- CSS only
- CSS and a Dynamic Action with one line of JQuery
- CSS and a column in the SQL query that defines the class
I'm wrapping a span around my column (AMOUNT) and use the HTML5 data- attribute to store the number in that attribute. Doing this will allow me to use a CSS selector to see if it's a negative number or not. Unlike JQuery, CSS doesn't have a :contains selector, if it did, we didn't have to create the extra data-number attribute.
