Certainly! Let me provide explanations for each HTML element and attribute included in the extended cheat sheet:

1. Headings:

   <h4>This is a Heading 4</h4>
   <h5>This is a Heading 5</h5>
   <h6>This is a Heading 6</h6>

Headings are used to define headings in HTML. They range from <h1> (largest) to <h6> (smallest).

2. Paragraph Formatting:

   <p><strong>Bold Text</strong></p>
   <p><em>Italic Text</em></p>
   <p><u>Underlined Text</u></p>

HTML provides tags like <strong>, <em>, and <u> for emphasizing text in different ways.

3. Line Break:

   <p>This is<br> a line break</p>

The <br> tag is used to insert a line break within text.

4. Horizontal Line:

   <hr>

<hr> creates a thematic break or horizontal line.

5. Links with Target:

   <a href="https://www.example.com" target="_blank">Open in a new tab</a>

The target="_blank" attribute opens the link in a new browser tab.

6. Lists with Descriptions:

   <dl>
     <dt>HTML</dt>
     <dd>HyperText Markup Language</dd>
     <dt>CSS</dt>
     <dd>Cascading Style Sheets</dd>
   </dl>

<dl> is used for description lists, where <dt> is a term and <dd> is its description.

7. Ordered List Types:

   <ol type="A">
     <li>Item A</li>
     <li>Item B</li>
   </ol>

The type attribute allows you to specify the type of ordered list (A, a, I, i).

8. Images with Width and Height:

   <img src="image.jpg" alt="Description" width="300" height="200">

<img> is used to embed images. The width and height attributes set the dimensions.

9. Form Input Types:

   <input type="text" placeholder="Text Input">
   <input type="checkbox" id="checkbox"> <label for="checkbox">Checkbox</label>
   <input type="radio" id="radio" name="radio"> <label for="radio">Radio Button</label>

Various input types (text, checkbox, radio) for form elements.

10. Textarea:

   <textarea rows="4" cols="50" placeholder="Enter text here..."></textarea>

<textarea> creates a multiline text input field.

11. Select Dropdown:

   <select>
     <option value="option1">Option 1</option>
     <option value="option2">Option 2</option>
   </select>

<select> creates a dropdown list, and <option> defines the options within the list.

12. Table with Caption:

   <table>
     <caption>Table Caption</caption>
     <thead>
       <tr>
         <th>Header 1</th>
         <th>Header 2</th>
       </tr>
     </thead>
     <tbody>
       <tr>
         <td>Row 1, Cell 1</td>
         <td>Row 1, Cell 2</td>
       </tr>
     </tbody>
   </table>

<table> is used to create a table, and <caption> provides a title for the table.

13. Span for Inline Styling:

   <p>This is <span style="color: red;">red</span> text.</p>

<span> is used for inline styling. In this example, it changes the text color to red.

14. HTML Entities:

HTML entities like © (copyright) and ® (registered trademark) represent special characters.
