Adding Text Block to Product Page in Ishimoto Template

Site URL: http://www.chopsueybooks.com/fiction

Hi! On a product page in the Ishimoto template, I'm wondering if there's a way to insert text (and maybe an image or two) below our navigation header bar, but above our product listings. Thank you anyone for your help!

Add to Fiction Page Settings > Advanced > Header

<style>
  div#mainContent:before {
    content: "abcxyz";
    display: block;
    text-align: center;
    margin-bottom: 10px;
}
</style>

I needed the same functionality -- a code block with a custom message -- that I need to post periodically.  I tried this code snippet as well as one other one and neither displayed anything. I used the code injection for header under advanced settings.  Any idea?

Can you share site url? We can check easier

The site is still in development we have not published it yet.  Plus, I'm not comfortable posting the password in a public forum.  Any ideas?

If you can't share url here, you can hire someone.
