Clip child to parent element with border-radius

放肆的年华 提交于 2019-12-08 03:22:11
问题 How do I force clip a child to a parent element that has rounded corners. <div class="item" > <div class="top"> <h1>Tile</h1> <h2>Click me</h2> </div> <div class="behind"> <h3>Details</h3> </div> </div> When animating the child, its ignores the border-radius of the parent element. Is there a way to fix the two corners on the top? .item{ text-align: center; cursor: pointer; overflow: hidden; height: 280px; width: 280px; float: left; border-radius: 5px; background: white; margin: 10px; position

Get true content size

心不动则不痛 提交于 2019-12-08 02:54:17
问题 I am wondering if its possible to get the size of the content ( not the div ) in javascript/jQuery. So if the box has a height of 200px but there is only one line of text, the content size would be around 12px. Thanks for all your help 回答1: You may create a range of the element's text-contents and use the properties of the range: /** * @param object o DOMElement * @return int|null boundingHeight **/ function fx(o) { if(document.createRange) { var r = document.createRange(); r

How to remove extra characters input from fgets in C?

放肆的年华 提交于 2019-12-08 02:08:22
问题 I heard using gets() is bad in C programming and it's safer using fgets... So I am using fgets. However, I encounter a problem with fgets: I entered too much characters and somehow, it overflows. How to get rid of the extra input characters? char answer[4]; char answer2[4]; fgets(answer,sizeof(answer),stdin); printf("answer: %s\n",answer); fgets(answer2,sizeof(answer2),stdin); printf("answer2: %s\n",answer2); For example, for the first fgets, I enter 123456, the output I get is answer: 123

问题 I am trying to figure out how to get my 'sortable lists' to scroll while I am dragging a list element. The scroll works fine in the list I am dragging from but not in the list I am dragging to . http://jsfiddle.net/jordanbaucke/pacbC/1/ Another question asking a similar thing: jQuery sortable container scroll div with overflow auto PS. Pivotaltracker, www.pivotaltracker.com does this well. 回答1: Old question, but I struggled with this for a few hours today so I figured I'd share what I learned

Section Leak generating horizontal scroll

∥☆過路亽.° 提交于 2019-12-08 00:23:49
问题 I'm trying to create a way to leak an element from it's parent container. I'm using max-width and margin: auto for the container to center. The child element has position: relative and uses left + translateX transform to become centered. The CSS works OK until the page gets scrolling (content height higher than screen height). This vertical scroll also generates horizontal scrolling. I was able to hide it using overflow-x: hidden but i really want to know why i'm getting an horizontal scroll?

html img图片不变形等比例缩放,兼容ie6

好久不见. 提交于 2019-12-08 00:09:50
方法1 img 只定义宽(或高)度可以等比例缩放,外面加个框,设置宽高和 overflow:hidden; 即可 方法2 在img标签里面只设置宽,不设置高,图片就会等比例缩放。 方法3 或者把图片作背景图片。background-position: center center tips: 使用max-width:300px或max-height:100px,即可解决图片比例缩小。但这样存在一个问题,如果按照宽度缩放,但图片过高会超出溢出盒子,这个时候需要对父级使用overflow:hidden隐藏超出图片内容。但是使用max-width或max-height,IE6不支持,我们需要设置个width:expression(this.width > 300 ? "300px" : this.width);或者height:e­xpression(this.height>100?"100px":this.height);。 解决 IE6支持max-height div css解决IE6支持max-width 一般情况下只需要设置好宽度限制,比如这里只设置最大宽度为300px(max-width:300px),然后对父级使用 overflow:hidden 隐藏溢出图片,同时为了兼容IE6我们设置个width:expression(this.width > 300 ? "300px" :

RuntimeWarning: overflow encountered in short_scalars

血红的双手。 提交于 2019-12-07 19:00:29
RuntimeWarning: overflow encountered in short_scalars 在做一个较大数据量的加法时碰到这个问题,按理说python可以自动改变数据类型,把int型变成long甚至longlong,但这里没有。。。 一个可控的方法是用numpy提供的数据类型。(numpy是专门用于科学计算的库,里面提供了大量的方法、数据类型辅助科学计算)比如: 16位的int不够用可以声明为32位的: import numpy as np amplitude_amount = np.int32(0) 他还有诸多类似的数据类型声明,这样就可以自由控制我们对内存和需求的平衡了! a = np.int64(0) b = np.long(0) c = np.longlong(0) 来源: CSDN 作者: iNexus 链接: https://blog.csdn.net/iNexus/article/details/84273656

RuntimeWarning: overflow encountered in ubyte_scalars像素加减运算溢出异常

心不动则不痛 提交于 2019-12-07 19:00:04
用python处理图像时,可能会涉及两幅图像像素值之间的加减运算,这里需要注意的是图像像素值是ubyte类型,ubyte类型数据范围为0~255,若做运算出现负值或超出255,则会抛出异常,下面看一下异常示例: from PIL import Image import numpy as np image1 = np.array(Image.open( "1.jpg" )) image2 = np.array(Image.open( "2.jpg" )) # 异常语句 temp = image1[ 1 , 1 ] - image2[ 1 , 1 ] # 此处如果为负值则溢出 # 正确写法 temp = int (image1[ 1 , 1 ]) - int (image2[ 1 , 1 ]) # 强制为整型再计算就不会溢出了 以上代码即为异常RuntimeWarning: overflow encountered in ubyte_scalars的出现原因以及解决方法,希望能帮助遇到此问题的朋友。 来源: CSDN 作者: Acecai01 链接: https://blog.csdn.net/Acecai01/article/details/80248139

Is this vulnerable to a stack overflow?

試著忘記壹切 提交于 2019-12-07 18:07:31
void gctinp (char *inp, int siz) { puts ("Input value: "); fgets (inp, siz, stdin); printf ("buffer3 getinp read %s", inp); } From what I've read, fgets is supposed to be used when you want to limit the size of input. So this code shouldn't be vulnerable right? It is being called like so: int main (int argc, char *argv[]) { char buf[16]; getinp (buf, sizeof (buf)); display (buf); printf ("buffer3 done\n"); } Thanks for your time. You won't strike buffer overflow problems if you enter more characters than can be safely stored since fgets restricts the input. It also adds a null terminator
