HTML, HyperText Markup Language, is the foundational language used to structure content on the web. It defines what a piece of content actually is — a heading, a paragraph, a link, an image — using a system of nested tags, giving every webpage its basic underlying skeleton.
Basic HTML Building Blocks
- Headings (`<h1>` through `<h6>`) — define titles and section headers
- Paragraphs (`<p>`) — hold blocks of regular text
- Links (`<a>`) — create clickable hyperlinks to other pages
- Images (`<img>`) — embed pictures directly into a page
- Lists (`<ul>`, `<ol>`) — create bulleted or numbered lists
HTML's Relationship to CSS and JavaScript
HTML provides pure structure — the content itself and how it's organised. CSS then adds visual styling on top of that structure, and JavaScript adds interactivity. Together, these three form the complete foundation of virtually every webpage on the internet.
Where HTML Shows Up in WordPress
Most WordPress users never write raw HTML directly — the Gutenberg block editor generates it automatically behind the scenes. It becomes directly useful when embedding a custom widget, adding a specific tracking code, or making a fine-grained tweak the block editor's visual controls simply don't offer, via WordPress's dedicated Custom HTML block.
