Post page width

Try this snippet to widen the content area:

.site-content {
    max-width: 1068px;
    width: 100%;
}

Let me know if that works for you.

Thanks!

Try something like this

.site-main {
    max-width: 1068px !important;
    width: 100% !important;
}

Make sure the !important are included

If you want to hide the date/author part then you can use this

.single .post .entry-meta {
  display: none;
}

Hi there,

Just adding that if you use Jetpack, which it appears you do, you can also hide the date and author via the Content Options section in the Customizer, without having to add any custom CSS to your site.
