Subject: Re: Font selector using radio button

In your copy of the Agile book, look at the section entitled "working 
with non-model fields" (section 22.7 or 23.7 depending on which edition 
you have). Replace text_field_tag with radio_button_tag or check_box_tag 
as appropriate. Then your controller can read params[:color] or 
whatever, and style the response appropriately.

You'll find more info in the Rails API documentation under 
ActionView::Helpers::FormTagHelper - go to http://api.rubyonrails.org/

However I'm afraid your question has very little to do with Ruby (the 
programming language).

For help with Rails (the web application framework), you would be best 
advised to ask your question on a Rails mailing list or forum. There are 
some Rails users here, but this is not the primary focus of this mailing 
list.

For help with styling web pages, you could ask a CSS mailing list.

If you want the style changes to be reflected immediately when someone 
presses a button, you'll want to use Javascript and/or a Javascript 
helper library (I prefer jQuery over Rails' default Prototype). Again, 
there are separate mailing lists for those.

HTH,

Brian.
