Unlocking HTML: Your Guide to Understanding Web Basics
Understanding HTML Basics
HTML, or HyperText Markup Language, is the standard language used to create web pages. HTML is not a programming language, but a markup language. It instructs web browsers on how to format and display the content. HTML uses tags to define elements like headings, paragraphs, links, and images.
The Structure of an HTML Document
An HTML document begins with a declaration indicating that this is an HTML5 document. The document includes two sections: the head section, inside “ tags, and the body section, within “ tags. The head usually contains meta-information about the document, such as its title. The body contains the main content. See below:

The `` tag is used to embed images in an HTML page. Images are not technically inside the HTML file, but are linked using the “src” attribute. Alternate text can be provided using the ‘alt’ attribute: ``.
