问题 I'm currently trying to make a text box with hiding overflowing text. It works fine, but for some part. I'm using text-overflow: ellipsis; This should put three dots ( "..." ) at the place where my text is cut off, but it doesn't place three dots, instead it places the character which looks like three dots (called 'ellipsis'). The font I'm currently using doesn't have this character, so it shows some other random character instead of three dots. Does anyone have a simple workaround (no

问题 I have a set of images that I want to display in the following pattern: [1] [4] [7] [10] [13] [2] [5] [8] [11] ... [3] [6] [9] [12] I know that I can always manually group 3 images into a div.column or something similar, but I want to achieve this layout with as simple HTML as possible. The images are 225x150. Currently, I have the following HTML: <div class='album'> <img src='img/01.jpg' /> <img src='img/01.jpg' /> ... </div> And here's my stylesheet: .album { background: #faa; display:

Box: CSS布局的基本单位　　Box 是 CSS 布局的对象和基本单位，直观点来说，就是一个页面是由很多个 Box 组成的。元素的类型和 display 属性，决定了这个 Box 的类型。不同类型的 Box，会参与不同的 Formatting Context（一个决定如何渲染文档的容器），因此Box内的元素会以不同的方式渲染。让我们看看有哪些盒子： BFC 快级格式化上下文 block-level box:display 属性为 block, list-item, table 的元素，会生成 block-level box。并且参与 block fomatting context；（块元素参与BFC） IFC 内联格式化上下文 inline-level box:display 属性为 inline, inline-block, inline-table 的元素，会生成 inline-level box。并且参与 inline formatting context；（行内元素参与IFC） run-in box: css3 中才有，这儿先不讲了。 Formatting context 是 W3C CSS2.1 规范中的一个概念。它是页面中的一块渲染区域，并且有一套渲染规则，它决定了其子元素将如何定位，以及和其他元素的关系和相互作用。最常见的 Formatting

问题 I am trying to multiply very large floats by very large integers in Python and am noticing small inaccuracies. For example: a = 45310630.0 b = 1023473145 c = int(a * b) print(c) The answer I am getting is 46374212988031352 but I know the answer should be 46374212988031350. When I change variable "a" to an integer, the multiplication is performed correctly. However, since "a" comes from a division (and might not be a whole number), I can't simply convert it to an integer. 回答1: If you use

阅读更多关于 Reducing stack load, memory allocation in C and easly casting malloc()'s return value

问题 It's known that big local/global variables may cause to a stack overflow. I know that using pointers and allocating space in memory helps to overcome this problem. But is it the only option? What happens if I have (or need) too-many pointers in global scope? Regarding the stack space: Is a global struct-type variable takes space in the stack, or acts like a pointer? Do I need to create a pointer of a struct variable type in order to reduce the stack load? Does the following code allocates

问题 I have a scrolling:auto problem with JQuery 1.4.2 and JQuery 1.7.2. I have a container DIV with 2 DIVs inside it. Like this: <div id="dragContain"> <div id="dragMe"> <div>Title goes here!</div> <div style="scrolling:auto;">Content goes here!</div> </div> </div> And I enable dragging the group by: $('#dragMe').draggable({ containment: '#dragContain', cursor: 'move', zIndex: 20000 }); And, when I do so, in FF the scrolling only works with the mouse wheel. Grabbing the scrollbar causes a drag

问题 This is what I have, I have left div, and a right div. The left div is a fixed width, and floated left.

Both of the boxes have a fixed height, and need to be scrollable (the contents inside). I add an overflow-y to the Left div successfully. However when I add overflow-y: auto to the right div, the div no longer spans the whole div. Before adding Overflow: http://jsbin.com
