JavaScript

// Safari requires <meter> elements to have an `appearance` of `none` for custom styling
// using `::-webkit-meter-*` selectors, but `appearance: none` breaks rendering on Chrome.
// Therefore, we must check if the browser is Safari-based.
const is_safari =
navigator.userAgent.includes("AppleWebKit/") &&
!navigator.userAgent.includes("Chrome/");
if (is_safari) {
document.body.classList.add("safari");
}
