Detailed HTML quick reference guides with color-coded browser and standards compatibility. Both the HTML Card and HTML Foldouts show all tags for XHTML 1.1 (HTML 4.01) with their attributes and values. All style sheet properties are shown with their value syntax. Special characters, like copyright, typeset quotes, em-dash, or European language characters, are shown with their names, numeric codes, and where possible, keystroke shortcuts used in most Windows applications. A functional index lists all HTML and Style Sheet features by category. The HTML Foldouts are larger print and fold smaller. Three foldouts are sold as one Tags, Styles, and Characters. The HTML Card is dense as a phone book (same font in fact), with all tags and styles in the center-page-spread. Also includes a heavily annotated example, an HTML-to-XHTML checklist, URL part diagram, and a brief SSI reference.
Used these back when I used to build and maintain my own web pages. Came in handy and now that I'm getting back into HTML wish I could remember where I put them.
