2. Introduce the absolute path of the local computer, such as the image named "a.jpg" in the images folder under D disk:

Absolute path must enter a complete description of the path, this method points to the link destination address is clear, but there is a disadvantage is that once the file is moved or deleted for a long time will cause the file can not be displayed, you need to reset the relevant links.

What is a relative path?

Relative path refers to the relationship between the path of the file and the path of other files (or folders).

"../" is often used in relative paths "to indicate a superior directory, if there are multiple superior directories, you can use multiple"../ "means superior;

If you link to the current directory, just enter the name of the linked object, such as: a.jpg;

If you link to the next directory, simply enter the directory name, or./ File name, and then enter the object name, such as: images/aaa.jpg or./ images/aaa.jpg;

To sum up, if you quote the style.css file in the css folder under the parent directory, the code is: ../../ css/style.css 。

Relative path is suitable for internal reference of website, as long as it is in the same site, you can freely construct links between files, independent of the server where the site is located, this writing form omits the same part of the absolute path, and can change the server address of the site file.

The root directory refers to the topmost directory of the logical drive, and the local root directory such as C disk, D disk, etc.;

Web site root refers to the use of multiple sites on a server at the same time, or a large-scale site needs to be placed on several servers.

The root directory is represented by "/". For example, the file named "a.jpg" in the images folder under D disk is coded as: /images/a. jpg.
