Modern Device Dimensions for Chrome DevTools

These are modern “Emulated Devices” (a.k.a. responsive dimensions) for Chrome DevTools’ Mobile Device Viewport Mode.

They are specifically Apple devices, subtracting for recent Safari UI (as in window.innerWidth/Height), and cleverly sorted with some dark-arts unicode shenanigans. (This glitchy, unloved portion of the tools sorts lexicographically, because of course it would.) Ergonomics!

Note

Updated June 2025 with some notes from folks below! TL;DR: use Vibranium!

Setting the current date and time on a HTML5 date or datetime field with Javascript

By default date.toISOString returns UTC time instead of local time. So you'll need to calculate the timezone offset first.

//Get the local date in ISO format
var date = new Date();
date.setMinutes(date.getMinutes() - date.getTimezoneOffset());
var datestr = date.toISOString().substring(0, 10);
