overflow

问题 I found this solution Inset box-shadow beneath content which works just fine, but when the outer container div has to be scrolling (overflow), the inner div which has the box-shadow will scroll with the content. How to fix this? div { height:300px; color:red; position:relative; } div div { box-shadow:inset 0 0 10px black; position:absolute; top:0; left:0; width:100%; height:100%; } <div> <div></div> a </div> 回答1: you can consider adding an overlay and use z-index to specify which block is on

问题 I've elements with overflow:'scroll' style setting. All mobile devices but windows phone enables scrolling by touch-drag. Is there any solution to make this work ? 回答1: Solved.

问题 From Mozilla's description of the "overflow" property: Setting one axis to visible (the default) while setting the other to a different value results in visible behaving as auto. I can't see any benefit of doing this, or any kind of problem that is circumvented with this. Why is this part of the specification? 回答1: Consider this example where we have overflow in both direction: .box { border:1px solid; width:200px; height:200px; } .box:before { content:""; display:block; height:150%; width

问题 I have a local page in android webview, pages's html and body both has width:100%;height:100%;overflow:hidden; , and the #result-popup-wrap has the following css: #result-popup-wrap { position: absolute; left: 0; bottom: 0; width: 100%; height: 245px; background: #fbfbfb; border-top: 1px solid #dcd9d5; -webkit-transform: translateY(100%); } but, as you see, when I scroll to bottom of the page, I can see the #result-popup-wrap , which should not be visible. Any help is appreciated! 回答1: Just

问题 Can someone explain to me why overflow has the following effect. In the jsfiddle below I have a Div floated to the left with a width and height set. Next I have a Content div. You could think about this as a left navigation and a content of a site layout. Inside the content I have two Divs which are identical apart from one has overflow:auto the other doesn't. The one with overflow:auto currently respects the floated div and shortens its width to not clash with it. Were as the other one

问题 How would you fix this code? template <typename T> void closed_range(T begin, T end) { for (T i = begin; i <= end; ++i) { // do something } } T is constrained to be an integer type, can be the wider of such types and can be signed or unsigned begin can be numeric_limits<T>::min() end can be numeric_limits<T>::max() (in which case ++i will overflow in the above code) I've several ways, but none I really like. 回答1: Maybe, template <typename T> void closed_range(T begin, const T end) if (begin <

问题 This is a rather theoretical question, so while the language is specifically Java, any general solution will suffice. Suppose I wanted to write a trivial factorial function: long factorial(int n) { //handle special cases like negatives, etc. long p = 1; for(int i = 1; i <= n; i++) { p = p * n; } return p; } But now, I also want to check if the factorial overflows (without simply hard coding a MAX_FACTORIAL_PARAMETER or something of the like). In general checking for overflow during

问题 This is my code http://jsfiddle.net/FbC86/. If you open this page with Chrome or Firefox the text inside the cell is overflowing correctly through a vertical scrollbar. If you open it with Internet explorer it doesn't work properly. I need your advice as i am new to web development and i cannot find any solution to this problem. Thanks in advance! Part of the code: CSS div.main { width:100%; height:100%; display:block; position:relative; overflow:auto; } div.transparent{ padding:3em;

问题 My android app supports 2.2 and higher. I'm using the appcompat support library for the action bar, so it should only show if there are things that don't fit. I want my action bar to support the overflow button (the three vertical squares) that reveals a menu with the other items when clicked. In my menu file, I have three items set up. However on the app I only see two of them, and the overflow button is not showing as well. activity_menu.xml <menu xmlns:android="http://schemas.android.com

问题 I have the following function to get an int from a high-byte and a low-byte: public static int FromBytes(byte high, byte low) { return high * (byte.MaxValue + 1) + low; } When I analyze the assembly with FxCop, I get the following critical warning: CA2233: OperationsShouldNotOverflow Arithmetic operations should not be done without first validating the operands to prevent overflow. I can't see how this could possibly overflow, so I am just assuming FxCop is being overzealous. Am I missing
