Update
As @ AndrewGraham-Yooll mentioned in his answer, the fab-center attribute was removed several versions ago, so now the only way to do this is to use the container with the text-center attribute of the utility
<ion-content padding class="login-signup"> <ion-card text-center> <div class="or-label"> SOME-TEXT </div> <button outline>Signup</button> </ion-card> </ion-content>
You can center the button by adding the Ionic2 fab-center attribute as follows:
<button fab-center outline>Signup</button>
Further information on the attributes of Ionic2 can be found in the Ionic2 docs .
Regarding another div , since it is not an ionic component (like a button or label), you should focus it using the traditional css rules , as you do, or using a utility attribute like text-center .
Also note that there is no clone tag in your code: </ion-card>
