I recently posted the IE logo in CSS, and then by accident I receive a link with the Opera logo as well.
There are three different renderizations that we can use:
- The first one ever is brought by David Desandro, and the best thing about it is that he posted the code so anyone can use it and do test by themselves.
- Håkon Wium Lie, published in My Opera Blog a logo created and named standard compliant Opera logo with a different code. This code seems to be more effective because you can actually see differences in several browsers.
- Another one is one by Jan Henrik Helmers. This seems to be quite hard because the results are quite surprising.
