panel is misaligned

Can you post a link of where you are seeing this so I can replicate easily?
It surely is on dev instance not really sure about prod
What page on dev instance are you looking at ?
From what I can see, the issue here is this rule:
.Tools .btn-notice { margin: 35px; }
Your patch only fixes this because #read-options is a more specific selector than .Tools .btn-notice (ids trump classes)
I think instead of overriding in this fashion it would be better to remove/update the .Tools .btn-notice rule.
Here is a screenshot with margin: auto. It competes with .Tools .btn-notice and takes precedence as I wrote in [pull]

Leaving out margin-left does not help:

Instead adding margin: auto:

Is that clear?

This is wrong as .Tools .btn-notice does not apply here.
Is the margin of 35px on .Tools .btn-notice needed anywhere? If so, where?
I can only see class="btn-notice" in macros/databarWork.html and it is referenced in:
css/components/editions.lesscss/components/Tools.lessMacro databarWork.html is used in templates:
openlibrary/templates/type/edition/view.htmlopenlibrary/templates/type/work/view.htmlopenlibrary/templates/type/edition-history/view.htmlbut nowhere with that order namely .Tools > .btn-notice so I'd say that rule is not used.
Thanks for the detective work!

I can't replicate this any more... did this get fixed?
I can't reproduce anymore. Voting to close
