You need to use a CssSelector in the format ".nameA.nameB.nameC" you can have as many as you'd like, just add the "."

Alternatively you can match the whole attribute (you can also do this with xpath): "[class='exact class name here']" XPath - "//[@class='exact class name here']"

There are ways to do starts with or ends with or contains too (in both CSS and xpath) which helps if the classes are generated dynamically.
