Flex layout display problem with Safari IOS using fx-layout="column" - css

Question

We are currently using Angular as a front-end with fx-layout api for responsiveness.
When we are using the fxLayout="column" all elements are collapsed and doesn't seem to have any height.
What are the best practice when using fx-layout/flex to handle these scenarios ?

Answer 1

The problem with safari occur on this element (second container in the mat-card-content):
<div fxLayout="column" fxFlex fxLayoutAlign.xs="center center">
The flex on safari resulted with a weird exponential number in the CSS something like this : flex: 1 1 1.12e-16
Changing fxFlex for fxFlex="grow" generated on safari this css flex : 1 1 100% which fix the height !
