How to Specify the Relative Path to a CSS File

When importing a CSS file into a web application, it's crucial to specify the correct relative path. In your case, the HTML page is located at localhost:8080/ServletApp/index.html, indicating that your project root is "/ServletApp".

Absolute vs. Relative Paths

• Absolute: Uses a leading slash (/) to indicate the root of the hostname (e.g., "/css/styles.css")
• Relative: Does not use a leading slash, assuming the file is in the same directory as the HTML page (e.g., "css/styles.css")

Your Specific Scenario

Based on your project structure and desired URL, you have two options for the CSS import statement:

• Option 1 (Absolute Path):

<link rel="stylesheet" type="text/css" href="/ServletApp/css/styles.css">

This method is more concrete and ensures that the file is correctly referenced regardless of the location of your other files. However, if you ever plan to remove the "/ServletApp" portion of the URL, you'll need to update the CSS import.

• Option 2 (Relative Path):

<link rel="stylesheet" type="text/css" href="css/styles.css">

This option assumes that the CSS file is always located in the same directory as the HTML page. It's a shorter and cleaner approach, but it requires you to keep the file in this specific location. Additionally, if you ever decide to remove the "/ServletApp" portion of the URL, this import statement will still work as intended.
