Basic HTML
Basic HTML, or Hypertext Markup Language, is the foundation of web development. It structures content using tags enclosed in angle brackets. Essential tags include <html> for defining the document type, <head> for metadata, and <body> for visible content. Text is formatted using tags like <p> for paragraphs and <h1> to <h6> for headings. Links are created with <a> tags, images with <img>, and lists with <ul> (unordered) and <ol> (ordered). Attributes within tags provide additional information, like src for image sources. HTML provides the structural framework for web pages, laying the groundwork for more complex designs and interactions through CSS and JavaScript.
