I wonder if that&#x27;s the case (what was meant). When I first worked with ASP.NET 1.1, getting it to work (feature-level) with Opera often required forgoing most of the &quot;managed&quot; control properties and using CSS&#x2F;JS directly. The backend .NET code was much more of a joy to work with than Classic ASP, but the managed ASP.NET frontend portion, not as much.
