thats actually super easy if i didn't misunderstand you

    .col-style {
        columns: 250px;
        height: 100vh;
    }
    <div classes="col-style"><p> everything in here will be in columns of 250px width and the scroll bar will be going to the right instead of the bottom</p></div>

try it out on the linked articles <body> element :) (you'll also have to remove the margins on that page however, as they're using negative values)
