Href in HTML
What is href, and why is it important? href, which stands for "hypertext reference," is a key attribute in HTML that enables navigation on the internet. It is used within an anchor (<a>) tag to define the destination URL that users are directed to when they click a link.
The Structure of Href
A typical anchor tag with an href attribute looks like this:
Html
In this example, clicking "Visit Example" will take you to "https://www.example.com".
Types of Resources Linked by Href
href can link to various types of resources, including:
- A webpage
- An image
- A PDF file
- An email address
For example, to link an email address, you can use:
Html
This will open your default email client with "[email protected]" in the "To" field.
In-Page Navigation
href can also facilitate navigation within the same document. You can link to a specific section using an ID selector:
Html
Clicking "Jump to Section 2" will scroll the page to the <h2> section marked with the ID.
Understanding Relative and Absolute URLs
There are two main types of URLs used with href: absolute and relative.
- Absolute URL: This includes the full path, such as:
Html
- Relative URL: This is based on the current position within a website. For example:
Html
This relative link directs you to "www.example.com/articles/category/science."
Controlling Link Behavior
You can control how a linked resource opens by using the target attribute. The default behavior replaces the current page with the new one. To open a link in a new tab, use:
Html
Href in Other HTML Elements
The href attribute is also used in other HTML elements, such as the link tag in the <head> section, which is used to link CSS files:

In this case, href specifies the path to the stylesheet.
Importance of Href in SEO
Using descriptive links improves user navigation and helps search engines crawl your content more effectively. Clear link structures are beneficial for overall website optimization.
That summarizes the importance and functionality of href. Its simplicity plays a vital role in maintaining the connectivity of the web.
