HTML-kit has a number of features that helps to create a WYSIWYG HTML editor that will satisfy the needs of a novice and experienced WYSIWYG web designer. One can easily create tables, cells and images with little or no code knowledge using html tidy. HTML-kit comes with a validation tool that helps to validate HTML code before saving it. HTML-kit also contains a drag and drop feature that allows one to drop unwanted items such as image thumbnails and buttons on the page. HTML-kit includes a "live reload" that allows one to refresh a web page in the background without restarting the server. The HTML-kit's automatic link monitoring ensures that one does not have to refresh the page when linking to another site.
HTML-kit has a color picker feature that helps one to select a desired color scheme or color combination. It has a built-in preview pane where one can view the output. A number of external programs support HTML-kit; one such example is FireFox which uses the built-in web-browser capabilities to run external programs in a separate window.
