vertical align with flexbox in IE11 and IE10 - css

Question

How to make a cross browser solution where an element is vertical aligned?
http://jsfiddle.net/e2yuqtdt/3/
This works in both Firefox and Chrome, but not in IE11
<div class="page_login">
<div>vertical-align:center; text-align:center</div>
</div>
html, body {
height:100%;
}
.page_login {
display:flex;
height:100%;
width:100%;
background:#303030;
}
.page_login > div {
margin:auto;
background:#fff;
min-height:100px;
width:200px;
}
update
When the centered element is higher than the viewport height the background is only 100% and not 100% scroll height
http://jsfiddle.net/e2yuqtdt/8/
html, body {
min-height:100%;
height:100%;
}
.page_login {
display:flex;
min-height:100%;
height:100%;
width:100%;
background:#303030;
}
.page_login > div {
margin:auto;
background:#fff;
height:800px;
width:200px;
}

How to make a cross browser solution where an element is vertical
aligned?
Take a look at this fiddle: http://jsfiddle.net/5ry8vqkL/
The technique applied there is using the "display: table". Here is an article for an in-depth view of the approach http://css-tricks.com/centering-in-the-unknown/
Supported browsers can be seen here: http://caniuse.com/#search=table-cell
HTML:
<div class="container">
<div id="page-login">
<div class="panel">Some content</div>
</div>
</div>
CSS:
html, body {
min-height:100%;
height:100%;
}
.container {
display: table;
height:100%;
width:100%;
background:#303030;
}
#page-login {
display: table-cell;
vertical-align: middle
}
.panel {
height: 100px;
background-color: #fff;
}

You need to add a height to the div. As you have only specified a minimum height, IE automatically expands it to the max possible. So add a height, like this:
.page_login > div {
margin:auto;
background:#fff;
min-height:100px;
width:200px;
height:200px;
}

As this is a flex box, and therefore meant to flex, a good idea could be to make the height a percentage. So the div height would be - for example - 50% of the page height, unless the page was less than 200px high - then it would be 100px high.
Update: Unfortunatly it is not possible to make the div fill the whole page with only CSS. However it seems it is possible with Javascript, see here Make a div fill the height of the remaining screen space
Actually - have achived it using tables divs
http://jsfiddle.net/e2yuqtdt/14/
<div>
<div id="div1">
<div id="div2">vertical-align:center; text-align:center</div>
</div>
</div>
#div1 {
display:flex;
height:100%;
width:100%;
background:#303030;
}
#div2 {
margin:auto;
background:#fff;
height:800px;
width:200px;
}
I know this update is coming after the one by elad.chen - but had already done this and posted it in the comment below - just hadn't got round to updating the question.
