🔗 Lost, forgotten, and unfamiliar HTML

In a recent exploration of HTML, Dave Iverson uncovered many overlooked aspects of building a website. His experiments with HTML-validate and Axe core highlighted crucial points, such as the case sensitivity of data attributes in HTML, where all attribute names should be lowercase. He discovered the nuances of id attributes, which can now include emojis and must be unique, but with specific rules for HTML4 and HTML5.

Iverson emphasized the importance of redundant for attributes, correcting invalid aria-label usages, and ensuring all iFrames have unique titles for accessibility. He also addressed color contrast issues detected by scanning tools, keyboard support for scrolling regions, and proper labeling of SVGs. His insights remind developers to pay close attention to these often-forgotten details, ensuring better accessibility and user experience across websites.
