Sidebar animation transition no longer works

[choldgraf]

Describe the bug

After the latest PyData Sphinx Theme upgrade, I think our sidebar animation stopped working. It now just "snaps" into its end state. I'm not sure what exactly changed :-/

To Reproduce

Go to the sphinx book theme docs and click the "hide sidebar" button.

cc @DrDrij - any chance you've got an idea what might be wrong?

Hi @choldgraf.

These lines that were removed are for adding the animation to the bootstrap functions.

We could re-add them? Or I could have another pass early next week to simplify and avoid future issues.

&.collapse { visibility: hidden; margin-left: -$leftbar-width; opacity: 0; display: block; &.show { visibility: visible; margin-left: 0; opacity: 1; } }

For sure - I was only removing them because much of the sidebar css had now been incorporated into the pydata theme so i was removing it here to avoid duplication. I just didn't realize i was deleting this functionality in the process haha. Let's add it back in 👍

#333 tries to add them back in per your suggestions, let me know if that looks OK
