Hi Catherine, thanks for resolving these minor adjustment we discussed last time.
Maybe this one can adjust a little more (not sure if it is my local issue):

May also reduce table margin to the top of background to be equal. Thanks.:

Hi Ian, the input height fix is done in the shared stylesheet, will publish a new version and import again later. The table margin is like that in the design, but I saw next version the margin will be reduced when we add tap, maybe we can change when work on the next version.

I see, I am confused what style in where but other than that sounds good. Thanks.

We still left some minor style changes (button on focus effect, input height) in the common theme repo, but those are really tiny ones, we could wait to release the new theme version later.
