问题 In this page there are some links at the left sidebar that get cropped with: .widget-area .textwidget li { overflow: hidden; text-overflow: ellipsis; white-space: nowrap; } In Firefox/Chrome it's displayed properly: Unfortunately Internet Explorer 8/9/10...: The problem isn't IE 10 support for text-overflow:ellipsis.. for example this works on IE 10 too! What's wrong with my implementation? I also tried to add -ms-text-overflow:ellipsis, without any luck. 回答1: Removing the word-wrap: break

背景样式

1. 什么是背景样式 背景样式是W3C规定的浏览器如何渲染元素的背景层，用户可以在背景层添加图片，颜色等效果 2. 背景颜色3种设置方式 （1）rgb模式：分别代表红绿蓝三种颜色，取值范围rgb(0,0,0)→rgb(255,255,255) （2）rgba模式：a的取值范围0~1， 代表透明度 （3）十六进制写法：取值范围 #000000~#ffffff 3. 背景颜色写法 background-color : red ; 4. 背景图片写法 background-image : url(./images/1.jpg) ; 5. 背景平铺 background-repeat: 初始值为repeat;(默认重复) 分解为两个值: background-repeat-x:repeat; background-repeat-y:repeat; 如果不需要背景图片重复显示： 样式值可设置为no-repeat; 重复 div { width : 200px ; height : 200px ; border : 1px solid red ; background-image : url(./images/123.png) ; background-size : 100px 100px ; /* background-repeat: no-repeat; */ } 不重复 div {

CSS: How to have position:absolute div inside a position:relative div not be cropped by an overflow:hidden on a container

由 ⅰ亾dé卋堺 提交于 2019-12-17 08:09:44
问题 I have 3 levels of div : (In green below) A top level div with overflow: hidden . This is because I want some content (not shown here) inside that box to cropped if it exceeds the size of the box. (In red below) Inside this, I have div with position: relative . The only use for this is for the next level. (In blue below) Finally a div I take out of the flow with position: absolute but that I want positioned relative to the red div (not to the page). I'd like to have the blue box be taken out

Multiplication of two ints overflowing to result in a negative number

问题 Consider this snippet from the Java language specification. class Test { public static void main(String[] args) { int i = 1000000; System.out.println(i * i); long l = i; System.out.println(l * l); } } The output is -727379968 1000000000000 Why is the result -727379968 for (i*i) ? Ideally it should be 1000000000000. I know the range of Integer is from –2147483648 to 2147483647. so obviously 1000000000000 is not in the given range. Why does the result become -727379968 ? 回答1: Java (like most

Can overflow:hidden affect layout?

由 不想你离开。 提交于 2019-12-17 06:50:17
问题 There's no way for me to explain this except to refer to the following example on JS Fiddle- in it, the last BLUE box does not extend to 100% of the width as expected after I introduce an overflow:hidden attribute. I was under the impression overflow:hidden would affect visibility aspects only, and not interfere with layout. Can someone explain what is going on in this example? EDIT: This problem seems limited to webkit browsers (e.g. Chrome) 回答1: It is because overflow: hidden , among other

firefox overflow-y not working with nested flexbox

由 被刻印的时光 ゝ 提交于 2019-12-17 05:34:34
问题 I have designed a 100% width 100% height layout with css3 flexbox, which works both on IE11 (and probably on IE10 if emulation of IE11 is correct). But Firefox (35.0.1), overflow-y is not working. As you can see in this codepen : http://codepen.io/anon/pen/NPYVga firefox is not rendering overflow correctly. It shows one scrollbar html, body { height: 100%; margin: 0; padding: 0; border: 0; } .level-0-container { height: 100%; display: -webkit-box; display: -webkit-flex; display: -ms-flexbox;

OverflowError: (34, 'Result too large')

问题 I'am getting an overflow error(OverflowError: (34, 'Result too large') I want to calculate pi to 100 decimals here's my code: def pi(): pi = 0 for k in range(350): pi += (4./(8.*k+1.) - 2./(8.*k+4.) - 1./(8.*k+5.) - 1./(8.*k+6.)) / 16.**k return pi print(pi()) 回答1: Python floats are neither arbitary precision nor of unlimited size. When k = 349, 16.**k is much too large - that's almost 2^1400. Fortunately, the decimal library allows arbitrary precision and can handle the size: import decimal

一.
