"- The code for these logos is Extremely Tiny in size compared to the size of an image of these logos. You're saving space and bandwidth while increasing the speed of your page loading by using the css logos. Your server and customers and bank account all benefit.
- The quality is much better and crisper at any size. You can scale these up or down to nearly any size without needing to use or reupload a new image. And the size of the code pretty much stays the same.
- If you use a large version of your logo in the header and a small version in the footer you don't need to have 2 seperate images. The code for the css logo can be alterted a bit and you can have a whole bunch of different sizes of the same logo."
