Based on the Codeschool lesson (2.6 Tabs Inside Out ), I made an example of tabs, but I don’t understand where the numbers on the tabs come from? How to remove them?

Answer 1

<section ng-init="tab = 1">
    <ul class="nav nav-pills">
        <li ng-click="tab = 1" ng-class="{active:tab === 1}"><a href="#">Descr</a></li>
        <li ng-click="tab = 2" ng-class="{active:tab === 2}"><a href="#">Specs</a></li>
        <li ng-click="tab = 3" ng-class="{active:tab === 3}"><a href="#">Reviews</a></li>
    </ul>
    {{tab}} <!-- Вот здесь Вы сами и выводите номер таба -->
</section>
