Horizontally center images which overflows their container

阅读更多关于 Horizontally center images which overflows their container

问题 I am trying to center some images (horizontally) which overflows their container divs. The containers (and images, for that matter) have a height of 160px and I want to keep them with that height, even at smaller screen-sizes - but still keep the image horizontally centered. I have tried margin: 0 auto; with no luck. I came across an half-solution where it was suggested to use text-align: center; on the container div along with margin: 0 -100%; on the image itself. However this solution seems

How to block/freeze an embedded Pinterest board from scrolling down?

阅读更多关于 How to block/freeze an embedded Pinterest board from scrolling down?

问题 I have a Pinterest board embedded, which is taking the complete width at the top of the page. I want that if I scroll down, the page itself directly scrolls down; not the embedded Pinterest board. I've tried with this: #pinterest-container > span { overflow: hidden; } but the board is still scrollable. I have also tried with javascript, but somehow it is not being inserted in my html. Neither: var getThis = $('#pinterest-container > span:eq(0) > span:eq(1) > span:eq(0)'); $(getThis).css(

Overflow hidden not working in FF & IE

阅读更多关于 Overflow hidden not working in FF & IE

问题 I have overflow on the x-axis that I'm trying to hide in a container of display:table . The overflow is hidden in Chrome and Safari. As the title suggests, however, this is not happening in FF & IE 11. My fiddle: https://jsfiddle.net/z6wLnsas/1/ I have tried both overflow: hidden and overflow-x: hidden , but the issues still persists in the identified browsers. 回答1: For some reason, the overflow properties do not work on tables. Instead, try putting your table( or div with display: table ) in

用GDB Server进行远程调试

阅读更多关于用GDB Server进行远程调试

某些时候由于模拟环境的限制，调试必须要在目标板上进行。由于嵌入式系统资源比较有限，一般不能在目标板上直接构建GDB的调试环境，这时我们通常采用gdb+gdbserver的远程调试方法：gdbserver在目标板中运行，而gdb则在主机上运行。构建gdb+gdbserver调试环境的在于，要将gdb和gdbserver都编译成适用于目标板的版本。比如我们用x86的主机和 ARM 目标板，平时在主机上直接调试的时候都使用用于x86调试的gdb，但这个gdb不能用于远程调试中，需要针对 ARM 平台进行配置之后重新编译才行；而gdbserver要运行在目标板上，则需要用arm-linux-gcc编译才行。我们可以从 http://ftp.gnu.org/gnu/gdb/ 或其他站点下载GDB的源代码来进行编译。得到源代码包gdb-6.6.tar.gz之后，将target配置成arm- linux ，然后进行编译： $ tar xzvf gdb-6.6.tar.gz $ cd gdb-6.6 $ ./configure --target=arm-linux $ make $ make install 注意这时我们编译的是用于主机上的gdb程序，因此仍然用x86版本的gcc编译，而不是用arm-gcc。而接下来我们要编译的gdbserver程序则是运行在目标板上的，需要用arm

问题 I have 3 menu icons on the menu bar, but everytime it only shows 2 icons, the last one is in nowhere. my questions are: 1. there is enough space for 3 icons, why only 2 are shown? 2. if the system thinks the space is not enough for the 3rd icon, why doesn't it combine the 2nd and 3rd icon into an overflow menu? Below is my menu.xml <?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android" > <item android:id="@+id/refresh" android:icon="@drawable

Computer dosen't return -1 if I input a number equal to INTMax+1

阅读更多关于 Computer dosen't return -1 if I input a number equal to INTMax+1

问题 The type int is 4-byte long and I wrote a little procedure in C under Ubuntu to print the number I've just input. When I input 2147483648, i.e. 2^31, it prints 2147483647 rather than -1. The same thing happens when I input any number larger than 2147483647. Why doesn't it overflow to -1 as I learnt form book but seems like truncated to INT_Max and what happened in the bits level? #include <stdio.h> int main(){ int x; scanf("%d",&x); printf("%d\n",x); } I made a mistake. INT_Max+1 should equal

Centered div larger than its container overflow scroll

问题 Having an absolutely placed and perfectly centered ("translate trick") div within a container: jsfiddle. <div id='container'> <div id='content'> <p> centered... </p> </div> </div> #container{ position: relative; width: 400px; height: 400px; background-color: gray; } #content{ position: absolute; width: 100px; height: 100px; top: 50%; left: 50%; border: 1px solid red; transform: translate(-50%, -50%); } Now when this inner div becomes larger than it's container and the container has overflow:

memcpy overflow boundary exploit? (smashing the stack)

阅读更多关于 memcpy overflow boundary exploit? (smashing the stack)

问题 I'm trying to figure out if this could somehow be overflowed: void print_address(char *p) { arp_ hw; int i; hw.length = (size) *(p + _OFFSET1); //189 + 4 = 193 memcpy(hw.addr, packet + _OFFSET2, hw.length); return; } where packet is an input read from a .txt file? 回答1: hwaddr.len is an unsigned char which has range 0 to 255. So an attacker could send you a packet which declares length 255. Since hwaddr.addr is declared as a 128-byte buffer, the attacker can then deliver a payload of 127 bytes
