DHTML INFORMATION
Dynamic HTML or DHTML is a collection of technologies used together to create interactive and animated web sites by using a combination of a static markup language (such as HTML), a client-side scripting language (such as JavaScript), a presentation definition language (Cascading Style Sheets, CSS), and the Document Object Model.
There are numerous DHTML Editors available, from online editors to open source (free) software programs. Additionally, you may want to consider purchasing a professional DHTML Editor.
