Having the exact same issue. It seems to be because of the addition of /#w-tabs-0-data-w-pane. Once a tab is clicked anywhere on the page, the page moves up to the top (and in some cases down to the bottom). Very frustrating, it wasn’t doing this yesterday.
+1 — tabs have been working for weeks while working on a project published to domain.webflow.io, but published today to custom domain and experiencing the exact same /#w-tabs-0-data-w-pane issue and scrolling to top of page
the blue border around your tabs is native browser functionality and needed for accessibility options like screen readers, and keyboard only navigation. you can overwrite this style but it’s definitely not suggested without implementing a workaround in order to stay ADA compliant. you’d be looking for the ‘outline’ css property on said element — https://codepen.io/anon/pen/axBjdm
Jason is correct, we fixed this pretty quickly after the issues surfaced in March. If it doesn’t fix on republish, please contact support@webflow.com. Thanks, and sorry for the inconvenience!
