Above the Fold, Breaking the Rules

On the web there is no fold.

Stacked newspapers
Newspapers have a fold. The web does not.

It's been hammered over and over that, on the web, there is no fold.

And rightly so.

The web isn't print. The web is a fluid medium. A medium of unpredictable environments and viewports.

With all this variability, there isn't one height that can be considered the fold, so the mantra is that there is no fold.


In college, I took an art course in which we discussed the work of the famous Dutch abstract artist Piet Mondrian.

Composition with Red, Blue, and Yellow
Piet Mondrian's 'Composition with Red, Blue and Yellow', 1930

What stuck with me all these years later is what the professor said about rules. Mondrian was a brilliant, gifted painter who, in his early works, demonstrated that he knew the rules of painting. When he moved into abstract work he chose to break the rules that he already knew.

The point was this: you have to understand and respect the medium before you can break the rules.


There is no fold on the web. Recognizing that that's the rule, and recognizing that scrolling will always be the default interaction, let's break the rule.

Let's create a fold.

With all of the variability in screen sizes, how do we create a consistent fold? How do we create an element that is always exactly as tall as the viewport—no taller, no shorter?

Enter the humble vh. This unit of length lets us specify a height relative to the viewport size—perfect! So if we create an element that is height: 100vh, it will be exactly as tall as the viewport; that is, it will be above the fold. Everything after it will be below the fold.

.abovethefold {
  height: 100vh;
}

This has a small problem. Respecting the medium, we know that people will scroll if they think there is more content. But how do visitors know they can scroll when all they can see is our above-the-fold element? How do they know there is more content?

We need an affordance that communicates to visitors that yes, there is more content, that yes, they can scroll.

So what if the content just barely starts to show at the bottom of the screen? What if there's one, maybe two lines of text that visitors can see? Then they know there's more; then they know they can scroll.

.abovethefold {
  height: calc(100vh - 1em);
}

So instead of height: 100vh; we can use height: calc(100vh - 1em); to bring the first bit of content just barely into view.

I was playing with the fold on my homepage, and I'm happy with the results: a very minimal above-the-fold experience that fits the feel of the site, but with the affordance that there's more content if you're willing to scroll.


Usually on the web, there is no fold. But sometimes you have to break the rules.
