Customizing magritte/pier

I am looking for some tips/info on how to customize the look of magritte/pier components. My first excursion found this quite difficult. Since it appears that textInput's always have class='text'. I solved this by wrapping them in a div class='agent-code' in a custom component and using the following to effect the styling. .contents form .agent-code input.text { width : auto; } What would be the correct way to change the pier login buttons to 'Login' 'Cancel' rather than 'Save' 'Cancel'. Do I subclass PULogin, and change its asComponent to take the std component and search for its FormDecoration for the button label in order to change it? many thanks in advance Keith
