how to make button active when clicked?

Hi, I have changed the tab container to buttons and based on the visibility the data will shown accordingly. When I clicked on the buttons I want to show that buttons like tab container with lined below that buttons for active one. I tried to apply the External CSS for that, but  when I clicked on the buttons the active buttons doesn’t stay active when I click on other place on the page. What should I do for that, please suggest.
