How do I make my blog post wider?

Hello,
I want to make this page 80% width. Is there any way to fix this, as you can see, it is messing with my table.
Thanks.

(It is a page, not a post.)

Hello there,

You can use this CSS code:

    @media only screen and (min-width: 992px) {
      .page-id-701 .content-area.col-md-8 {
        width: 80%;
        float: none;
        margin-left: auto;
        margin-right: auto;
      }  
    }

That code applies specifically on the page which ID is 701. To apply for all pages, you can use this code:

    @media only screen and (min-width: 992px) {
      .page .content-area.col-md-8 {
        width: 80%;
        float: none;
        margin-left: auto;
        margin-right: auto;
      }  
    }

To implement extra custom CSS code to your site, add it to Appearance > Customize > Additional CSS from dashboard.
