The Web Development Glossary is probably the largest of its kind. With more than 2,000 terms and explanations it acquaints and reunites you with the major standards and concepts of the Web, with HTML, CSS, JavaScript, accessibility, security, performance, code quality, internationalization, localization, editors and tooling and more.

The glossary then goes beyond web development, touching on computer science, design, typography, usability and user experience, information as well as project management, other disciplines of interest and relevance to the modern developer. It goes beyond, inspiring the curiosity to learn more about the Web and the people creating and using it. And still it is a glossary, of a couple of thousand terms for developers, leaning on (and giving back to) Wikipedia and the MDN Web Docs.

HTML is super-popular. Everyone can write HTML. Or can they? In the spirit that everything can be tweaked and optimized, Upgrade Your HTML is a first light book in a playful series to review and improve real-life examples of HTML.

Not shyly but always constructively does Jens Oliver Meiert, someone who has written a lot of HTML and who makes his own life difficult so that he can write even more HTML, go through ten samples to ponder and upgrade the respective markup.

If you’re a web developer you know HTML. Check out and follow Upgrade Your HTML to nod (or shake your head) exploring old and new problems surrounding uses of the beloved HyperText Markup Language.

→ This is the book if you enjoy the intricacies of working with HTML.

The Little Book of Little Books consists of three booklets, originally released in 2015 and 2016. They have been lightly updated and edited (with permission and release by the former publisher, O’Reilly).

The Little Book of HTML/CSS Frameworks provides guidance for the development and use of web frameworks. It was written during a time when frameworks were used by linking to their style sheets. While times have changed, it’s the author’s conviction that the principles outlined in the book still hold, and that it provides unique views to the advantage of everyone working with frameworks.

The Little Book of HTML/CSS Coding Guidelines outlines the benefits of coding standards and discusses them on the basis of the Google HTML/CSS Style Guide. It was written during a time when there was little tooling to format code automatically. Back in 2012, the author had revised and published the Google guidelines; many years later, he maintains that the modern frontend developer and their craft still benefit from such standards.

The Little Book of Website Quality Control reviews quality assurance and control and offers a comprehensive collection of tools. It was written during a time when there were few automated testing options, with a focus on web-based manual testing. The author believes this has been one of his weakest books, ponders why he didn’t do better, but likes the idea that, over time, he can make updates that make it a little less shallow.

→ This is the book if you want to travel back in time for a complementary perspective on frameworks, coding guidelines, quality control—and the craft of web development.
