I found that ie browser have problem to vertically align inner containers, when only the min-height style is set or when height style is missing at all. What I did was to add height style with some value and that fix the issue for me.

for example :

.outer
    {
       display: -ms-flexbox;
       display: -webkit-flex;
       display: flex;

       /* Center vertically */
       align-items: center;

       /*Center horizontaly */
       justify-content: center;

       /*Center horizontaly ie */
       -ms-flex-pack: center;

        min-height: 220px; 
        height:100px;
    }

So now we have height style, but the min-height will overwrite it. That way ie is happy and we still can use min-height.

Hope this is helpful for someone.


Try wrapping whatever div you have flexboxed with flex-direction: column in a container that is also flexboxed.

I just tested this in IE11 and it works. An odd fix, but until Microsoft makes their internal bug fix external...it'll have to do!

HTML:

<div class="FlexContainerWrapper">
    <div class="FlexContainer">
        <div class="FlexItem">
            <p>I should be centered.</p>
        </div>
    </div>
</div>

CSS:

html, body {
  height: 100%;
}

.FlexContainerWrapper {
  display: flex;
  flex-direction: column;
  height: 100%;
}

.FlexContainer {
  align-items: center;
  background: hsla(0,0%,0%,.1);
  display: flex;
  flex-direction: column;
  justify-content: center;
  min-height: 100%;
  width: 600px;
}

.FlexItem {
  background: hsla(0,0%,0%,.1);
  box-sizing: border-box;
  max-width: 100%;
}

Here is my working solution (SCSS):

.item{
  display: flex;
  justify-content: space-between;
  align-items: center;
  min-height: 120px;
  &:after{
    content:'';
    min-height:inherit;
    font-size:0;
  }
}

The original answer from https://github.com/philipwalton/flexbugs/issues/231#issuecomment-362790042

.flex-container{
min-height:100px;
display:flex;
align-items:center;
}

.flex-container:after{
content:'';
min-height:inherit;
font-size:0;
}

Just in case someone gets here with the same issue I had, which is not specifically addressed in previous comments.

I had margin: auto on the inner element which caused it to stick to the bottom of it's parent (or the outer element). What fixed it for me was changing the margin to margin: 0 auto;.
