<span style="color:#000066; font-weight:bold">var</span> y <span style="color:#339933">=</span> $<span style="color:#009900">(</span><span style="color:#3366cc">'#divid'</span><span style="color:#009900">)</span>.<span style="color:#660066">offset</span><span style="color:#009900">(</span><span style="color:#009900">)</span>.<span style="color:#660066">left</span><span style="color:#339933">;</span>
