Let’s talk about how to write HTML page paths

In web development, the HTML page path is a very important concept. It refers to the address of the website page's storage location on the server. HTML page paths can be divided into relative paths and absolute paths. Below we will introduce how to write HTML page paths and the differences and applications of the two methods.

1. Relative path

The relative path is the path pointing to the target file using the current page as a reference. Relative paths are suitable for file references in the same root directory. There is no need for a complete URL and part of the path can be omitted.

Relative path example:

1. Path relative to the current directory: for example, ./ represents the current directory, ../ represents the parent directory, ../../ represents the parent directory the parent directory, and so on.
2. The path relative to the root directory: starts with "/", for example, /images/test.jpg represents the test.jpg file in the images folder in the root directory.
3. Relative to the path in the same level directory: does not start with "/", for example, images/test.jpg represents the test.jpg file in the images folder in the directory at the same level as the current page.

2. Absolute path

The absolute path is the complete path starting from the root directory of the website, including the protocol, domain name, path and other components. The reference of the absolute path will span the entire website, but when the changes are large, they need to be modified one by one, which is inconvenient to maintain.

Absolute path example:

1. URL absolute path: Start with the protocol (http or https), for example, http://www.example.com/images/test.jpg means The test.jpg file in the images folder in the root directory of the website can reference the image or file through the complete URL.
2. Disk absolute path: the complete path starting from the root directory of the disk, for example, C:/wwwroot/images/test.jpg represents the test.jpg file in the images folder under the wwwroot folder on the disk , usually only used for local testing.

Summary

HTML page path is an important concept in web development. Mastering the way to write the path is helpful for planning the website directory and referencing files. Relative paths are suitable for file references in the same root directory, while absolute paths are suitable for file references that span the entire website. In actual website development, adopting the corresponding path method according to the actual situation is beneficial to the performance and maintenance of the website.
