-**Note**: The [HTML standard suggests](https://html.spec.whatwg.org/multipage/rendering.html#hidden-elements) rendering elements with the `hidden` attribute with a CSS rule that applies the value `none` to the CSS property `display` of the element. Although the suggestion is not normative, known user agents render it according to the suggestion (unless the content specifies another CSS rule that sets the value of the `display` property). If a user agent does not follow the suggestion, this definition may produce incorrect results for this user agent.
+**Note**: The [HTML standard suggests](https://html.spec.whatwg.org/multipage/rendering.html#hidden-elements) setting the CSS `display` property to `none` for elements with the `hidden` attribute. While not required by HTML, all modern browsers follow this suggestion. Because of this the `hidden` attribute is not used in this definition. In browsers that use this suggestion, overriding the CSS `display` property can reveal elements with the `hidden` attribute.
