How can i show my old posts on top and can i wrap posts?

So now new posts show on top and want the old ones on top.

You’ll need to add a custom query to the relevant template files in your theme.

Can i wrap the posts so you only see the title and date en when you click it it opens the post?

Yes – again by editing the relevant template files in your theme.

Argg this stuff is hard, this is the only thing that i need to finish the site.

What files are you talking about, which 1 need to be edited and can you pls help me with coding.

What files are you talking about

That depends upon what pages you want to change, how your site’s front page is configured and what template files are present in your theme.
