[GNC] Change layout and font sizes in Transaction Report - how?

[Chris Green]

The Transaction Report probably provides the information that my
auditor wants by listing each account's transactions in order and
giving the total amount below each account.

However the formatting and font sizes seem a little odd and I'd like
to change them if I can.

I have two fairly simple requirements:-

    Increase the space below "Total for <account name>" before the
    name of the next account appears.

    Increase the font size for the account name that appears at the
    top of each account's transactions.  As it is at present it's just
    in the default small size used for all the 'body' text and so the
    name doesn't stand out to indicate the start of the next account.


I can 'do' CSS but there don't seem to be any obvious selectors for
the items I want to change.  Is there any detailed description of what
selectors are available in the CSS stylesheet?
