效果上没有什么不同，但是只要是写在 CSS 里面的都只是纯展现，可以不遵循任何道理（比如 display，狗都可以伪装成猴的样子），而 HTML 则可能带有语义。
hidden 表示该元素是不相关的、不需要的，这个含义是主要内容，“隐藏”的效果只是附带。也许看上去跟 display: none 没有任何区别，但是在我们不知道的地方，比如屏幕阅读器或其他一切依赖语义的地方，可能就有它的价值体现。
更多信息可参考：hidden - HTML (HyperText Markup Language) 不管什么情况，你知道一个原则就 OK 了：
HTML 是内容展示带有语义，CSS 是界面样式相关。
那么 hidden 这个属性，就表示与浏览者不相关、不重要，浏览器在解析的时候，既然不相关就直接隐藏掉了。如果你有些东西与用户不相关，比如 提交信息的 input 等，就可以用 hidden。
display none 就是从界面、视觉上的隐藏。如果你需要临时隐藏一些东西后面会再切换出来，比如 下拉菜单 等，就可以用 display none。因为它不是跟用户不相关，只是目前还不能展示出来。 没区别，几乎一模一样。
html5这么多知识点需要学习和掌握，建议不要在这样无关紧要的地方抠细节，没有太大意义。
