When I open the twitter bootstrap modal dialog, the backdrop causes a scrollbar and shift the content.
To avoid the scrollbar I use this css:
.modal
I had the same issue with the scroll bar disappearing, and the body shifting to the left when opening a bootstrap modal.
I've found out an easy fix:
.modal
{
overflow-y: auto !important;
}
.modal-open
{
overflow:auto !important;
overflow-x:hidden !important;
padding-right: 0 !important;
}
Good luck to all!
