bootstrap align right

To aligning div in bootstrap you can use bootstrap classes like

2. float-right
3. float-none

<div class="float-left">Float left on all viewport sizes</div><br>
<div class="float-right">Float right on all viewport sizes</div><br>
<div class="float-none">Don't float on all viewport sizes</div>
