Blog posts text problem

Hi there,

Remove this CSS added in the Additional CSS field in the customizer:

body.single .site.grid-container {
    max-width: 800px;
}

Then either make sure your featured image is wide enough to fill the container width which is currently at 1225px, or reduce the container width;

Let me know if this helps :)

Ok thank you. Tell me how to hide featured image from the header on this template?

Hi there,

you can use the Customizer > Layout > Blog options to disable them:
