Short Answer
In HTML, a tag is a piece of code that tells the web browser how to display content. Tags are like labels that give instructions. They come in pairs, including an opening tag and a closing tag. The opening tag starts with < and ends with >, and the closing tag is similar but includes a slash / before the tag name.
There are many types of HTML tags, each serving a different purpose. For example:
<p>for paragraphs makes a block of text.<h1>to<h6>are heading tags, with<h1>being the biggest and<h6>the smallest.<a>creates links to other pages or sites.<img>adds images to your page.<ul>and<ol>make lists, with<ul>for unordered lists and<ol>for ordered lists.<div>and<span>are for grouping and styling sections of content with CSS.
Tags are the basic building blocks of web pages, allowing us to add text, links, images, and structure our content in a way that’s easy for users to navigate and understand.

HTML Tags
An HTML tag is a crucial element in the language of the web. It’s a command that tells a web browser how to format and display the content. Tags are the skeleton of any web page, organizing and controlling every piece of content you see online.

- Structural Tags: These tags define the structure and layout of web pages. Examples include:
<html>: The root element that defines an HTML document.<head>: Contains meta-information about the document.<title>: Specifies the title of the document.<body>: Contains the content of the document that is visible to users.

<h1>,<h2>, …,<h6>: Heading tags that create headings and subheadings.<p>: Defines a paragraph.<b>and<strong>: Make text bold.<i>and<em>: Italicize text, with<em>indicating emphasis.
- Link and Image Tags: These tags are used to insert links and images.
<a href="URL">: Creates a hyperlink.<img src="image_path" alt="text">: Embeds an image.
- List Tags: Useful for creating ordered and unordered lists.
<ul>: Starts an unordered list.<ol>: Begins an ordered list.<li>: Defines a list item.
- Container Tags: These tags don’t affect the content directly but are used to group content.
<div>: Defines a division or section.<span>: Targets inline elements for styling.
- Form Tags: Essential for creating interactive forms.
<form>: Defines a form that can contain inputs, labels, buttons, etc.<input>: Creates input fields for text, radio buttons, checkboxes, and more.<label>: Defines a label for<input>elements.

<h1>This is a Heading</h1>
<p>This is a paragraph.</p>- Here,
<h1>makes a large heading, and<p>creates a block of text.
Adding an Image and a Link:
<img src="logo.png" alt="Website Logo">
<a href="https://www.example.com">Visit Example</a>- The
<img>tag adds an image, and<a>creates a clickable link.
Making a List:
<ul>

</ul>- This code uses
<ul>and<li>to make an unordered list.
