I find scrolling all the way to the bottom of a thin column to get old fast, however, especially when the article is longer than can fit into a single page.

It's pretty easy to constrain the height of the article text div element to be slightly less than screen height (using `height: 100vh`, or maybe slightly smaller if you have a header), which makes the columns fit vertically within the screen but causes more columns to appear off-screen to the right. However, you can override PageUp and PageDown to scroll left and right instead: https://github.com/publicdomaincompany/scroll/issues/10#issu....

That's pretty satisfying if you like to read in thin columns - almost like a poor man's PDF but completely in HTML.

    .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>

In Emacs, it is possible by using "follow-mode":

Open a "large" file.

M-x follow-mode

C-x 3 ;; to split vertically

And adjust splits width as many times needed.

I usually use 3 splits with "visual-line-mode" enabled.
