Works the best. If you want to use it sitewide, without having to add this syntax to every class or ID, add the following CSS to your css body:
body {
-webkit-font-smoothing: antialiased;
text-shadow: 1px 1px 1px rgba(0,0,0,0.004);
background: url('./images/background.png');
text-align: left;
margin: auto;
}
