overflow

I have a bootstrap 4 card in which I want to hide the overflow of the subtitle (and show "..."). How can I achieve this? If possible with pure bootstrap code... <div class="card-block p-1"> <p class="card-title">Test object</p> <p class="card-subtitle text-muted">Added by Someone with a long name</p> <p class="card-text mx-auto text-center"><span class="badge badge-pill badge-danger">€ 800</span></p> </div> Just use the text-truncate util class.. <div class="card"> <div class="card-block p-1"> <p class="card-title">Test object</p> <p class="card-subtitle text-muted text-truncate">Added by

Using -Wall -pedantic #include <limits.h> #include <stdio.h> int main(void) { enum x { a, max = INT_MAX, out_1 }; enum y { b, out_2 = INT_MAX + 1 }; printf("%d %d\n", out_1, out_2); return 0; } clang returns demo.c:9:3: warning: overflow in enumeration value out_1 ^ As you can see, compiler does not warn about out_2 overflow, his value is unknown at compile time? In the first instance, the compiler itself is trying to pick an integer that is causing an overflow, and so is warning you. It is likely producing INT_MIN . The standard allows for any value in a signed int to be an enum constant (see

单行文本溢出隐藏： overflow: hidden; 单行文本溢出隐藏显示省略号： white-space: nowrap; overflow: hidden; text-overflow: ellipsis; 多行文本溢出隐藏显示省略号： text-overflow: -o-ellipsis-lastline; overflow: hidden; text-overflow: ellipsis; display: -webkit-box; -webkit-line-clamp: 3; -webkit-box-orient: vertical; 多行文本溢出隐藏时，-webkit-line-clamp: 3; 把3改成几就显示几行。灵活多变。 原文链接： https://blog.csdn.net/vipbin520/article/details/81483955 来源： https://www.cnblogs.com/panghu123/p/11919314.html

How to calculate modulus of the form (a*b)%c? i want to calculate modulus of multiplication of two int numbers where they are almost in the stage of overflow... here c is also int (a * b) % c == ((a % c) * (b % c)) % c What about ((a % c) * (b % c)) % c ? Depending on your architecture this could be faster or slower than casting to a bigger type. You may cast a and c to long long , so the multiplication won't overflow. ((long long)a * (long long)b) % c 来源： https://stackoverflow.com/questions/5915808/how-to-calculate-modulus-of-the-form-abc

Ive just built a website for a client, and Ive got an odd problem that only occurs in Firefox browser. At the top of the page I have a navigation bar that fills the width of the browser. Ive used the technique described here http://css-tricks.com/full-browser-width-bars/ to achieve the effect as semantically as possible. Then Ive had to place overflow-x:hidden on the html and body tags to prevent the user from being able to scroll off the right side of the screen. This works great in every browser I've tested it in from Safari on Mac/PC, Opera, Chrome and heaven forbid, but even IE7, 8 & 9

h5页面在iOS上的问题解决 1、ios移动端 软键盘收起后，页面内容被顶上去，不下滑回原处 代码如下： $(function(){ $('input,textarea').on('blur',function(){ window.scroll(0,0); }); $('select').on('change',function(){ window.scroll(0,0); }); }) 原理就是弹起键盘的时候，window.scrollY会从0变到键盘的高度（例如：200），当输入框焦点失去后让scrollY回到0就好了。 但是有一个很严重的问题：如果页面上有按钮需要操作 ，例如，评论的输入框+发布按钮，输入完文字，点击“发布”，触发click事件的时候，会导致页面先触发blur事件，键盘回落，然后一切就结束了。。。。按钮点击没有起任何作用。 解决方案： 把click事件更换成ontouchstart 可以解决这个问题。 ontouchstart 事件优于click事件触发。 2、移动端 input,按钮等样式在安卓与ios上不同的解决方案 input,select,button{ 　　-webkit-appearance:none; 　　appearance:none; } 去掉 IOS默认样式即可 3、IOS上下拉动滚动条时卡顿、慢 body { -webkit

本节笔记整理 CSS笔记整理： 在标签上设置style属性： background-color: #2459a2; height: 48px; ... 编写css样式： 1. 标签的style属性 2. 写在head里面 style标签中写样式 （1）- id选择器 #i1{ background-color: #2459a2; height: 48px; } （2）- class选择器 ****** .名称{ ... } <标签 class='名称'> </标签> （3）- 标签选择器 div{ ... } 所有div设置上此样式 （4）- 层级选择器（空格） ****** .c1 .c2 div{ } （5）- 组合选择器（逗号） ****** #c1,.c2,div{ } （6）- 属性选择器 ****** 对选择到的c1标签再通过属性再进行一次筛选 .c1[n='alex']{ width:100px; height:200px; } PS: - 优先级，标签上style优先（行间样式），编写顺序，就近原则（位置上下） 2.5 css样式也可以写在单独文件中 <link rel="stylesheet" href="commons.css" /> 3、注释 /* */ 4、边框 - 宽度，样式solid/dotted，颜色 (border: 4px dotted red;)

I have a <div> on my page with a fixed height, and overflow-y: scroll; set so that the content will scroll when it passes the bottom edge of the <div> . Nothing out of the ordinary. For some bizarre reason, the mouse wheel will only scroll the content if the cursor is over empty space in the <div> or if it's over the scrollbar itself. If the cursor happens to be over any of the text content in the <div> , the mouse wheel won't do anything. This happens in both Firefox and Chrome, so it isn't just a quirk of a particular rendering engine or something. The <div> in question is overlaid on top of
