Importing Web Page into Pages

I'm a self-publisher who's trying to figure out the best way to create epubs and paperbacks.

My editors all use Mickeysoft Word, so I had to install that on my laptop. I discovered a really slick way of copying a manuscript into Word.

First, I copy the text from an epub I created with a software program called Sigil and paste it into an HTML file. Next, I put all the images in a folder so they display correctly. I can then view the file in a browser, copy the entire thing and paste it into Word. The text and images are both copied into Word, and about 80-90% of the styles are preserved.

I decided it's time to learn how to use Pages, but I discovered that the above trick doesn't work. When I copy everything on a web page and paste it into pages, all that appears is a couple lines of text.

So my question is, what's the best way to import a file - including images - into Pages?

Thanks.
