📄 HTML Basics

Tags Are Labels in Angle Brackets

HTML (HyperText Markup Language) uses tags to give meaning to content. A tag is written inside angle brackets: <p>. Most tags need both an opening and a closing tag — the closing tag has a forward slash: </p>. Content goes between them: <p>Hello!</p>.

Core Tags to Know

• <h1>–<h6> — Headings, largest to smallest
• <p> — Paragraph of body text
• <a href="URL"> — Hyperlink (clickable text)
• <ul> / <ol> / <li> — Unordered or ordered list with items
• <img src="URL" alt="text"> — Image (self-closing, no end tag needed)
• <strong> — Bold (important) text
• <em> — Italic (emphasized) text

Attributes Add Extra Information

Attributes go inside the opening tag as name="value" pairs. The href attribute in <a href="https://okstem.org"> sets where the link goes. The src and alt attributes in <img> set the image source and its text description for accessibility.
