You can make a circle around your Ordered List, <ol> as below without using image formats like JPG or PNG, so this way you can reduce the developing and loading time for your site.

DEMO: How It Looks

CSS

    padding: 8px;
    display: block;
    -webkit-border-radius: 50%;
    -moz-border-radius: 50%;
    border-radius: 50%;
    width: 65px;
    background: #fe862c;
    color: #fff;
