CSS cleanup

[bill]

Ticket to do various CSS cleanup of dijit.css and the themes, including:

• remove unnecessarily long selectors
• remove vestigal rules
• rearrange rules so that rules for each widget are together
• move cursor rules from themes to dijit.css

[bill]

(In [21472]) Fix invalid rule, refs #10816. (Margin can't be none, only 0.)

[bill]

(In [21473]) Shorten some (unnecessarily) long selectors, refs #10816.

[bill]

(In [21475]) Dialog tundra CSS cleanup including:

• shortening selectors
• removing commented out CSS
• removed the webkit shadow for Menu because it wasn't being done correctly and actually it wasn't showing up; shadow should be specified on .dijitPopup (affecting all drop downs and popups, not just menu), with an exception for tooltip since it isn't rectangular.

Refs #10816.

[bill]

(In [21476]) Move definition for toolbar separator icon from Editor.css to Toolbar.css, so that toolbar users don't need to include Editor.css.

It's sort of in the middle though since the actual icon is in the editor sprite.

Refs #10816.

(In [21485]) Cleanup Tree CSS, Refs #10816.

[bill]

(In [21486]) Various tundra CSS cleanup, refs #10816.

[bill]

(In [21487]) Various tundra form CSS cleanup, including:

• moved all the spinner rules into the spinner file
• since all input widgets have dijitTextBox class, we can simplify selectors
• define border width for ComboBox? and Spinner buttons in dijit.css, so all theme needs to do is to specify color in normal mode and focus mode
• a combo/spinner arrow button being active doesn't affect the border color; i think that rule was just there out of fear the dijitTextBoxFocused class wouldn't be set while the button was being pressed... but it is.
• etc.

Refs #10816.

[bill]

(In [21488]) Minor tundra layout CSS cleanup, refs #10816.

[bill]

(In [21500]) Minor tundra CSS cleanup b/c dijitTextBox class is applied to all textbox based widgets including ComboBox and !Spinner, refs #10816.

[bill]

(In [21541]) Comment about <h1> margin is no longer valid, so remove it and also remove the TitlePane double border on tundra, and some other CSS simplification. Refs #10816 !strict.

[bill]

(In [21612]) Add comments and move Spinner RTL rule into dijit_rtl.css (it was the only one not there), refs #10816.

[bill]

(In [21613]) Simplify spinner/a11y CSS a bit, and make it display better (in a11y mode), so that borders don't get cut off and arrows are a bit bigger. Refs #10816.

[bill]

(In [21614]) Remove some FF workaround code that's apparently no longer needed, although hard to confirm since there is no record of why it was needed to begin with. Refs #2803, #10816.

[bill]

(In [21615]) Remove vestigal rule, currently there's no node with tabStripMenuButton class. Refs #10816.

[bill]

(In [21630]) Fix tundra RTL Select and simplify rules by using border-collapse rather than explicitly controlling which sides gets borders. Refs #10816 !strict.

[bill]

(In [21632]) Fix vertical slider labels on FF so the tick mark are next to the groove and the numbers are on the outside. I think I'm removing workaround code that was just needed for FF2. Refs #10816.

[bill]

(In [21660]) Consolidating all the rules for each widget. Refs #10816.

[bill]

(In [21662]) dijitIEFixedToolbar is defined in dijit.css, no need to put it in each theme, refs #10816.

[bill]

(In [22057]) General CSS cleanup from Doug's work on #11034, refs #10816.
