Hi, I'm inexperienced with HTML and I'm looking at someones else's code for a project at work (I know, I know - bad idea! ) Anyway, there are all of these span tags in the file like <SPAN class="624594814-13082004"> and I want to know what they do. When I did some research on class, it said that it was associated with formatting in a css file; however, none of the css files in the project have 624594814-13082004. What am I missing?
