The Environment-Aware Wrapper

Here’s a handy CSS technique to make sure your content isn’t obscured by the pesky notch that seems to be present on many phones these days, and it probably already fits nicely into your existing codebase!

You can hover/tap each of the Wrapper blocks to see some guidelines showing the size of the Wrapper’s padding a bit better.

I wrote more about this on my website:

1em

1em with notch

1em with notch , adjusted

2em

2em with notch

2em with notch , adjusted

8vw (make sure you check these out at different viewport widths!)

8vw with notch

8vw with notch , adjusted

The notch shown in the code examples above and the respective sizes used are purely for demo purposes, so it probably won’t actually display nicely on a notch-obscured device!

I recommend that you use the code below if you plan to integrate it into your project, making sure to replace the default max-inline-size and gutter values with ones that make sense for you.

.wrap {
	inline-size: 100%;
	max-inline-size: var(--max-inline-size, 100%);
	padding-inline: var(--gutter, 1em);
	margin-inline: auto;

	@supports (padding: max(0px)) {
		padding-inline-start: max(
			env(safe-area-inset-left),
			var(--gutter, 1em)
		);
		padding-inline-end: max(
			env(safe-area-inset-right),
			var(--gutter, 1em)
		);
	}
}
