For a great many years I used Microsoft FrontPage. But that software has long been discontinued. When it was time to completely redesign my web site, I tried a bunch of solutions and settled on Serif WebPlus X6. (There is now a version 7.) HTML 5 proved a bit of a challenge but solved with Easy HTML5 Video. Note that there is an official users’ web site for Serif WebPlus, and another, more friendly one you can find with GoogleSearch. Of course, the fully professional software is Adobe Dreamweaver, with a very steep learning curve. If you can code comfortably, Dreamweaver would probably be the best choice. For those of us who turn into frozen salt statues at even the thought of coding, WebPlus or one of many others like it will work better for you.
