FAQ

• Can I use Youtube domain to get thumbnails?
  • I am not sure if it will work in all cases, but you can try. You need to adjust JavaScript.
  • Change line 24: settings_thumb_base_url = 'https://img.youtube.com/vi/';
  • Change line 88: this_content.style.setProperty('--yt-lazyload-img','url("' + settings_thumb_base_url + this_data_id + '/maxresdefault.jpg")');
• Can I use Youtube lazyload with other frameworks like Bootstrap?
  • Yes you can! There should be no conflict with other frameworks.
• Can I embed video players other than Youtube?
  • Check out our sister project for Vimeo Player: https://github.com/the-muda-organization/vimeo-lazyload
