The guys on stackoverflow are just geniuses. This is one way to make beautiful text inner shadows:
.depth {
display: block;
padding: 50px;
color: black;
font: bold 7em Arial, sans-serif;
position: relative;
}
.depth:before, .depth:after {
content: attr(title);
padding: 50px;
color: rgba(255,255,255,.1);
position: absolute;
}
.depth:before { top: 1px; left: 1px }
.depth:after { top: 2px; left: 2px }
