Is separation of Content, presentation and behavior possible every time ?
是否每次都可能分离内容、表示和行为?
Many time through javascript we add classes to html and we use in CSS visibility:hidden inline.
很多时候，我们通过javascript向html添加类，并在CSS中使用:隐藏内联。
Should we always invest time to keep all separate?

While it is usually possible, it is often not practical. As you say yourself, it costs time. Whether you are willing to invest that time is subject to many factors, of which purism is only one.
虽然它通常是可能的，但它往往不实用。正如你自己所说，这需要时间。你是否愿意投入时间取决于很多因素，而纯粹主义只是其中之一。
In fact, it can be argued (and I've witnessed it being argued first-hand) that since tags such as div or span don't carry any semantical meaning in and on themselves, but have been invented specifically for styling, the moment you use a single one of them on your page, you are already mixing content and presentation. This is a nice philosophical discussion to have, but in business context it leads nowhere.
事实上,它可以认为(我亲眼看到了它被认为),由于标签如div或跨度不携带任何语义意义和在自己身上,但已经发明了专门为样式,当你使用一个其中一个页面上,你已经混合内容和表示。这是一个很好的哲学讨论，但是在商业环境中它却没有任何结果。
So, while you should always try to separate content, presentation and behavior as much as possible, you will always have to stop somewhere, if only to get other things done.
所以，尽管你应该尽可能地把内容、表现和行为分开，但你总要在某个地方停下来，如果只是为了完成其他事情的话。
