Demo

Link

Playground

You can play with gallery using Plunker or CodePen

Prerequisites

• Font Awesome (required for icons)

npm install font-awesome --save

For angular-cli based projects insert styles into .angular-cli.json

"styles": [
    ...
    "../node_modules/font-awesome/css/font-awesome.css"
]

• Hammerjs (required for swipe)

npm install hammerjs --save

import 'hammerjs';

SystemJS

If you are not using SystemJS you can skip this section.

map: {
  'ngx-gallery': 'node_modules/ngx-gallery/bundles/ngx-gallery.umd.js',
}

Angular Material

If you are not using Angular Material you can skip this section.

Angular Material is using transform: translate3d(0,0,0); in components styles. Unfortunately transform changes positioning context and preview won't work properly. To avoid this situation you have to override material styles, for example:

@import "~@angular/material/prebuilt-themes/indigo-pink.css"; // your theme

.mat-sidenav-container, .mat-sidenav-content, .mat-tab-body-content {
    transform: none !important;
}
