I'll believe Tyssen any day over some random web site.

These form objects are imported from the underlying operating systems which is why they look different in each type of system.

In Windows all you have to do is change your theme and watch the form element styles on all your forms change in your web browser. From any site.

Some browsers will accept some CSS rules, but it's different for each browser and you are better off leaving them alone and accepting the differences. The web is not paper!

Well, as the author of that article says near the beginning:

but he/she has found a workaround to produce an effect that looks like the border's been removed. The problem with that method is that if the text size is larger than what the designer originally envisioned, then parts of the select will be unreadable, due to the use of overflow:hidden.
