I’d like to achieve this result

there are many tutorial around like this but they work with a fixed text and columns. I print a variable-length text inside my two column layout in this way
#cols {
column-count: 2;
column-gap: 20px;
}
<div id="box">
<p id="cols">
Lorem Ipsum....
</p>
</div>
so I can’t use a technique like that, how can I put an image in the middle in this scenario?
