HTML & CSS
This chapter works through HTML and CSS Essentials, the anchor topic behind HTML & CSS Foundations.
Every element has an opening tag, optional content, and a closing tag.
Understand how an HTML document is organized, how the <head> and <body> interact, and where CSS fits into the structure.
Headings, paragraphs, emphasis, and inline semantics give structure and meaning to your text.
Lists group related items; tables display structured data.
Links connect your site together.
Add images, audio, and video to enrich your pages.
Forms collect user input.
Components are reusable chunks of markup and styles-cards, buttons, banners-that keep your design consistent and speed up development.
