You mean like this

There are three areas you need to work on.
1: Your theme. If your theme allows for three columns or whatever, then you just need to cut it up correctly and insert the right modx bits in the right places.
2: Your post Chunk. This really only calls one post but you will call it multple time in your page.
3: Your page. Here you just put your resources call. Mine looks like this:
<div class='col-3 blog' id='grid'>
[[!getPage@myPaging? &elementClass=`modSnippet` &element=`getResources` &sortby=`{"publishedon":"DESC"}` &tpl=`begridpost3` &parents=`303` &depth=`3` &limit=`20` &includeContent=`1` &includeTVs=`1` and &processTVs=`1` &showHidden=`0` &hideContainers=`1` &cache=`1` &pageNavVar=`page.nav` ]]
</div>
It will be slightly different for you and each theme but hopefully that will give you some idea.
