CSS Grad

Yigit kindly showed me how to add a CSS grad to a panel before but I can’t for the life of me work out why it’s not working. It’s the orange panel on this page http://davsar.com/halsin/home/. I’ve added the ID code ‘orange’ the colour section http://davsar.com/halsin/wp-content/uploads/2015/12/Screen-Shot-2015-12-10-at-14.31.32.png.

This is the code I’ve added to the CSS:

#orange {
background: #ff8400; /* Old browsers */
background: -moz-linear-gradient(-45deg, #ff8400 0%, #f7bf88 100%); /* FF3.6-15 */
background: -webkit-linear-gradient(-45deg, #ff8400 0%,#f7bf88 100%); /* Chrome10-25,Safari5.1-6 */
background: linear-gradient(135deg, #ff8400 0%,#f7bf88 100%); /* W3C, IE10+, FF16+, Chrome26+, Opera12+, Safari7+ */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr=’#ff8400′, endColorstr=’#f7bf88′,GradientType=1 ); /* IE6-9 fallback on horizontal gradient */
}

Can you see what I’m doing wrong?
