Note:
Author mode, the author of the web document's style, is choosen by default. When you choose user mode, your own browser preferences (settings) take preference over the author's styling. There are a lot of additional options for disabled people etc.

Can this be the reason that you complain about how pages are presented in Opera? You have simply not understood the different and important settings (options) in the browser.
