It appears to me that one the author's points is that the problem is not with HTML or CSS, but basically with Web IDL. We are forced to use JavaScript for HTML and CSS manipulation, but it could be avoided with better interfaces. E.g., if we could painlessly create <input type="location"> and describe its API and behavior from our JS… which apparently isn't possible with current implementation. See also another author's post at http://infrequently.org/2011/10/real-constructors-webidl-last-call/ http://infrequently.org/2011/10/real-constructors-webidl-las.... > Without looking anything up, design a three-column layout where all columns have equal height even when their contents are unequal. I can see your point, but this particularly is not that hard: http://jsfiddle.net/fbJ6J/ http://jsfiddle.net/fbJ6J/. I know, I know, but it does comply with your requirements. =)
