My advice is to avoid using any credit cards at all costs. Have one very small card (like $500 or less) for an emergency. Or to build your credit like buy something really cheap, then pay it off 100% when you get the bill. That builds good credit.

Credit is like a snake in the grass but it not only bites you but your family. My dad sold my mom's house so he could pay off all his credit cards before he dies. $180,000 in stupid credit for stupid things. He did it because he knew that if he died, they would then come after me for the payment!
