I am a first time JavaScript student and I have a school question, we need to indicate the data types that width and style.width accept.我是第一次 JavaScript 学生，我有一个学校问题，我们需要指出 width 和 style.width 接受的数据类型。

I know data types are number, string, null, undefined, boolean and object.我知道数据类型是数字、字符串、空值、未定义、布尔值和对象。 We haven't learned to code yet so I don't know how to test my answers nor can I find it on the web.我们还没有学会编码，所以我不知道如何测试我的答案，也无法在网上找到它。

The properties on the style object is based on the CSS spec, specified as a String value eg element.style.width = '10px' .样式对象的属性基于 CSS 规范，指定为字符串值，例如element.style.width = '10px' 。 As for width, please read more here .至于宽度，请在此处阅读更多内容。 More specifically what is eligible to be used, please see width<length> and width<percentage>更具体地说，什么是有资格使用的，请参阅width<length>和width<percentage>
If you try to set an invalid value, it will be invalidated and not applied on the element.如果您尝试设置无效值，它将无效并且不会应用于元素。
