Have you visited 9to5mac? The continuity of their page scroll is a commendable feature.

However:
  • Wix.com
  • format.com
  • Yola.com
These, would be the basic recommendation.
 
I would prefer a drag and drop designer. I found the Coffeecup Responsive Site Designer, it's available for both Windows and Mac...but it's so expensive. 😡

You can also try "Pinegrow web designer" and "Bootstrap Studio" : both allow you to drag and drop responsive websites using the bootstrap framework. You'll still need to know html and how the bootstrap components all fit together though. I bought both at a sale end of 2016 for about 30 or 40 dollars each.
 
Thanks all. I ended up installing Virtualbox on the PC, so my friend can edit her sites using a Mac app, she didn't want to pay for both a Windows and a Mac version. While evaluating different apps, I liked Coffeecup Responsive Site Designer the most, my friend liked a Mac web design app called Wolf. Both are very good drag and drop tools, we are pretty proud of our new site designs. 😛
