When creating ePubs, using non standard names in CSS can cause validation errors and stop things working properly.
For example, a forward slash (/) or a colon (:) indicates a folder in file paths and can cause problems transferring and backing up files. An ampersand (&) or a less-than sign (<) will mean different things in coding languages. A comma (,) or full stop (.) can also mean things to an operating system. Even a space cannot translate to a web URL and therefore is not truly safe to use.
In CSS, identifiers (including element names, classes, and IDs in selectors) should be taken from Uppercase letters (A-Z), lowercase letters (a-z), numerals (0-9), regular dash (-), underscore (_).
Note: If there is an export tag set up in InDesign then the export tag name is checked rather than the file name.
