Thumbnail style update

This thumbnail style update seeks to showcase our images with clean, simplified styling and captions, to highlight their beauty without distraction. It will also bring consistency with the new image galleries, image styles on mobile and most Main Pages.



Summary of the change

 * Image border styling is removed
 * Image box background color (previously #F9F9F9) is removed
 * Image margin and padding is increased between the thumbnail and adjacent text
 * Image caption text-size is altered (to 0.85em from 0.875em) for better readability at the decreased size and to distinguish it from body text
 * Image caption text-color is changed to better distinguish it from body text (from grey #252525 to #555).
 * Magnify icon is removed (now that MediaViewer enlarges images by default)

Timeline

 * Postponed. See Talk:Thumbnail style update

FAQ
  Was there an on-wiki discussion about this change?   Yes, this was discussed at length during the Typography Refresh discussion,[Link missing.] but a decision was made to implement the change separately from the Typography Refresh BetaFeature graduating, in order to have additional testing.   Does this affect infoboxes?   No. They don’t use the “thumb” parameter. No images that are not thumb styles are impacted by this change.   Does this affect video or audio files?   Video and Audio files which rely on the same styling (CSS) as the image thumbnail style will be updated as well. Images and video which use special templates or in-line styles may not be affected.   Does this affect all skins or only the default (Vector) site skin?   This change only affects the default site skin (Vector). </dd>  What happens to articles with in-line styles on images? </dt>  In-line styles will not be overridden.
