1. The CSS files in the "styles/cms" folder will be combined (in alphabetical order) and minified into a single css file cms.min.css
2. The cms.min.css file will then be duplicated and renamed to a fingerprinted file (eg. fptf1654856707_cms.min.css)
3. This fingerprinted CSS file is then used automatically on the website front-end

Any changes to CSS should be made to the files in the "styles/cms" folder either by editing the files directly or through the admin area.
Never make changes to cms.min.css or fingerprinted files as these are generated by the CMS automaticallly.
