Yop Poll

Hi! I want to make a reponsive poll, but I’m having some issues trying to fix the poll’s width with the sidebar.

I inserted “width” right in the code below, but despite any number I put in (I’ve already tried width 100%), it doesnt change on screen.

div#yop-poll-container-%POLL-ID% {
background:#FB6911;
box-sizing: border-box;
display: inline-block;
font-size: 14px;
color:white;
padding: 10px;
zoom: 1;
}

Can you guys help me to fix it, please!?
