which is the style to apply on a div to make component (button) centered in the botton without knowing the size of the remaining space that will take the div and the size of the button because this style will be generic.

I used this style but it didn't work for me: 

```
<div location="buttonLayout" style="display:flex; justify-content:center; align-items:flex-end ;"></div>

```

The button is centered but not placed in the bottom of the remainig space of the parent div.
