How to make the featured image the full image

Done.

So that gives you the layout you are after right?

Featured image
Then title
Then post meta

No. I want the post meta and the category to show like it does on the Info starter site.

The only thing I want different is a full featured image with no text overlap.

Ok so follow the steps here:

1. Edit the Post page hero which is set to Draft currently.

2. Select the Container that holds the post title and meta, then Copy it:

3. Create a new block element and paste the container block copied in #2.

4. Set the new block element to be Post Meta Template:

There might be some additional tweaks needed but let's start with this.

This mostly worked but I've got a duplicate title and author name showing as indicated in the screenshot below in the private field.

Not quite sure how to fix that.

I figured it out. Thank you so much for your help on this Leo!

No problem :)
