Sorry, could you help clarify how are the styles included?
Hi! I have added this gist long time ago, cannot even remember how it works :). Also not sure if i got you right.
-
If question was "how to add styles?" then you can check next options:
Option 1: SASS + webpack -> dimsemenov/PhotoSwipe#1374 (comment)
Option 2: https://photoswipe.com/documentation/getting-started.html -> 'Step 1: include JS and CSS files' -
If styles added and you wounder how then pls prepare demo in codesandbox.io. Maybe I can help you then.
Thanx a lot for offering your help!
I ended up figuring it out for myself. I am building a lit-element wrapper for photo-swipe, and this is how I set up the styles:
static get styles() {
return [
css(require('photoswipe/dist/photoswipe.css').toString()),
css(require('photoswipe/dist/default-skin/default-skin.css').toString()),
`,
];
}
