It has been many years since I made any webpages. Frontpage don't seem to be around anymore, what are people using these days?
It does sort of depend on what technologies you are using on your site..
After Frontpage, since that is what you asked about, Microsoft released Expression Web / Expression Studio for a while... but ultimately that has been discontinued as well. Some of the features have been pushed into Visual Studio itself, and it's not horrible for HTML/CSS/JavaScript work, though it's admittedly far from perfect. I think it is the best (only?) IDE for web-based ASP.NET or MVC work... which is really popular in a lot of businesses.
Eclipse is usually considered the IDE to use for backend web development using Java (servlets/WARs/anything to do with WebSphere)... also really popular in a lot of businesses.
Dreamweaver is a popular IDE for web development, and it might be better for things like pure HTML+CSS+JS, but I have not used it in a long time. It's probably a lot easier because it offers a more intuitive graphical mode side-by-side with code.
