Relative and absolute paths to files and root relative paths

One, Absolute path

Provides the complete hostname, path information, and full document name of the target document.

Second, relative path

The path starting from the current document.

If the current document and the target document position are parallel, the document's full name is written directly;

If the current document and the destination document are located in parallel to the folder location, it is written as: folder name / target document full names;

If the current document is in the same folder as the target document location, write as .. / Target document full name (.. / indicates an up-level folder).

Third, Root relative path

The path starting from the site root directory.
