I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">versus</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for against that I've seen before include "Facing" , "Opposed" , "Anti, touching" , "Versus - in contact with" , "Not supporting" .)
