vertical align with flexbox in IE11 and IE10

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

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;
}

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.
