Failure F3 -images via CSS: a question

Failure F3 says it is not ok to  render images that are essential to understand content via CSS. Agreed. 
Consider: a text link with a CSS background image, say for document type PDF or  Word. 
The author uses offscreen text as part of anchor text to convey this document type and also does so via the title attribute on anchor. Is it ok then to use background image ?
Again if CSS is turned off or user-CSS is used,  the offscreen text will be available to all. This will counter the 
criticism that the purpose of the image may not be rendered when user-defined CSS  is used in place of the one used by the author. 
Is it acceptable practice to use background images in this manner then?
Will appreciate feedback.
