HTML stands for Hypertext Markup Language. It is the standard markup language used for creating web pages and web applications. HTML uses a set of markup tags to structure the content and define the layout of a web page.
Here are some key points about HTML:
Structure: HTML provides a way to organize content on a web page using a hierarchical structure. Elements are defined using opening and closing tags, and they can be nested within each other to create a structure.
Tags: HTML tags are used to mark up different parts of the content. Tags are enclosed in angle brackets (< >). The opening tag denotes the start of an element, and the closing tag denotes the end. Some tags are self-closing and do not require a closing tag.
Elements: HTML elements are defined by tags and can include text, images, links, tables, forms, and more. They represent different types of content and define the structure of a web page.
Document Structure: An HTML document typically starts with a document type declaration (<!DOCTYPE html>) to indicate that it follows the HTML5 standard. The <html> element is the root element of the document and contains the entire HTML content. It is usually followed by the <head> and <body> elements.
Styling and Formatting: HTML provides various tags to apply formatting and styling to the content, such as headings (<h1> to <h6>), paragraphs (<p>), lists (<ul>, <ol>, <li>), and more. However, for advanced styling, CSS (Cascading Style Sheets) is typically used.
Links and Images: HTML enables the inclusion of hyperlinks using the <a> tag, allowing users to navigate between different web pages. Images can be inserted using the <img> tag, specifying the image source URL, alt text, and other attributes.
Forms and Input: HTML provides form elements like <form>, <input>, <select>, <textarea>, etc., which allow users to enter and submit data. Forms are commonly used for user interactions, such as submitting information or performing searches.
Accessibility: HTML has built-in features and guidelines to improve web accessibility, making it easier for people with disabilities to access and navigate web content. These include semantic tags, alternative text for images, proper use of headings, and more.
HTML is the foundation of the web and is often combined with CSS and JavaScript to create interactive and visually appealing websites and web applications.
In the example above:
<html> is the root element and encloses the entire HTML document.
<head> contains meta-information about the document, such as the page title specified within the <title> tag.
<body> contains the visible content of the web page, such as headings, paragraphs, images, and links.
<h1> is a heading level 1, denoting the main heading of the page.
<p> represents a paragraph of text.
<img> inserts an image into the page, with the image file specified by the src attribute and the alternative text provided by the alt attribute.
<a> creates a hyperlink to another webpage, with the URL specified by the href attribute.
HTML provides a way to structure content semantically, enabling web browsers and other tools to interpret the document correctly and present it to users in a meaningful way. It is the backbone of the web and is often used in conjunction with CSS (Cascading Style Sheets) and JavaScript to create interactive and visually appealing web pages
