Upgrade Your HTML is the book series for HTML craftspeople and minimalists.
In Upgrade Your HTML IV, HTML and CSS optimizer Jens Oliver Meiert takes 10 more examples of HTML from actual websites in order to analyze, explain, and improve the respective markup.
Apart from discussing the appropriate use and the subtleties of HTML elements, this edition covers general topics like conformance, maintainability, and the balancing of optimization vectors. It also covers topics like attribute minimization, void elements, metadata, table buttons and button links, and even CSS art.
“Optimizing and minimizing HTML and checking if there are more appropriate elements or attributes to use is a helpful exercise, because it can improve accessibility while you learn about new features.”—Simon Pieters
