The Web Development Glossary is the largest of its kind. With more than 3,000 terms and explanations (“3K”), it is the book to try and extend your web development and web platform knowledge.

The glossary covers key terms and concepts of the Web, beginning with HTML, CSS, JavaScript, accessibility, security, performance, code quality and testing, internationalization, localization, frameworks and editors and tooling.

The glossary then includes other disciplines of interest and relevance to the modern developer, like computer science, design, typography, usability and user experience, information and project management and more.

It goes beyond web development to feed all your curiosity, about the Web and the technologies and processes used to build it. And still it is a glossary, of several thousand terms for developers, based on careful research as well as established sources, like Wikipedia, but also MDN Web Docs.

This new edition of The Web Development Glossary includes almost a thousand additional terms as well as major usability updates, like improved source and cross-reference navigation.

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.

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

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

Are you unsure about your style sheets’ quality, or whether you’ve maxed out your options? CSS Optimization Basics covers the necessary mindsets, discusses the main optimization methods, and presents useful resources to write higher-quality CSS.

→ This is the book if you care about the craft of writing CSS, and enjoy optimizing style sheets.
