How to have my posts centered

Great, it works now. Thank you!
Can you tell me how I can have a full-feature image in my posts?

Go to the customizer panel, click the Posts tab, then set the location to above content area first then I'll provide the CSS.

I set it up to the above title in the post tab.
Can you send me the CSS code?

Can you try setting it to above content area as mentioned here?

Hi Leo,

Do you mean this: https://www.screencast.com/t/03wemdpLUjp4

Your screenshot is showing that you are on the Archives tab. Make sure to click on Posts first then set the location to above content area.

I don't find it. I go to the customizer, and I don't see the post tag. https://www.screencast.com/t/BJdIVo5CKVgt

See your own screenshot here:

Do you see Posts beside Archives?

Is that it? https://www.screencast.com/t/BqMXmaVII

Hi there,

Yes, thats the correct place to change the featured image location on single posts.

Can you please send me the CSS code. Leo mentioned in the previous comment he will send it to me once I set the post

This should work now:

.page-header-image-single.grid-container {
    max-width: 100%;
}

Thanks for the code. I put it under another code and it doesn't work. The image stay the same width.
