HTML , CSS , and JavaScript Fundamentals
HTML: Structuring the Web
HTML (HyperText Markup Language) is the backbone of any website. It offers the structure and text of web pages. Think of it as the skeleton upon which everything else is built. Without HTML , there would be no text , images , or links. Learning HTML involves understanding various tags and elements that define varied parts of a webpage. For example , the
tag is used for paragraphs ,
to
tags are used for headings , and ![]()
tag is used for embedding images.
To get started with HTML , you should focus on the following:

- Lists: Creating ordered (
- Links: Creating hyperlinks using the
tag.
- Images: Embedding images using the
tag. - Tables: Creating tables using the
,
, , and tags. - Forms: Building forms using the
,
,
, and
tags.
Example:
