* Remove .ui-corner-all, .ui-state-highlight, .ui-state-error classes
from notice boxes.
* Use .notice, .notice-info, .notice-error classes instead.
* Replace <p> elements in notices with <div>'s so that we don't have to
work around the `margin-bottom: 1em` from <p> elements.
* Replace <h1> elements in notices with <h2>.
* Standardize info notices to use the same shade of light yellow in the
light theme.
* Switch from flat greys to cool blue greys.
* Define colors with HSLuv (https://www.hsluv.org) so that each band of
colors is perceptually uniform (has the same brightness and contrast).
* Fix commentary box not having a gap between it and the search navbar
when the search navbar is beneath the post (the default setting).
* Reduce border radius of commentary box.
Fixes the search button wrapping to the next line in Firefox. Also fixes
the search box to be full width with no gap between the search box and
the search button.
* Adjust platinum user color.
* Change alert notices to grey with blue border.
* Add padding to text <input> elements so that the text isn't right next
to the edge.
* Style <button> and <input> elements explicitly instead of relying on browser defaults.
* Style jquery ui buttons the same way as regular buttons.
* Add color variables so we can restyle form inputs in dark mode.
* Standardize the upload widget background colors (light green for success,
light red for error).
* Move the progress bar to the bottom of the upload widget.
* Change the progress bar color to blue.
* Hide the "drag and drop a file here" message after a file has
already been uploaded.
Standardize background colors to light green or light red in several places:
* Modqueue positive/negative score backgrounds.
* Modqueue quality/sample warning backgrounds.
* User feedback positive/negative backgrounds.
* Ban expired/unexpired backgrounds.
* Flag resolved/unresolved backgrounds (removed; resolved flags no
longer have a grey background because of inconsistencies in what
resolved means).
Fineprint text was variously styled with `.info`, `.tn`, `.hint`, or
`.cost-footnote` css classes. Standardize on `.fineprint` instead. Use
`.hint` only for form hints and `.tn` only for <tn> tags in translation
notes.
Incidentally changes the font size of form hints to 0.8em (was 0.7em)
and the color of fineprint to #888 (was #AAA or #666).
The "Danbooru" link in the header had a 5px top margin, which created a
small gap above the page that caused mode menu backgrounds to show
through in an ugly way.
Don't remove the bottom margin from all <p> elements in tables. Instead
remove it only from the last element in dtext blocks. This way we don't
have to also kludge <blockquote> padding to work with zero-margin paragraphs.
Better fix for #1655.
Position <span class="hint"> elements to the right of normal <input>
elements and underneath <textarea> elements. Fixes form hints being
badly positioned on some pages.
Instead of having custom code check whether the artist name is already
in use, just enable autocomplete on the artist name field. This is an
easier and more robust way to indicate tag name conflicts.
