目录

HTML 简介

HTML, or HyperText Markup Language, is the standard markup language for creating web pages. It describes the structure of a web page semantically and originally included cues for presentation, such as boldness, italics, and alignment, but now it only provides the structure.

Here's an example of a simple HTML page:

<!DOCTYPE html>
<html>
<head>
  <title>My First Web Page</title>
</head>
<body>
  <h1>Hello, World!</h1>
  <p>This is my first HTML page.</p>
</body>
</html>

CSS 入门

CSS, or Cascading Style Sheets, is a style sheet language used for describing the presentation of a document written in HTML or XML. CSS describes how HTML elements are to be displayed on screen, in print, or on other media.

Here's a basic CSS example:

body {
  background-color: #f0f0f0;
  font-family: Arial, sans-serif;
}

h1 {
  color: #333;
}

JavaScript 初探

JavaScript is a programming language that enables you to create interactive web pages. It is the world's most popular programming language for web development.

Here's a simple JavaScript example:

console.log("Hello, World!");

Responsive design is a design approach aimed at crafting sites to provide an optimal viewing experience—easy reading and navigation with a minimum of resizing, panning, and scrolling—across a wide range of devices (from mobile phones to desktop computer monitors).

Here's an example of a responsive design pattern:
