3. Configuration file
Configuration files help designers manage template global variables in files. The simplest example is the template color variable. Generally, if you want to change the appearance color of a program, you must change the color variable of each file. If there is this configuration file, the color variables can be saved in one place, and you can update your colors by simply changing this configuration file.
