How to add Background Image that lays under the header for a blog post?

Site URL: https://www.kaci.io/growth-stories/ojtpx8stfab3p7xlc1bkft907usraq

Hi! Across my whole website I have background images that bleed up under the transparent header. My logo on top is white. 
I'd like to be able to do the same for an individual blog post. Is there any way to do this?

I obviously can't just leave the page white because then my logo doesn't show up. But I don't like the other full colour options. 

Help?

Add this code to Blog Page Settings > Advanced > Header

<script src="https://code.jquery.com/jquery-3.4.1.js"></script>
<script src="https://assets.codepen.io/3198845/WMBlogPostBannerFREEv2-3.js"></script>
<div 
     data-wm-plugin="blog-post">
</div>

@tuanphanThank you, that worked to get the image in, but is there any way to edit it? 

When I've viewing my website live, the words are all scrambled on top of the image. But when I go into editing mode, the header image disappears and the words go back to normal. See images attached.

Do you still need help on this?

Hi @tuanphan, I used this code and it worked perfectly - is there anyway I can edit the font position (centred and middle) / font family of the text overlay?

I would like it to match the rest of the pages without changing the title font family on the blog overview page.

Add this to Blog Page Header

<style>
  section.has-background.wm-blog-banner.blog-item-wrapper {
    display: flex;
    align-items: center;
}
  .blog-item-top-wrapper * {
    font-family: monospace !important;
}
</style>

@tuanphanThank you so much! This worked perfectly.
