There are many design elements that go into creating a nice website and even after a designer has gotten the hang of all the technical lingo that might be required in the creation of a website it's likely that it will still be necessary to check that website's appearance in other browsers apart from the one in which it was created. It's very possible to create a website that will look good in all browsers but it's still a good idea to open other versions just to make sure all of the coding is correct and looks as it should.
