Align button inside Alert

Question

The needing leaves a button lining inside the boostrap "Alert" element. I tried to do this with the "pull-right" class, but half the button is outside the element.

Someone can help me?

Dude use Bootstrap’s Grid, use row>col etc, in case you need to use offset in col to generate "empty spaces" between a column and another. In this case I even removed the class pull-right that you’re actually putting float:right in his btn. I suggest you stop by for an hour to read the Grid documentation! https://getbootstrap.com/docs/3.4/css/#grid

Follow the image code above. This option does not use extra CSS, only the grid and BS classes. If you want to customize CSS you can also...

Place the button inside a div with the class .text-right. This class applies the property text-align: right. For being inline, the button will be right aligned:
