Customizing Footer

Hi,
You could put this code in the Custom CSS section of the WordPress customizer and it will make the last widget 100% length of the footer.

.footer-widgets-4 {
    width: 100%;
}

You could put the text inside the first widget like this:

<span style="float: left; margin: 0 20px 30px 0;">
<h6>Southside</h6>
<p>780 Lynnhaven Parkway Suite 220 <br>
Virginia Beach, VA 23452 <br>
Phone: 757-486-4529 <br>
Fax: 757-486-4530</p>
</span>
<span style="float: left; margin: 0 0 30px 0;">
<h6>Peninsula</h6>
<p>5 W Queens Way Suite 202<br>
Hampton, VA 23669 <br>
Fax: 757-486-4530</p>
</span>

So the addresses are separated by a span tag.

Also, you should change the custom CSS to this:

.footer-widgets-1, .footer-widgets-4 {
    width: 100%;
    display: inline-block;
}
