If you are referring to "yadda, yadda" as the CSS mistake, then it's not a mistake. It is a
Seinfeld reference meaning 'I don't need to go into all the details here because you get what I'm trying to say'
If that is NOT what you are talking about, please elucidate.
...and yes, I know.... quoting Seinfeld is probably showing my age a little too much
