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

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 ?

Using angular 9.0.0rc with flex-layout": "^8.0.0-beta.27

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 !
