Problem/Motivation
Original statement:
Need to build out the spinning circle throbber for use in autocomplete and ajax loading events based on the Proposal: A Style Guide for Seven.
Motivation is discussed in more detail in the style guide.
Proposed resolution
(To confirm: does this issue cover approving the new spinner into core? Or is this issue just about coming to some sort of agreement regarding the style guide element[s]?)
Replace the existing spinner with a preferred SVG version, falling back to a GIF for older browsers.
Testing instructions
The spinner is used on taxonomy fields (entity reference, taxonomy term), so from a clean install you can just add an Article node and check the tags field – see #9 for instructions on what CSS to change to keep it running continuously, and how to check the fallback animated GIF.
The spinner is also used is Place Blocks. From a clean Drupal install, enable the Place Blocks experimental core module. This will add a Place Block option (with a lego brick item) to the right of the toolbar. Click this and you'll get a screen where every region has a plus sign. The spinner is displayed when the plus icon is clicked.
Remaining tasks
1. Write/propose patch. (done: #9)
2. Trial patch. (done: #14)
3. Identify where the spinner is not being applied. (#17)
4. Re-roll/add to patch, in order to cover all instances where spinner is required.
5. RTBC patch.
User interface changes
Superficial, in line with the style guide.
API changes
n/a although patch as stands includes the Modernizr library in its assets.
Data model changes
None.
