HTML stands for Hypertext Markup Language. It is a standard markup language for creating web pages and applications. HTML is used to structure a webpage's content and specify how that content should be displayed in a web browser.
An HTML document is a text file that contains small markup tags. These tags tell the web browser how to format and display the webpage's content. For example, the <h1> tag is used to display a heading, the <p> tag is used to display a paragraph, and the <img> tag is used to display an image.
Here is a simple example of an HTML document:
<!DOCTYPE html>
<html>
<head>
<title>My Webpage</title>
</head>
<body>
<h1>Welcome to my webpage</h1>
<p>This is my first webpage. I hope you enjoy it!</p>
<img src="my-image.jpg" alt="A picture of me">
</body>
</html>
In this example, the <!DOCTYPE html> declaration specifies that the document is an HTML5 document. The <html> element is the root element of the HTML document, and it contains the <head> and <body> elements. The <head> element contains metadata about the document, such as the title, and the <body> element contains the webpage's content.
There are many more HTML tags that you can use to structure and format your web pages. To learn more about HTML, you can refer to online tutorials and resources, such as the HTML documentation on the W3C website (https://www.w3.org/TR/html/).
