Sparkle is a new web page editor for the Mac, now available in public beta form. It's still pretty raw, but the first version should give you an idea of what the developers are going for - web page design using a page layout metaphor. It's a bit like Pages for the Web.

Sparkle lets you assemble a web page by simply dragging and dropping objects into place on a grid layout. No HTML knowledge is required to build a working page or complete site. Sparkle can optimize the web pages you build with it for mobile devices.

Sparkle's developers have published the app to get feedback from users. They want to hear what new features you need, what problems youhave with the interface, and any other roadblocks to getting Sparkle to produce the web content you want. If you're willing to jump in early and give it a spin and drop them a line, I'm sure they'd appreciate it.
