1、Understanding HTML:
HTML (Hypertext Markup Language) is the foundation of any website. It provides the structure and content of web pages. To begin our journey, let's explore the basics of HTML.
1、1 HTML Structure:
HTML documents consist of a set of tags that define the structure of the web page. The basic structure includes the<!DOCTYPE html> declaration, the<html> element, the<head> element, and the<body> element. The<head> section contains metadata, such as the title of the page and links to CSS files, while the<body> section contains the visible content.
1、2 HTML Tags:
HTML tags are used to define elements on a web page. For example, the<h1> tag is used for headings, the<p> tag is used for paragraphs, and the<a> tag is used for hyperlinks. Understanding these tags is crucial for building a well-structured website.
1、3 HTML5:
HTML5 is the latest version of HTML and introduces new elements and features. Familiarize yourself with HTML5 elements such as<header>,<footer>,<nav>, and<section>, which help in creating semantic and accessible web pages.
2、CSS: Styling the Website:
CSS (Cascading Style Sheets) is used to style the HTML elements and make the website visually appealing. Let's explore the basics of CSS.

The CSS box model describes the layout of HTML elements. It includes properties such asmargin,padding,border, andwidth, which determine the size and position of elements on the page.
3、JavaScript: Adding Interactivity:
JavaScript is a programming language that adds interactivity to web pages. Let's explore the basics of JavaScript.
3、1 JavaScript Variables and Data Types:
JavaScript variables are used to store data, and data types determine the kind of data a variable can hold. Common data types include strings, numbers, and booleans.
3、2 JavaScript Functions:
Functions in JavaScript allow you to define reusable blocks of code. By creating functions, you can perform specific tasks and enhance the interactivity of your website.
