I like to think I’m getting pretty good at working with media queries. After all, they’re arguably the most integral part of responsive web design, and I’ve been building mobile-friendly sites for years now. But when I think about it, it’s really only width-based media queries that I’m good at. I’m an absolute viking with
min-width, but yesterday I ran across a situation where I needed to control the content of my design based on the height of the device. This was a first for me. My initial thought was, I’ll just use vertical media queries… wait, do those even exist? Google soon informed me that, thankfully, yes they do. They may never be as utilized as their width-based counterparts, but they play an important role for specific types of designs.
When You Might Need Them
I’ll use yesterday’s experience as an example. My project’s design incorporates a scroll-free home page, which means everything on the page must fit within the viewport, and the user never sees a scrollbar. Once the device width gets down below 800px, the layout snaps into a traditional vertical-scrolling design. It may at first seem reasonable that the width-based media queries (i.e.
max-width: 800px) will take care of things, but what about the heights of all the displays that are wider than 800px? My design looks great on my 1920x1080 monitor, but what about smaller but relatively common sizes like 1280x800 or 1366x768?
How I Used Them
Here’s how my page looks at 1300 x 860:
Everything lays out nicely.
But now look at what happens if I shorten the viewport height down to 730px:
The bottom area begins to cut into the main area, and the three buttons are eclipsed. Not good. This is when
min-height come to the rescue.
To help everything fit nicely at this height, I chose to do three things: spread the “Innovative assessment…” text out from 66% to 100%, reduce the size of the paragraph text in the bottom area, and reduce the size of the “Learn More” links. My CSS looks something like this:
And the result is much better:
Although vertical breakpoints aren’t very common, it’s nice to know media queries are versatile enough to make them work. I definitely couldn’t have built this page without them.
