If you read my earlier post about Adobe killing of Homesite you may have thought so what will I (and others) use now. I am very happy to say and recommend a great product called TopStyle. Initially developed by Nick Bradbury of whom was the original developer of Homesite, TopStyle is now being further developed by Stefan van As.
As a long time user of TopStyle Lite that was included with some Homesite installs I can happily say that the latest version, TopStyle 4, is a remarkable product. Originally designed to be for css documents, Topstyle 4 has now been expanded to cover most web code formats from html, xhtml, php, asp and so many more.
