Introduction to Relative URLs
In the world of the internet, we often hear the term “web address” or “browser” being used. But have you ever wondered what a relative URL is and how it plays a crucial role on websites? Let’s dive into the basics of relative URLs to understand their significance.
What Is A URL?
Simply put, a URL is like a web address you type into your browser when you want to go to a specific website. It acts as a set of directions that guides your browser to the correct webpage on the internet.
Basics of Relative URLs
When it comes to navigating websites, there are two types of URLs: absolute URLs and relative URLs. Relative URLs are like giving directions to a place using landmarks in the neighborhood, while absolute URLs are like using GPS coordinates. Relative URLs are handy when you want to move around within the same website easily.
How Relative URLs Work
Relative URLs play a crucial role in linking various parts of a website together. They are like signposts that help us navigate from one place to another within the same website.
Linking to Other Pages
Imagine you are on a webpage and want to go to another page on the same website. Relative URLs show the path to get there. They tell the browser to look in a specific folder or directory to find the page you want. It’s like giving directions to a friend to find a hidden treasure in a big park.
Images And Files
Relative URLs aren’t just for linking pages. They also help display images or other files stored on the same website. By providing the right path, relative URLs guide the browser to show the image on the webpage. It’s like telling a story with pictures, where each relative URL leads to a different scene in the tale.
Why Use Relative URLs?
Relative URLs are a fundamental aspect of web development that offers several advantages, making them a popular choice for many developers. Let’s delve into the reasons why using relative URLs can simplify your web development process.

Easy to Move Things Around
One of the primary benefits of using relative URLs is that they make it effortless to move files and directories within your website without causing broken links. When you use relative URLs, the links are specified in relation to the current page, allowing you to rearrange your files and folders without having to update each link individually. This flexibility saves time and minimizes errors that can occur when shifting web elements.
Shorter And Simpler
Relative URLs are concise and straightforward, as they only require a portion of the complete web address. Unlike absolute URLs that contain the entire path starting from the domain, relative URLs only specify the location of the resource in relation to the current page. This brevity not only makes the URLs easier to manage but also enhances the readability of your code, contributing to a more organized and efficient web development process.
Examples of Relative URLs
Let’s say you have a website with two pages, “home.html” and “about.html”. If you want to make a link on the home page to the about page, you can use a relative URL like this:
<a href="about.html">About Us</a>
Image Source Example
Images on a website can also use relative URLs. If you have an image called “logo.png” in a folder named “images”, you can display it with a relative URL like this:
<img src="images/logo.png" alt="Logo">
Relative URLs vs. Absolute URLs
An absolute URL is the complete web address that includes the protocol (like https://), the domain name (such as www.example.com), and the specific page or file path. It provides the full path to a resource on the internet.

Key Differences
Now, let’s talk about the key differences between relative URLs and absolute URLs. Imagine you are giving directions to a friend to find a hidden treasure. Relative URLs would be like telling your friend to take three steps forward and turn left, while absolute URLs would be like giving them the exact GPS coordinates to the treasure.
Common Mistakes with Relative URLs
One of the common mistakes people make when using relative URLs is ending up with broken links. This happens when the path specified in the URL is incorrect or leads to a non-existent page on the website. For example, if you link to a page using a relative URL but you mistype the path, the browser won’t be able to find the page, resulting in a broken link. To fix this issue, always double-check the paths you use in your relative URLs to ensure they lead to the intended pages.
Confusing Paths
Another frequent mistake is confusing the paths in relative URLs, which can point to the wrong location on a website. Imagine trying to link to an image on your website, but mistakenly providing an incorrect file path. This can display a different image or even an error message instead of the intended picture. To avoid this error, make sure you understand the folder structure of your website and accurately specify the paths in your relative URLs to direct users to the right content.
How To Write Relative URLs
When creating links on a website, it’s essential to write relative URLs correctly to ensure they function properly. Follow these simple steps to master the art of writing relative URLs.

Using Folders
One way to write a relative URL is by using folders to navigate to the desired page on a website. Imagine a website as a filing cabinet, with each folder representing a different section. To link from one page to another in the same folder, you can simply use the file name as the relative URL.
For example, if you have a page about cats stored in a folder called “animals” and want to link to a page about dogs in the same folder, your relative URL would look like this: <a href="dogs.html">Click here to learn about dogs</a>.
Step-by-Step Examples
Let’s walk through a step-by-step example of writing a relative URL. Suppose you have a website with the following structure:
- Main folder: “website”
- Subfolders: “pages” and “images”
- Files: “index.html”, “about.html”, “contact.html”, “logo.png”
To link from the “index.html” page to the “about.html” page located in the “pages” folder, you would write the following relative URL:
<a href="pages/about.html">About Us</a>
Similarly, if you want to display an image called “logo.png” on the “index.html” page from the “images” folder, your relative URL for the image would be:
<img src="images/logo.png" alt="Company Logo">
Following these simple steps and using clear folder paths will help you write accurate and functional relative URLs throughout your website.
Conclusion
In conclusion, relative URLs play a crucial role in web development by simplifying the way web pages and files are linked within a website. Understanding how relative URLs work can make managing a website easier and more efficient.
Throughout this blog post, we learned that a URL is like an address you type into your browser to visit a website. Relative URLs, unlike absolute URLs, only need to specify the path or location of a resource within the same website without including the entire web address.
By using relative URLs, web developers can easily move pages and files around without breaking links, making maintenance and updates simpler. Additionally, the shorter and more straightforward nature of relative URLs makes them easier to work with compared to absolute URLs.
It’s essential for anyone working on a website or learning web development to grasp the concept of relative URLs and how they function. By following the guidelines outlined in this blog post, you can ensure that your website’s links function correctly and efficiently.
Frequently Asked Questions (FAQs)
What is the difference between a relative URL and an absolute URL?
A relative URL is a type of web address that specifies the location of a resource in relation to the current page, while an absolute URL provides the complete web address starting from the domain name. In simpler terms, a relative URL tells the browser where to find a resource within the same website, while an absolute URL includes the full web address, including the domain name.
Can relative URLs work for external websites?
No, relative URLs are designed to work within the same website’s structure and cannot be used to link to external websites. When linking to a resource on a different website, an absolute URL must be used to provide the complete path to that specific resource.
How do I know if my URL is relative?
To determine if a URL is relative, you can check if the address provided is just a path to a specific resource on the same website without including the full web address starting from the domain name. Relative URLs typically do not include https://www.example.com in their address and instead start with /folder/page.html.
