I got Opera 10.60, I just switched from Google Chrome, and I need some help. In Chrome and FireFox there's that add-on called "Stylish". But it's not available in Opera. (If you don't know what that add-on is go here.)
I read that it's still possible without that add-on, but I didn't get it, if someone knows how to do it tell me. What I want to do is to put this instead of the regular YouTube page. Please help me.
Im sorry for all of the links, but if you don't understand then just comment and I'll explain. Thank you!

It would seem you want to add a CSS script to be loaded by webpages or a specific website. This is a common, yet very unknown, feature of web browsers. The most common usage is to block web ads using CSS scripts like "Fanboy's Adblock List for Opera"
Firstly, I am not sure the code at that site is pure CSS compliant, you may not be able to use this one or you may have to modify it. If it does work, get the code and save it to a file with "css" as the extension.
Go to the preferences
Go to the Advance section
In the list on the left, click on "Content"
at the bottom of this section click on "Manage Site Preference..."
Then click "add..." in the window that pops up.
In the new window, where there is a text box with "Site" on the left of it, type "http://www.youtube.com/"
Go to the Display section in this same window.
At the bottom is a text field with the text "My Style Sheet" above it, and a "browse.." or "choose.." button on the side, click this button.
Browse to that CSS file and select it.
Click "OK" to close and add the site to the managed site list.
Click "Close" to close the managed site window.
Click "OK" to close and set the Preferences.
Go to Youtube.

First problem, you are using Opera. Switch back to Firefox which actually supports add-ons and you will have no problems.
To answer your question though, no Opera doesn't have support for what you are trying to do. No matter if you do it with grease-monkey, stylish, etc.
Hope that helps.
