CSS for Opera Mini only

I have some issues with css and Opera Mobile.

Without effecting other pages is there a way I can fix the css on opera mobile?

Here are my issues:

1. Links aren't underlined

2. CSS below does not center like button

   #likeButtonWrapper  //Center like button
       {
       ma开发者_C百科rgin: 1em auto;
       margin-top: 2em;
   }
   

For the button issue, margin: 1em auto; only works to center an item when it knows the width of the item. Set a width and see if that fixes it.

My understanding is that Opera Mini disables link underlining automatically. See http://my.opera.com/community/forums/topic.dml?id=821082

Not sure if you can override it with a more specific style such as

a.link{text-decoration:underline;} 

or

a{text-decoration:underline !important;}
