Introduction: HTML-Kit is a free text editor with a lot of features. Writing simple XHTML, CSS and even JavaScript is extremely easy. With XHTML, your elements and attributes can be inserted by double-clicking the pop-up menu that comes up. CSS is colour coded so you can see what you typed. For serious PHP and ASP developers, HTML-Kit also assists with that. Regular functions are bolded so you know if you made a mistake somewhere. JSP, RDF, Perl and many, many more file (including the rare ColdFusion) formats are there for you to work with easily.
