HTML base tag
The HTML base tag, although relatively simple, is a pivotal element in web development. It specifies a base URL to be used for relative URLs within a document. In simpler terms, it helps define the base URL for resources like images, stylesheets, and links on a webpage. By providing a base URL, web developers can streamline the management of assets and ensure consistent link behaviors throughout their websites.
In the below PDF we discuss about HTML Base Tag in detail in simple language, Hope this will help in better understanding.
Syntax of the HTML Base Tag:
The HTML <base> tag is quite straightforward to use. It’s placed within the <head> section of your HTML document, where you can set the base URL as the href attribute. Here’s the basic syntax:
<!DOCTYPE html>
<html>
<head>
<base href="https://example.com/">
<!-- Other head elements, such as title, meta tags, etc. -->
</head>
<body>
<!-- Your webpage content -->
</body>
</html>
In the example above, we’ve set the base URL to “https://topperworld.in/”. Now, any relative URLs used within the document will be resolved based on this base URL.
Applications of the HTML Base Tag:
1. Simplifying Relative URLs
The most common use of the <base> tag is to simplify the management of relative URLs. Consider a scenario where you have multiple web pages within the same domain, and they all reference the same CSS file and images. Instead of specifying the full URL for every asset, you can set the base URL in the document’s head, making it easier to maintain and update. Here’s an example:
<!DOCTYPE html>
<html>
<head>
<base href="https://example.com/">
<link rel="stylesheet" href="css/styles.css">
</head>
<body>
<img src="images/logo.png" alt="Website Logo">
</body>
</html>
With the <base> tag set, the browser knows to look for the stylesheet and image in the “https://topperworld.in/” directory, saving you from having to specify the complete path each time.
2. Cross-Origin Resource Management
In some cases, web developers need to load resources from different domains or subdomains. The <base> tag can be useful for managing cross-origin resources by specifying the base URL of a different domain, ensuring proper resource loading

The HTML base tag is used to specify a base URL for relative URLs within a web page. It provides a reference point for resolving relative links, such as those in anchor elements or script sources.
The base tag is important because it helps maintain consistency in relative URLs throughout a website. It allows you to set a common base URL, making it easier to manage links and resources, especially when your website has a complex directory structure.
When the base tag is set, all relative URLs on the page are resolved in relation to the specified base URL. This means that if you have links or references to external resources without an absolute URL, the browser will automatically prepend the base URL to those links.
No, you should have only one base tag per HTML document. If you include multiple base tags, the last one encountered in the document is the one that takes effect.
