HTML
Quick Definition
HTML (HyperText Markup Language) is the standard language that defines the structure of every web page — headings, paragraphs, links, images, and lists. WordPress generates HTML automatically from your content, but understanding basics helps you customize and troubleshoot.

What Is HTML?
HTML defines structure and content of web pages. CSS = appearance, HTML = structure. WordPress block editor generates HTML automatically — heading blocks create <h2>, paragraphs create <p>, images create <img>.
How HTML Works
<a href="https://zerotowp.com" target="_blank">Visit ZeroToWP</a>
- Tag — Defines element type
- Attributes — Extra information (href, target)
- Content — What users see
Essential Tags for WordPress Users
| Tag | Creates | WP Block |
|---|---|---|
<h1-h6> | Headings | Heading block |
<p> | Paragraph | Paragraph block |
<a> | Link | Link in any block |
<img> | Image | Image block |
<ul/ol> | Lists | List block |
<div> | Container | Group block |
