WYSIWYG Web Builder is a (What-You-See-Is-What-You-Get) program used for creating your own web pages.
WYSIWYG ensures that the finished page will display exactly the way it was designed - by you. The program generates HTML (HyperText Markup Language) tags while you point and click on desired functions; you can create a web page without the need to learn HTML.
WYSIWYG Web Builder allows you to drag and drop objects to the page, position them anywhere you want, and when you're finished, publish it to your web server (using the build-in Publish tool). You can then fully Customizable menus, toolbars, keyboard accelerators, dockable windows, tabs, and autohide windows since web page-creator gives you full control over your web content and layout page.
