I need a to be directed to a in depth video tutorial that explains css external style sheets. Video or videos need to explain rules, classes, id's, tags, etc. Must show how to create, edit, and attach a style sheet in Dreamweaver (any version/however not to old). Video must show step by step how editing 1 .css file can change the look of your entire website. Tutorial must be done in Dreamweaver. Tutorial video can on be hosted on youtube or any other video site. Serious recommendations only.
