you have a heading with a margin-top set on top of your page like that, it will push down your which could at least lead to problems with your layout later on. You should probably set your to overflow-hidden. If e.g. matchMedia yet, but s etting up media-queries in your CSS alongside using ScrollTrigger.saveStyles() makes it work properly for me. I am not the most confident with ScrollTrigger's. See the Pen ExWxBrM?editors=1010 by ShehzadAsif ( on CodePen How this thing can be avoided so that they remain in their original position on resize on all devices.

addEventListener ( 'refreshInit', () => ( progress = ST.

create () // The relevant part to keeping the progress ScrollTrigger. code for tracing scrolltrigger progress in check const ST = ScrollTrigger. I used the following code for tracing ST progress from a post but does not seems to help instead it takes the window to top each time on window resize. On first load everything works fine but as you resize the window, animation based elements disappeared (elements go back to 'ypercent 100, opaity 0) on non-desktop devices while they should be at 'ypercent 0, opacity 1'. For example, my animations are for only desktop size devices (e.g ' from ypercent 100, opacity: 0), using ST matchmedia function for this purpose. Resizing the browser window or reopening the tab shows the scrollbar again.I am observing that scrolltrigger based animation does not revert to their original values on window resize. The scrollbar only disappears, but actual scrolling up/down still works. Open an Account entity in a new primary tab If a scrollbar doesn't appear yet, resize the browser window till it does.ĥ.

The VF page from above should render in the sidebar for the Contact page. If the component is added to the right/left side bar on an object (For example: Contact)Ĥ. This occurs when there is a VF component added to the sidebar.ġ. This issue happens only in Chrome (and does not occur in Safari nor Firefox) Vertical scrollbar on primary tab or subtab disappears if a user opens up two tabs and switches view Scrollbar for visualforce page components in sidebars disappears
