Inquiry Popup Form Display Issue

Hi,

1. I want to display the inquiry modal popup in the middle of the screen. Right now it loads right at the very top of the screen. https://prnt.sc/vfxgo7

When I edit css: cdBoxWrapper top: 30px the overlay is pulling down from the top exposing the underneath of the site.

How can I fix this so this does not happen and modal opens in the middle of the page ? Ofcourse it must also be aligned correctly in mobile view so if you can provide that css fix please that would be great!

#cboxOverlay, #cboxWrapper, #colorbox {
    position: absolute;
    top: 35px; 
    left: 0;
    z-index: 9999;
    overflow: hidden;
}

Thanks
