Different content blocks styles based on post-type in a query loop?

@Ying, I was trying to add pagination to my archive page but was looking in the wrong place. I was checking “Appearance > Customize”, but realize its a button that is part of the Query Loop block.

All good. Thank you all for all your help! This has been a game changer.

Hey guys, sorry to come back to this so late, but curious how I would edit the code here to add a 3rd or 4th post type to the mix? I tried two different code types (below), but its not working. Any tips on what I could do to get it working?

/* Removes REGULAR post template on LINK or VIDEO posts, 
   LINK post template on REGULAR or VIDEO posts, 
   and VIDEO post template on REGULAR or LINK posts */

add_filter( 'render_block', function( $block_content, $block ) {
    if ( 
        !is_admin() && 
        ! empty( $block['attrs']['className'] ) && 
        strpos( $block['attrs']['className'], 'post-template' ) !== false 
    ) {
        $current_post_type = get_post_type();
        
        // Remove 'regular-post' template on LINK or VIDEO posts
        if ( 
            strpos( $block['attrs']['className'], 'regular-post' ) !== false && 
            $current_post_type !== 'post' 
        ) {
            return ''; // Hide block
        }

        // Remove 'custom-post' (LINK) template on REGULAR or VIDEO posts
        if ( 
            strpos( $block['attrs']['className'], 'custom-post' ) !== false && 
            $current_post_type !== 'links' 
        ) {
            return ''; // Hide block
        }

        // Remove 'video-post' template on REGULAR or LINK posts
        if ( 
            strpos( $block['attrs']['className'], 'video-post' ) !== false && 
            $current_post_type !== 'video' 
        ) {
            return ''; // Hide block
        }
    }

    return $block_content;
}, 99, 2 );

then updating the original code provided:

/* Removes REGULAR post template on LINK post, and LINK post template on REGULAR Post */

add_filter( 'render_block', function( $block_content, $block ) {
    if ( 
        !is_admin() && 
        ! empty( $block['attrs']['className'] ) && 
        strpos( $block['attrs']['className'], 'post-template' ) !== false 
    ) {
        $current_post_type = get_post_type();
        if (
            ( strpos( $block['attrs']['className'], 'regular-post' ) !== false && $current_post_type !== 'post' ) || 
            ( strpos( $block['attrs']['className'], 'custom-post' ) !== false && $current_post_type === 'post' )
        ) {
            return ''; // Return nothing if either condition is met.
        }
    }

    return $block_content;
}, 99, 2 );

Thanks @Ying. That helped a bit.
I’ll keep this as resolved and opened a new ticket as I had a few more questions about this and updating to new query block 2.0.
