A hyperlink in HTML is a clickable element on a webpage that directs users to another resource, such as another page, a different location within the same page, or even an external file. It acts as a bridge, allowing navigation and interaction on the web.
Understanding the <a> Tag
The core of a hyperlink in HTML is the <a> tag, also known as the anchor tag. This tag is used to create the link itself. The most vital attribute within this tag is href, which specifies the destination of the link.
Key Attributes
| Attribute | Description | Example |
|---|---|---|
href |
Specifies the URL of the page the link goes to. | <a href="https://www.example.com">Visit Example</a> |
target |
Specifies where to open the linked document. Common values include _blank (new tab), _self (same tab, default), _parent, and _top. |
<a href="https://www.example.com" target="_blank">Visit Example</a> |
How Links Appear by Default
As stated in the reference, by default, web browsers typically display links in a distinctive way:
- An unvisited link is underlined and blue.
- A visited link is underlined and purple.
- An active link (when you click on it) is underlined and red.
These styles can be changed using CSS.

Practical Insights
- User Experience: Use clear and concise link text. Avoid "click here" and instead use descriptive text that explains where the link will lead the user.
- SEO: Descriptive and keyword-rich link text can also help with search engine optimization.
- Accessibility: Make sure your links are easily distinguishable, especially for users with visual impairments. CSS can be used to adjust their visual appearance.
Example of a Basic Link
<a href="https://www.example.com">This is a link to Example.com</a>This code creates a link that says "This is a link to Example.com" and, when clicked, takes the user to https://www.example.com.
