Hi Lynn
Download the free 30 day trial and see for yourself.
http://www.xara.com/us/web-designer/ The trial copy is fully functional and you can create and publish a website. But you do not have access to the Content Catalog.
I have used Xara products since 1995 when I first saw what was then CorelXARA being demonstrated.
I prefer Designer Pro X365 because it can do web and print work and has all the best features. But it is also considerably more expensive.
Web Designer is a WYSIWYG program so you put things on the page where you want them and Web Designer does the rest. You can use/modify the pre-designed websites and templates or create your own sites and mobile sites from scratch.
