IE 11 partial support!
see can i use"-ms-flex "

IE11 requires a unit to be added to the third argument, the flex-basis property see MSFT documentation
In IE10 and IE11, containers with display: flex and flex-direction: column will not properly calculate their flexed childrens' sizes if the container has min-height but no explicit height property. See bug.
IE11 does not vertically align items correctly when min-height is used see bug

IE11 requires that a cell be added to the third parameter. See the MSFT document
in IE10 and IE11, if the container has a minimum height but does not have an explicit height attribute, containers with display:flex and flex-direction:column will not be able to correctly calculate the size of their curved child nodes.
IE 11 does not align items vertically correctly when using the minimum height
