In developing the dialogs I have used an external dialogs.css file, but with dialogs nearly about to be merged in to the repo for inclusion into 8u40, more thought has to be given to CSS styling. My plan is to copy the content of dialogs.css into modena.css. Hopefully from this point someone more talented in styling can become involved and improve the style in the modena.css file, and then do the same for caspian.css.
