This is a great way to create a shadow on your text by using CSS instead of images.
text-shadow: 10px 20px 30px #000;
The first value (10px) is the horizontal offset. A positive number will offset the shadow to the right, a negative to the left.
The second value (20px) is the vertical offset. A positive number will offset the text shadow to the bottom, a negative to the top.
The third value (30px) is the length of the actual shadow.
The final value (#000) is the color of the shadow.
