be full view. When I go to the page in live view, the form is cut off. Help!

add to Home > Design > Custom CSS

@media screen and (min-width:641px) {
.qgiv-embed-container iframe {
    min-height: 350px !important;
}
}

I'm having the same problem.

Update. The coding on Custom CSS works for web but not mobile.

The above code for desktop only, with mobile you can add this code

@media screen and (max-width:640px) {
.qgiv-embed-container iframe {
    min-height: 900px !important;
}
}

Adjust number 900
