> Dear list.

> https://splines.readthedocs.io/bezier.html
> What I don't like, however, is that those animations are always

>     <div class="animation" align="center">

> I've tried to work against this forced center alignment by including
> this snippet in the notebook:
>     <style>div.animation { width: fit-content; }</style>
> But I'm wondering: is there a better way?
> There must be a better way!
> I would like the animations left-aligned because the normal plots are

> I'm also wondering: shouldn't the alignment be an optional setting?
> Furthermore, the "align" attribute of "div" elements is "obsolete" and
> "deprecated" according to
> https://developer.mozilla.org/en-US/docs/Web/HTML/Element/div
> Shouldn't the alignment probably be removed completely?
> If I'm using to_html5_video(), the animation isn't centered either, so
> this would be actually more consistent.

That seems like a convincing argument. Would you open an issue with this in
