Blue "Halo" on tabs in Safari

I have a issue on tab in safari specially. I have create tabs and when I select any tab create border blue around it.

I think it's call HALO effect.

You can check it in attached image. I tried to solved this but had no success. How do I remove that blue border when I select a tab?

Any one have a experience in this?

This is a Safari thing, where it adds a blue border around active elements. A simple way to fix it is to add the following to the styling for your tabs:

outline: none;
