additional tip:

--settings-toggle-height-and-width: {
  height: 12px;
  width: 28px;
};

--paper-toggle-button-checked-button: var(--settings-toggle-height-and-width);
--paper-toggle-button-unchecked-button: var(--settings-toggle-height-and-width);

This works iff the the --settings vars are declared before they are
used. Using the vars within the {} allows the --settings vars to be
sorted. I'm assuming that replacements are something akin to a 
breadth-first traversal (based on the behavior I'm seeing).

I can make the values unsorted and use this method if that's preferred.

why are you declaring these AFTER using them?  does this work with native custom
css props?

[dschuyler, 2016/08/29 23:48:13]

I had defined them above and then got a notice when trying
to submit the CL that they should be alphabetical. I tested
and it seemed to work. I didn't specifically test native
vs. non-native.
