Is there a way to create a blog with two text columns?

Every template I look at has a single column going down the middle. I would like two columns of text. I appreciate any help you can offer.

Add the following to Blog Settings > Advanced > Page Header Code Injection for the blog page. Please see per-page code injection.

<style>

  .blog-single-column .blog-single-column--wrapper {
  
    display : grid;
    gap : 30px;
    grid-template-columns : 1fr 1fr;
    
    }
    
  </style>

Let us know how it goes.

This did not give me two columns.  I added your code using "Post Blog Item Code Injection" but it does not give me two columns.

Post Blog Item Code Injection

That location is for individual blog posts and is different form where I instructed the code be installed. My code is for altering the blog post listing page from one column to two columns. Is your Layout set to Single Column?

I have the blog listing page set for side-by-side blogs, but I will change it if you tell me to.

I may not have been clear; my wish is to have each individual blog entry have two columns of text. Or better, two columns of text and then a full-width block (the width of the two above) beneath it. But I'll take what is possible.

I'm new to Squarespace, I appreciate you taking the time to help me.

Oh. My. Goodness. That worked. Thank you so much.
