Does this screen shot look the way you'd like it
(with respect to the button sizing and placement)?

Here's a larger shot

#3: why do the paddings on SIGN OUT and RESET TO DEFAULT seem different?

These don't look correct to me. There seems to be >4px on the RHS and <4px on the LHS

@michaelpg, I uploaded a new image. They should align consistently - though they still may need to be moved a bit.

@bettes, the thing that is confusing me is that the margins are 20px and the button placement is 12px + 4px and the buttons should line up with other elements. There are 4px unaccounted for that I'm trying to understand better.

Sorry, to clarify it'd be 12px + 8px :)

And that's also true for buttons and vertical separators. 8px between left edge of button-bounds and rule-line

Alan, should the buttons with a solid blue background line up on
their outer button edge, or line up on their text label (just like
the other buttons)?

I chatted with Alan. He requests that in the one case where
the blue background button is in question, that we change that
button to be blue text on a white background. (Then line it up
by the text label).

[MD settings] change button padding and placement

This CL changes the button padding to be 12px on each side and
causes the button padding to extend into the margins so that
the button text lines up with the .settings-box margins.

The button style for Sign Into Chrome has also changed from
an action style to a primary style.
