HTML5

The current standard version of HTML, the markup language that structures every web page’s actual content — headings, paragraphs, images, forms, and the semantic elements that describe what each part of a page is.

Semantic elements (proper headings, nav, article, and so on) tell browsers, search engines, and assistive technology what each part of a page actually is, rather than a wall of generic, meaningless divs.

It’s the foundation modern design is built on — native video and audio, better form elements, and semantic structure without needing extra plugins or workarounds that older HTML versions required.

Directly — screen readers and other assistive technology rely heavily on semantic HTML5 elements and proper structure to make sense of a page for someone who can’t see the visual layout.

No — content editing happens through WordPress’s normal editor, which generates the HTML behind the scenes. It matters for how the theme itself is built, not for day-to-day content work.

Yes — proper heading structure, meaningful markup, and clear document outline are things search engines (and increasingly AI systems) use to understand what a page is actually about.

Essentially universally at this point — it’s been the standard for years, and browser support isn’t a practical concern for a modern build.

Built-in input types (email, phone, date, and so on) with native browser validation — less custom code needed, and better mobile keyboards shown automatically for the right field type.

Well-structured, lean markup loads and renders faster than bloated, deeply-nested markup a page builder often generates — another quiet advantage of a hand-built theme over a generic one.

Semantic HTML5 elements pair naturally with structured data, helping search engines and AI tools understand not just that content exists, but specifically what kind of content it is.
