#iefix and # characters are not recognizable in reactive web theme

I am encountering error on my previously working style sheet, reactive web is not recognizing the #iefix and # characters on the style sheet. Can someone help me with this? Thanks!


Do you mean you're using selectors that start with a number sign ("#")? 

This isn't recommended as OutSystems HTML element IDs will be generated, and there's no way to predict the final ID value. You'd usually replace these with a class selector (".") - is this something you could attempt?
