Minify CSS and JS

1. Optimize CSS and JS separately

You can also run the files separately minify_css.bat (minify_css.sh) or minify_js.bat (minify_js.sh) You can use some of them.

For Windows:

minify_css.bat 
minify_css.bat D:\development\web\zeppelin\styles

For Linux or MacOS:

./minify_css.sh
./minify_css.sh ../../css

Note: When the folder is not specified, the default css and js folders will be used.

2. Only minify default CSS and JS files.

Also you can generate .min files only of main.css and scripts.js

minify_main_css.bat
minify_scripts_js.bat
