Banner 728x90 not showing on certain pages.

Ho do I put this code side by side it's a report and opt-in form?

<right>

<script type="text/javascript">(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//forms.aweber.com/form/44/874874744.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, "script", "aweber-wjs-hgydc9lnk"));
</script></right>
<left><script data-oio-zone="type=banner&zone=1&align=left&refresh=0">
(function(w,d,e,o,u,s,t){w[o]||(w[o]={},s=d.createElement(e),s.src=u,s.async=1,
t=d.getElementsByTagName(e)[0],t.parentNode.insertBefore(s,t))})(window,document,
"script","oiopub","https://seniorincrease.com/wp-content/plugins/oiopub-direct/zones.js");
</script> </left>

You could do this:

<div class="grid-container">
    <div class="grid-50">
        Left side content
    </div>
    <div class="grid-50">
        Right side content
    </div>
</div>

Thanks for the code really helped. My question is how to put the sidebar in under the header like https://www.localsearchfordentists.com/category/blog/ if you go to any page its always under.

How do you this in generate press.

thanks,
