The oik.css file contains a number of definitions of classes for defining fixed width or min-height blocks, typography and so on. What do I need to do in order to apply overrides to these definitions? For example, when I use the [bw_address] shortcode the address is always prefixed by 'work'. I'd rather that this text is not displayed. Can I change the CSS to display:none? I don't believe I'm supposed to edit the file directly. What options do I have?
