Bootstrap CSS Omit Styling

Question

I am trying to use a small snippet I found to create a slide out tab on my page. Everything seems to work functionality wise however there is a style that is being applied from bootstrap that is breaking the look of it.

This is what it should look like when the following CSS is turned off:

*, *:before, *:after {
box-sizing: border-box;
}

However, when it is applied it breaks it:

Is there any way to prevent that css from being used on that DIV?
