HTML (Hypertext Markup Language) is a standard markup language used for creating web pages and web applications. It provides the structure and content of a webpage, defining how elements should be displayed in a browser. HTML uses a series of tags to define and organize different elements on a webpage, such as headings, paragraphs, images, links, forms, tables, and more.
Here's a brief introduction to HTML programming language:
1. Structure: HTML documents are composed of nested elements enclosed in tags. An HTML document typically begins with a doctype declaration, followed by an opening `<html>` tag. The `<head>` section contains meta information about the document, while the `<body>` section holds the visible content.
2. Tags: HTML tags are used to define different elements. They are enclosed in angle brackets ("<" and ">"). Tags often come in pairs, with an opening tag ("<tag>") and a closing tag ("</tag>"). For example, `<h1>` is the opening tag for a heading, and `</h1>` is the closing tag. Some tags, called self-closing tags, don't require a closing tag, such as `<img>` for an image.
3. Attributes: Tags can have attributes to provide additional information or modify the behavior of an element. Attributes are placed within the opening tag and consist of a name and a value. For example, the `<img>` tag has an attribute called `src` to specify the image source: `<img src="image.jpg">`.
4. Text Content: HTML can include text content directly between the opening and closing tags of an element. For example, `<p>This is a paragraph.</p>` represents a paragraph element containing the text "This is a paragraph."
5. Links and URLs: HTML enables the creation of hyperlinks using the `<a>` (anchor) tag. The `href` attribute specifies the destination URL: `<a href="https://example.com">Link</a>`.
6. Images: Images can be displayed using the `<img>` tag. The `src` attribute defines the image source, and the `alt` attribute provides alternative text that is displayed if the image fails to load: `<img src="image.jpg" alt="Description">`.
7. Lists: HTML supports both ordered lists (`<ol>`) and unordered lists (`<ul>`). List items are represented by the `<li>` tag. For example:
8. Forms: HTML provides elements to create forms for user input. The `<form>` tag encapsulates form elements such as `<input>`, `<textarea>`, and `<select>`. Form data can be submitted to a server for processing.
9. CSS Styling: HTML can be styled using CSS (Cascading Style Sheets). CSS rules define the visual appearance of HTML elements, including colors, fonts, layouts, and more.
HTML is the backbone of web development and is often combined with CSS and JavaScript to create interactive and visually appealing websites and web applications. By mastering HTML, you can structure and present information effectively on the web.
All HTML documents must start with a document type declaration: <!DOCTYPE html>.
The HTML document itself begins with <html> and ends with </html>.
The visible part of the HTML document is between <body> and </body>
The <!DOCTYPE> Declaration
The <!DOCTYPE> declaration represents the document type and helps browsers display web pages correctly.
It must only appear once, at the top of the page (before any HTML tags).
The <!DOCTYPE> declaration is not case-sensitive.
The <!DOCTYPE> declaration for HTML5 is:
HTML headings are defined with the <h1> to <h6> tags.
<h1> defines the most important heading. <h6> defines the least important heading:
