How to add a graphic border/frame to a gallery and/or image block?

Is it possible to add a graphic border/frame to the bottom of a gallery and/or image block?  See example screen shot of my unpublished site in the works.  I would like to add a banner border to the bottom of the image (slideshow) as circled in red.  That same slideshow repeats on all pages across the site and I would like for the banner border to appear on all the pages.  

Can you share site url? We can check easier

You can setup password & share url

I also have a second question unrelated to this one.  Should I post that separately?

Add the following to Design > Custom CSS.

.gallery-section:first-child {

  border-bottom: thick solid red;
  
  }

This is for a v7.1 site.

You can change the property values as needed.

Let us know how it goes.

Hi Creedon - That works fine and that is the exact location I would like to have a border but I would like the border to be an image instead of a solid colored line.  I'd like to use an image similar to this one attached (but this likely is not necessarily the exact one I will end up going with). 

It's a little bit tricky working with border images but it can be done.

You really need to nail down the exact image you want to use because it will probably need to be prepped with some image processing to be useable.

In general though something like the following CSS would be used.

.gallery-section:first-child .content-wrapper {

  border-bottom : 132px solid;
  
  border-image-source : url( https://images.squarespace-cdn.com/content/5f45b6f91dc07d67fcb6905c/1612479768148-XJU8BSTGWTMLNNPSZOC4/flagspng.thumb.png );
  
  border-image-repeat : repeat;
  
  border-image-slice : 0 0 132 0;
  
  }

This is for a v7.1 site.

Don't depend on the image url in the CSS being around. It's just an example I threw together.
