HTML box of colour is not showing up

See here: http://ift.tt/2s5DMyF

I am trying to get a box of colour sitting just above the black box at the bottom. But I cant seem to get the colour to show for some reason. Have I missed something?

.subscribebox{
        display:block;
        overflow:auto;
        background-color: #dc2b2b
        width:100%;
        height:220px;
        margin-bottom: 220px; 
        position: relative;

Cheers, Ryan
