Expected behavior I want to use a fluid modal on the right side for my contact form. As I have a second sticky nav under the main top navbar I need the fluid modal to have a top offset of 100px. Then I would like to have the modal-body to be set to "overflow-y: auto" to give space to larger content. Actual behavior Tried setting the modal to position: relative; top: 100px. This does it but it hides 100px of the modal under the viewport. So in the case of my contact form the "submit" button stays under the viewport ... Does anyone have an idea on how to achieve this? Thanks in advance!
