Align Element (float)

Hi,

Can't find the solution in the docs.

Text-right,
Pull-right,
float-right

Don't work anymore in the 8 version. Or maybe something change and can't find it.

for example

<div class="row">
<div class="col-lg-6>
<div class="pull-right>
some text I want to the right of the col
</div>
</div>

If someone can help ...
