I want the 'td' to be of fixed size and if the content becomes larger than the 'td' size, I want a scroll bar to appear only on that particular cell. Is there a way to achieve this? 回答1: Yes you can do that. The easiest way is to put inside your cell a div filling it and set its overflow style property. CSS : div.scrollable { width: 100%; height: 100%; margin: 0; padding: 0; overflow: auto; } HTML : <td><div class=scrollable> Some content with a

I have an issue when running with iOS7, in which all the views are tucked under the status bar. I fully understand this is a new feature with iOS7, in which this can be expected. However, all of the solutions for fixing it to not do this are not working. I have an image at the top of the view that always shows under the status-bar, and I'm not using nav-bars or anything like that. I have tried

If both paths include a root element, the capability to construct a relative path is system dependent. With "system dipendent" do they mean only that if an element contains a root it will work only in the platform specific syntax that has been written? I guess it is the only thing they mean.
