angular - Angular 2 ngStyle with browser prefixes

Question

This is not working:

<div [style.-moz-column-count]="columns"></div>
<div [ngStyle]="{'-moz-column-count': columns}"></div>
<div style="-moz-column-count: {{columns}}"></div>

Is there any workaround to avoid Sanitizer? I found a Pipe to bypass the value, but not the property name.

import {DomSanitizationService} from '@angular/platform-browser';
@Pipe({name: 'safe'})
export class SafePipe {
    constructor(sanitizer:DomSanitizationService){
        this.sanitizer = sanitizer;
    }

    transform(style) {
        return this.sanitizer.bypassSecurityTrustStyle(style);
    }
}

Any ideas to use this property?

Answer 1

You need to write this like this:

this.style = {
  "MozColumnCount": 3,
  "column-count": 3,
}

<div [ngStyle]="style">

Answer 2

I don't think it's possible with angular2 ngStyle.

You could go with ngClass option and scss like this:

@for $i from 1 through 6 {
    .columns-#{$i} {
        -webkit-column-count: #{$i};
        -moz-column-count: #{$i};
        column-count: #{$i};
    }
}
