Add padding references for all button sizes to Style Guide

[soniakaukonen]

Style guide is missing an illustration of padding in buttons with icon left/right (styles).

Refer to XD, note mistake in small icon without icons should be 12 instead of 8px.

This will be (partially?) addressed with the new site template which uses a much better way of displaying the specs automatically... here's a screen grab:

Do you think that will suffice? it uses Popover CSS Inspector, a JavaScript library which I created recently. More demos at: https://coliff.github.io/popover-css-inspector/

Looks good, that would save us lots of manual work. The only issue is to get an example of:

• text only
• button left and text
• text and button right

@coliff How are we doing on this? I'm inclined to close as not planned.

I think this should be left open. We should add specs as popovers as suggested by Sonia.
