Customising AutoFocus to be block / question specific?

I'm just wondering if anybody has managed to use code to customise the use of the Autofocus feature? (Perhaps some Javascript to disable it on a specific question?)

If you inspect the element you can remove the autofocus by editing this line 'div class="QuestionOuter BorderColor MC QID288 animatedUnfocused"'

However, I don't have the know how to translate this into JS or CSS that I can use in the survey. Any ideas or help would be GREATLY appreciated!
