Practical 4: Creating Links
Objective:
To learn how to create hyperlinks (links) in HTML to connect different web pages or resources.
Instructions:
Open your index.html file created in Previous Lab .
Add a hyperlink inside the <body> tag:
<body>
<h1>Welcome to My First HTML Page</h1>
<p>This is a paragraph of text.</p>
<a href="https://www.example.com">Visit Example.com</a>
</body>
Save and view your HTML document in a web browser to see the link.
Detailed Explanation:
Creating a Hyperlink:
HTML Anchor <a> Tag:
The <a> tag (anchor tag) is used to create hyperlinks in HTML.
Syntax: <a href="URL">Link Text</a>
href: Specifies the URL (web address) to which the link points.
Link Text: Text displayed as the clickable link.
Example:
<a href="https://www.example.com">Visit Example.com</a>
This creates a hyperlink labeled "Visit Example.com" that, when clicked, navigates the browser to https://www.example.com.
Relative vs. Absolute URLs:
Absolute URL:
Directly points to a specific web address, starting with http:// or https://.
Example: <a href="https://www.example.com">Visit Example.com</a>
Relative URL:
Points to a resource relative to the current location or file.
Example: <a href="about.html">About Us</a>
Links to a file named about.html in the same directory as the current HTML file.
Linking to Sections within a Page:
Internal Linking:
Use the id attribute and the # symbol to link to specific sections within the same page.
Example:
<a href="#section1">Jump to Section 1</a>
...
<h2 id="section1">Section 1</h2>
Clicking "Jump to Section 1" navigates the browser to the section with id="section1" on the same page.
Linking to Email Addresses:
Email Link:
Use the mailto: protocol to create a link that opens the user's default email program with a specified email address.
Example:
<a href="mailto:info@example.com">Email Us</a>
Clicking "Email Us" opens the default email client with info@example.com pre-filled in the "To" field.
Outcome:
By completing this lab, you will understand how to create various types of hyperlinks in HTML, including links to external websites, internal sections within a page, and email addresses. This knowledge is essential for building interconnected web pages and providing navigation options for users.

Objective:
To practice creating different types of hyperlinks using <a> tag in HTML.
Instructions:

</html>
Save the file and open it in a web browser to view your web page (creating_links.html).
Detailed Explanation:
HTML Structure:
- <a> (Anchor) Tag: Defines a hyperlink that links to another page or location within the same page.
- href="https://www.example.com": Specifies the URL of the destination page (external link to Example.com).
- href="#services": Links to a specific section within the same page using the id attribute (<h2 id="services">Services</h2>).
- href="documents/report.pdf" download: Links to a downloadable file (report.pdf) with the download attribute to prompt the user to save the file.
Linking to Sections:
- <a href="#web-design">Web Design</a>: Links to the <h3 id="web-design">Web Design</h3> section within the same page.
Additional Tips:
- External Links: Use absolute URLs (https://www.example.com) to link to external websites.
- Internal Links: Use relative URLs (#services, documents/report.pdf) to link within the same page or to files in the same directory or subdirectories.
- Downloadable Files: Use the download attribute with <a> tags to make files downloadable (<a href="file.pdf" download>).
Tasks:
Enhance your page by:
- Adding more hyperlinks to external websites, other sections within the same page (#services, #web-design, etc.), and downloadable files.
- Experimenting with different link text (<a> content) and URL formats (absolute and relative URLs).
Practice linking to sections:
Create new sections (<h3>) and link to them from a navigation list (<ul>).
Outcome:
By completing this lab exercise, you will have practiced creating different types of hyperlinks in HTML, including links to external websites, internal sections within the same page, and downloadable files. This exercise helps you understand the versatility of <a> tags and prepares you for integrating navigation and content linking in your web development projects effectively.
