The ::-webkit-meter-bar CSS pseudo-element is a WebKit extension that represents the background of a <meter> element. It is used for selecting and applying styles to the container of a meter gauge.

Syntax

css
::-webkit-meter-bar {
  /* ... */
}

Examples

HTML

html
Normal: <meter min="0" max="10" value="6">Score 6/10</meter>
<br />
Styled: &nbsp;&nbsp;<meter id="styled" min="0" max="10" value="6">
  Score 6/10
</meter>

CSS

css
.safari meter {
  /* Reset the default appearance for Safari only */
  /* .safari class is added via JavaScript */
  -webkit-appearance: none;
}

#styled::-webkit-meter-bar {
  background: lime;
  box-shadow: 0 10px 20px grey inset;
  border-radius: 10px;
}

JavaScript

js
// 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");
}
