Change background in footer widget

I have changed the background color code from #5b9312 (=green) to #193549 (=Royal blue) but no matter how much I clear caches in any browser or in the wp itself it does not change from green to blue.

Below is the code I use. Any hints on what might be wrong?

#footer-sidebar3 {
float: left;
border: 1px solid #fff;
border-radius: 20px;
width: 100%;
margin-left:5px;
margin-right: 5px;
background-color: #193549;
color: #ffffff
}
