Change Blog Layout Width - Marketer Theme

Also, could the blog layout be not boxed?

Hi there,

you can use a Layout Element to make the container smaller:

And you can change the Customizer > Layout > Container --> Content Layout to One Container

Thank you, David.

I have applied the changes. How can I remove the boundaries around the single blog post and on the blog layout page?

Is there a way to add margin from the top on the single blog post?

You have this CSS on your site:

.inside-article, .sidebar .widget, .comments-area {
    border: 1px solid #e8eaed;
    box-shadow: 0 0 10px rgba(232,234,237,.5);
}

Delete this CSS to remove the border. I cannot see where the CSS is coming from because of you have a cache enabled, but its most likely in Customizer > Additional CSS

For the additional space above the post, you can increase the Top Padding in Customizer > Layout > Container. If you want it to only apply to the single post then use this CSS:

.single #page .inside-article {
  padding-top: 40px;
}

Thank you so much David for your help.
Everything looks great now.

Glad to be of help
