Is there a way to change the Twitter Bootstrap Modal window animation from a slide down effect to a fadeIn or just display without the Slide? I read through the documentatio
The modals used by the bootstrap use CSS3 to supply the effects and they can be removed by eliminating the appropriate classes from modals container div:
As you can see this modal has a class of .fade, meaning it is set to fade in and.in, meaning it will slide in. So just remove the class related to the effect you wish to remove, which in your case is just the .in class.
Edit: Just ran some tests and it appears that that is not the case, the .in class is added by javascript, though you can modify he slideDown behavior with css like so:
.modal.fade {
-webkit-transition: none;
-moz-transition: none;
-ms-transition: none;
-o-transition: none;
transition: none;
}
