Admit it: Your seven-year-old nephew could out-HTML tag you any day and you think that a Cascading Style Sheet is something with a thread count. That’s where Mediabistro comes in. Our mothership has just confirmed its next online course in HTML and CSS, and it’s never too early to start planning ahead. Over four fun-filled weeks, web design design guru Laura Galbraith will guide you through a variety of web page production techniques, from column-based layouts and search engine optimization to semantic markup and advanced CSS styles. The online learning fun begins September 15, and by Halloween, you’ll have brought a pre-designed webpage to life through the magic of HTML. Preview the course syllabus and register here.
