New submission from Joseph Hendrey : The sidebar navigation menu jitters when scrolling on the 2.7 documentation pages (at least in Chrome). A seemingly unrelated issue is that the collapse symbol '<<' is a fixed distance from the top of the page rather than staying in the centre (height-wise) of the screen (it should always be visible). It seems it has been fixed for newer documentation, but since the fix is so simple it would be nice to fix it for the old documentation too. Setting the position property of the span element seems to fix both issues for me (see attached screenshot) ---------- assignee: docs@python components: Documentation files: screenshot.JPG messages: 308834 nosy: Joseph Hendrey, docs@python priority: normal severity: normal status: open title: nav menu jitter in old documentation type: behavior versions: Python 2.7 Added file: https://bugs.python.org/file47343/screenshot.JPG _______________________________________ Python tracker https://bugs.python.org/issue32393 _______________________________________
