Repro steps

Step1: install node_modules for the above provided project.

Step2: run ng serve

Step3: Open the browser devtools and focus the element with class "sample-div", which has display:grid as applied style.

Desired functionality

The .sample-div should also contain the prefixed style which is display: -ms-grid like in Angular 6.

This is the indented behaviour in Version 7 see: https://github.com/angular/angular-cli/pull/11453

To enable autoprefixing for grid you need add /* autoprefixer grid: on */.

@alan-agius4 Where should I add /* autoprefixer grid: on */ ? This is unfamiliar territory for me.

You can try to add this comment in your scss / css files. If you put this comment on the top, it will enable grid for all the file. If you set it in a declaration block, grid will only be available inside this block.
