Creating columns in WordPress

You may use

<ul>
<li>

styles to maintain the list.

Wouldn’t this just create a list? I need three columns. Could you perhaps give an example of code for three columns that will work in wordpress?

Check the footer

Isn’t that an html page? Not wordpress?

I copied and pasted the code from the footer of your page into my WP page, but I just get a straight list. Please see https://www.wethepeoplealaska.org at the bottom.

You need to create the style via stylesheet.
