Shifts around when resizing and scrolling.

Can you share a screenshot?

Looks like a French-style quote.

Probably just a 1-2 line CSS fix. I'll take a look when I get on a real machine.

Hi @mariehuynh, This looks like the sidebar open/close is not rendering properly on Android. I don't see the same behavior on Safari or Chrome when sized to mobile width.

[mariehuynh]

I reproduced the problem on Chromium on Debian, and Chrome on a Mac, by reducing the size of the window and then scrolling horizontally.

I don't see any CSS in this repo that affects this, and traced the problem back to the default CSS in Sphinx. We can override it via something like

div#sidebarbutton span { position: sticky; }

in tools/static/custom.css

Thanks for the research @mariehuynh. I'm glad you were able to reproduce. Your suggestion seems like it will work. We may also see if the fix should be contributed back to the Sphinx project.

I can make the change and run some tests. Can you point me at your protocol for testing before submission? What browsers are officially supported?

[ezio-melotti]

I think it's best to fix this upstream on Sphinx. Once the patch has been tested and accepted upstream we can either apply it here directly, or wait for the next Sphinx release. We also don't have a specific list of supported browsers (other than "the main ones"), but Sphinx might.

Adding that here for future reference:

I've not seen this since we moved to Furo (https://github.com/python/devguide/pull/679), let's close this unless someone can still reproduce.
