What Is HTML ?
HTML (Hypertext Markup Language) is the standard language used to create and design web pages. The <details> element in HTML is used to create a disclosure widget, which allows users to show or hide additional information. It's often used to create collapsible sections of content on a webpage. Here's how it works:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Details Example</title>
</head>
<body>
<!-- Example of using the <details> element -->
<details>
<summary>Click to expand</summary>
<p>This is the additional information that will be shown when the disclosure widget is expanded.</p>
</details>
</body>
</html>
What is tag?
In HTML, a "tag" refers to the markup element used to define the structure and content of a web page. Tags are enclosed in angle brackets < > and typically come in pairs: an opening tag and a closing tag. The opening tag contains the name of the element, while the closing tag has the same name preceded by a forward slash /.
For example:
<p>This is a paragraph.</p>
In this example:
<p> is the opening tag, which defines the beginning of a paragraph.
</p> is the closing tag, which defines the end of the paragraph.
Some HTML elements don't require closing tags, such as the <img> tag for embedding images or the <br> tag for line breaks. These are called "void" or "empty" elements.
