Bootstrap: How to center vertically an element
Question
I'm doing a website that will be mostly displayed on a mobile. I'm using bootstrap 4.
Currently I'm trying to display an element that has to be "vertically" centered in the available space.
By this I mean: I've a title, which use a fixed size, and I've one message + 2 button in a div that I need to display in the vertical middle of the available space(without overflow).
I found this: vertical-align with Bootstrap 3 --> the bootstrap 4 snippet doesn't work One other answer which was about flexible box was promising, but it seems that if I have only one component that should use all the remaining space it doesn't work.
Also, one thing; the element that I need to have vertically aligned is displayed through a jquery call:
$('#btToShow').click(function(){ $('#card-container').fadeOut(200, function(){$('#wait-for-result-container').fadeIn();}); }); $('#change-choice').click(function(){ $('#wait-for-result-container').fadeOut(200, function(){$('#card-container').fadeIn();}); });

Any idea how I can align the content of #wait-for-result-container vertically in the middle?

You can vertically center content with flexbox
#wait-for-result-container {
display: flex;
align-items: center;
justify-content: center;
height: 100vh;
}
To fadeIn with display: flex
$("#wait-for-result-container")
.css("display", "flex")
.hide()
.fadeIn();

You could just position it absolutely:
#wait-for-result-container {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
$('#btToShow').click(function(){ $('#card-container').fadeOut(200, function(){$('#wait-for-result-container').fadeIn();}); }); $('#change-choice').click(function(){ $('#wait-for-result-container').fadeOut(200, function(){$('#card-container').fadeIn();}); });
#wait-for-result-container { position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%); }

This method works really well for Bootstrap 3.x:
#wait-for-result-container {
position:absolute;
left:0;
right:0;
top:50%;
-webkit-transform:translateY(-50%) !important;
-ms-transform:translateY(-50%) !important;
transform:translateY(-50%) !important;
}
top:50% sets the position of the div 1/2 way down the container, then transform:translateY(-50%) shifts it back up half the distance, making a nicely vertically centered object relative to the parent container.
