Change Log

FancyBox library was updated to v3.5.1 - it contains a lot of improvements and bug fixes
------------
Changelog:
*Improvements:
**New option preventCaptionOverlap (enabled by default for desktop only) prevents caption from overlapping the content;
**HTML5 video now uses thumbnail image as poster;
**Redesigned caption - centered, without top border and does not hide when idling (and preventCaptionOverlap is enabled);
**It is now easier to set content height in % (especially for iframes), there is no need to adjust bottom margin and max-height (caused by this - https://bugzilla.mozilla.org/show_bug.cgi?id=748518), because bottom margin is applied automatically using JS)

*Fixes:
**Fixed thumbnail visibility detection (now works better with sliders);
**Fixed share modal not closing when clicking outside content area;
**Fixed iframe support for iOS
