With ever-changing devices, browsers, operating systems, form factors, specifications, personal preferences, tooling, and corporate interests, the web is in a constant state of flux. As a result, so is the HTML we write. For every line of the HTML specification itself that has changed since the language’s inception, there are many more bits of HTML that have seen what I’ll call ‘environmental’ changes. Adaptations to differing browsers, extensions, integrations, and systems which we find HTML existing in.
This article doesn’t cover once-specced but now obsolete bits of HTML but instead looks at all the snippets that have wormed their way into websites as result of, or in combat against, third-party integrations, browser competition, vendor extensions, and platform-specific hacks. The bits of HTML that were included for reasons, and which have been forgotten for present irrelevance. The snippets that live on only in the markup of sites from bygone eras and in the minds of those who fought during the browser wars.
