Re: Amaya: Can the default/inbuilt CSS be modified?
Yes. A graphical aid such as Amaya usually has a working subset of
available options but I think Amaya will recognise any valid css.
You can change the code by hand and also move it from in-line style
to page style or to astylesheet with a bit of effort and learning.
If you need to, give us (me) an example of what you are trying to
achieve that Amaya is not doing for you.
