Difference between ion-tabs and class="tabs"

anyone please tell me the difference between ion-tabs and class=“tabs”

ion-tabs is the directive as documented here: http://ionicframework.com/docs/api/directive/ionTabs/ . It leverages some extra perks. Class tabs is mainly used for styling or if you’re repeating over your own controller defined class items (for example)

Thanks for that. But I just curious about what is that extra functionality … For ion-list directive, we can take action like delete, more etc which s not available upfront when we use the class list. Sameway, i would like to know more about that additional feature with ion-list.
