<title> | Sets the title of the webpage, displayed in the browser. |
<body> | Contains the content of the webpage that is visible to users. |
HTML Elements and Tags
HTML comprises various elements that define different types of content. Here are some essential elements:
Headings
Headings are used to define the hierarchy of content. There are six levels of headings, from <h1> (largest) to <h6> (smallest).
htmlCopy
<h1>This is a Heading 1</h1>
<h2>This is a Heading 2</h2>
<h3>This is a Heading 3</h3>
Paragraphs
Use the <p> tag to create paragraphs of text.
htmlCopy
<p>This is a paragraph of text that provides information about a topic.</p>
Links
Links allow users to navigate from one page to another. Use the <a> tag with the href attribute to create links.
htmlCopy
<a href="https://www.example.com">Visit Example</a>
Images
Images can be embedded in a webpage using the <img> tag, with the src attribute specifying the image source.
htmlCopy
<img src="image.jpg" alt="Description of image">
Lists
HTML supports both ordered lists (<ol>) and unordered lists (<ul>).
| List Type | Example Code |
|---|---|
| Unordered List | <ul><li>Item 1</li><li>Item 2</li></ul> |
| Ordered List | <ol><li>First Item</li><li>Second Item</li></ol> |
Tables
Tables are created using the <table> element, with rows defined by <tr> and cells by <td>.
htmlCopy
<table>
<tr>
<th>Header 1</th>
<th>Header 2</th>
</tr>
<tr>
<td>Data 1</td>
<td>Data 2</td>
</tr>
</table>
Attributes
Attributes provide additional information about HTML elements. They are specified in the opening tag and usually come in name/value pairs.
| Common Attributes | Description |
|---|---|
href | Specifies the URL for links. |
src | Specifies the path to the image. |
alt | Provides alternative text for images. |
title | Provides additional information. |
Example:
htmlCopy
<a href="https://www.example.com" title="Go to Example">Visit Example</a>
Forms and Input Elements
Forms allow users to submit data to a server. The <form> element is used to create forms, and various input types can be utilized.
Basic Form Structure:
htmlCopy
<form action="/submit" method="post">
<label for="name">Name:</label>
<input type="text" id="name" name="name"><br>
<label for="email">Email:</label>
<input type="email" id="email" name="email"><br>
<input type="submit" value="Submit">
</form>
Common Input Types:

email | A field for entering an email. |
password | A field for entering a password. |
checkbox | A checkbox input. |
radio | A radio button input. |

Semantic HTML
Semantic HTML uses HTML markup to reinforce the meaning of the content. It helps search engines and assistive technologies understand the structure of your web pages.
Examples of Semantic Elements:
| Element | Description |

<header> | Represents introductory content. |
<nav> | Contains navigation links. |
<article> | Represents a self-contained piece of content. |
