Let’s start with the errors.
1. You have two style references in the HEAD of your header.php
that instruct the browser to put two graphics in your header. Clean those up and make sure that they are either the same or different but “together”.
2. The following is in the wrong place. Move it closer to the rest of the style references. It is outside of the HEAD and it must be within it.
<link rel="stylesheet" href="https://www.nascarusa.net/wp-content/themes/scattered2/nicetitle.css">
And add a self closing tag at the end so it looks like tered2/nicetitle.css">
3. <title>Leander Fire & Rescue</title>
can not feature an ampersand and must have the word “and” or the character code which is &.
4. XHMTL requires that tags that are not closed be self-closing. In short, every <br> need to become
.
5. Your sidebar links are totally messed up. For instance:
<ul>
<h2>Post Date :</h2>
<li>Monday, May 23rd, 2005 at 12:36 pm</li>
needs to be corrected to be:
<h2>Post Date :</h2>
<ul>
<li>Monday, May 23rd, 2005 at 12:36 pm</li>

That should get your started and clean up a lot of the mess.
Skip the fauxcolumns as that is like using a hammer to slice a diamond.
