There are several types of website design software available,
but by far the one that is most used is known as what you see is
what you get (WYSIWYG) software. Unlike an HTML editor that shows
the markup code for a site, WYSIWYG software allows a website to be
built graphically, sometimes using premade components or templates.
Once a site has been built, the software can usually use the
rendering engines from popular browsers to test the appearance of
the site before it is published. When choosing graphical website
software, it is important to make sure the editor is a WYSIWYG
editor and not an HTML or CSS text editor.
