Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

::-webkit-meter-inner-element is a proprietary WebKit CSS pseudo-element for selecting and applying styles to the outer containing element of a <meter> element. Additional markup to render the meter element as read-only.

Syntax

css
::-webkit-meter-inner-element {
  /* ... */
}

Examples

This will only work in WebKit and Blink-based browsers, such as Safari, Chrome, and Chromium-based versions of Edge.

HTML

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

CSS

css
body {
  font-family: monospace;
}

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

#styled::-webkit-meter-inner-element {
  -webkit-appearance: inherit;
  box-sizing: inherit;
  border: 1px dashed #aaa;
}

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");
}
