问题 In C, unsigned int size = 1024*1024*1024*2; which results a warning "integer overflow in expression..." While unsigned int size = 2147483648; results no warning? Is the right value of the first expression is default as int? Where does it mention in C99 spec? 回答1: When using a decimal constant without any suffixes the type of the decimal constant is the first that can be represented, in order (the current C standard, 6.4.4 Constants p5): int long int long long int The type of the first

text-overflow ellipsis 自动截断超出范围的文本

今天前端同事问了一个小技巧的问题，怎么控制超出范围的文本自动截断，给她写完后来普渡下众生`(*∩_∩*)′ 1、普通的文本段 对于普通的文本段的话只需要定义下面三个属性 p { white-space: nowrap; /* 使内容不自动换行 对应的还有 normal 自动换行 */ overflow: hidden; /* 超出容器范围的内容隐藏 */ text-overflow: ellipsis; /* 文本超出容器范围以 ... 做截断 */ } <p>hello world hello world hello world hello world hello world hello world hello world hello world hello world hello world </p> 2、表格的文本段 当在表格中想要实现此效果时需要将此表格的 table-layout 设为 fixed table { width: 100%; table-layout: fixed; /* 一定要有此属性 */ } td { white-space: normal; overflow: hidden; text-overflow: ellipsis; } 其他与普通文本段的定义没区别 来源： oschina 链接： https://my.oschina.net/u

Move Child's Overflow To Next Row If Current Row's Width Too Narrow

问题 EDIT: I'm building a simple event calendar(using HTML+CSS) and am currently working on multiple day events. I'm a beginner to HTML&CSS and have a pretty straightforward question, but i just can't seem to find the answer: How can you make a child div overflow to the next row(of divs, etc.) if there isn't enough space on the screen(or on the row of divs) to fit the whole child div? And could you do it with only HTML&CSS(if possible) at most a bit of JavaScript? Here's what i mean should happen:

Set overflow-y visible while overflow-x is auto so that content can vertically overflow parent's container

问题 I'm using position: absolute and position: relative to display text over an image if its parent is hovered over. The container that the text and images parent div is in is set to overflow-x: auto , causing it to have a horizontal scrollbar. I want the text that appears to vertically overflow the #container element (and the horizontal scrollbar), but this is not happening - instead, a vertical scrollbar is appearing in the container. I do not want the containers height to expand to the height
