Vertically Center Bootstrap Modals to Fit in Browser Window

Oct 23, 2024 by Christine Cardoso in Bootstrap

340

Vertically center bootstrap modals without setting a height. Modal max-height will not exceed the window height with scrollable .modal-body and adapts on resize. You will need these JS and CSS snippets:

function adjustModalMaxHeightAndPosition(){
  $('.modal').each(function(){
    if($(this).hasClass('in') === false){
      $(this).show();
    }
    var contentHeight = $(window).height() - 60;
    var headerHeight = $(this).find('.modal-header').outerHeight() || 2;
    var footerHeight = $(this).find('.modal-footer').outerHeight() || 2;
    $(this).find('.modal-dialog').addClass('modal-dialog-center').css({
      'margin-top': function () {
        var mH = $(this).outerHeight(); 
        var wH = $(window).height();
        return (mH < wH ) ? -( mH * 0.6): -( wH * 0.5) + 12;
      },
      'margin-left': function () {
        return -($(this).outerWidth() / 2);
      }
    });
    if($(this).hasClass('in') === false){
      $(this).hide();
    }
  });
}
if ($(window).height() >= 320){
  $(window).resize(adjustModalMaxHeightAndPosition).trigger("resize");
}

function adjustModalMaxHeightAndPosition(){

$('.modal').each(function(){

if($(this).hasClass('in') === false){

$(this).show();

}

var contentHeight = $(window).height() - 60;

var headerHeight = $(this).find('.modal-header').outerHeight() || 2;

var footerHeight = $(this).find('.modal-footer').outerHeight() || 2;

$(this).find('.modal-dialog').addClass('modal-dialog-center').css({

'margin-top': function () {

var mH = $(this).outerHeight();

var wH = $(window).height();

return (mH < wH ) ? -( mH * 0.6): -( wH * 0.5) + 12;

'margin-left': function () {

return -($(this).outerWidth() / 2);

}

});

if($(this).hasClass('in') === false){

$(this).hide();

}

});

}

if ($(window).height() >= 320){

$(window).resize(adjustModalMaxHeightAndPosition).trigger("resize");

}

.modal-dialog-center {
    margin: 0;
    margin-bottom: 12px;
    position: absolute;
    top: 50%;
    left: 50%;
}
.modal-footer {
    margin-top: 0;
}
@media (max-width: 767px) {
  .modal-dialog-center {
    width: 100%;
  }
}

.modal-dialog-center {

margin: 0;

margin-bottom: 12px;

position: absolute;

top: 50%;

left: 50%;

}

.modal-footer {

margin-top: 0;

}

@media (max-width: 767px) {

.modal-dialog-center {

width: 100%;

}
