验证 CSS 高度/宽度的规则？
我正在创建一个输出
这些是我以前见过的高度和宽度设置类型。这些都有效吗？我在哪里可以找到所有接受的格式？是否有任何值被认为无效，但被用作跨浏览器兼容性的技巧？
- 1px
- 10%
- 99.99%
- 100
我可能只是让用户在这些字段中输入他们想要的任何内容，但现在我很好奇。
I'm creating an ASP.NET control that outputs <object> and <embed> tags. I want the control to have "Height" and "Width" properties, since both of those tags require them. I was also thinking of validating the height and width at runtime. I'm wondering exactly what the valid ranges are so I can be sure I have valid sizes.
These are the types of height and width settings I've seen before. Are these all valid? Where could I find all the accepted formats? Are there any values that are considered invalid, but are used as tricks for cross-browser compatibility?
- 1px
- 10%
- 99.99%
- 100
I may just go the route of letting the user input whatever they want in these fields, but now I'm curious.

请参阅 属性值下的
heightW3C 页面。为了回答您的具体问题，所有这些值都是允许的。省略px没有任何效果。See the W3C page for
heightunder Property Values. To answer your specific question, all of those values are permitted. Omitting thepxhas no effect.
