Internet Explorer CSS property “filter” ignores overflow:visible

由 余生颓废 提交于 2019-12-21 03:41:16
问题 Apparently Internet Explorer (up to version 8 at least) ignores overflow:visible when applying filter (e.g. for opacity), causing anything outside the filtered element to be clipped as if overflow:hidden were used. Are there any workarounds to this behavior ? The sample code below shows how child is clipped by container – only its right and bottom borders are visible. <style type="text/css"> #container { position:absolute; left:100px; top:100px; width:100px; height:100px; border:1px solid

Why does overflow-x:hidden clip my descenders?

问题 I would like to have a title element with overflow-x:hidden and overflow-y:visible . However, for some reason the overflow-y property does not seem to be obeyed. You can observe this here (tested on Chrome and Firefox): http://jsfiddle.net/YgsAw/3/ In that demo, I expect to see "jjjjj", but instead the j's are cut off and look more like 1's. If I set overflow-x:visible on the h1 tag then suddenly the full height of the text is visible, but setting overflow-x:hidden makes it clipped. I would

How do I detect overflow while multiplying two 2's complement integers?

由 久未见 提交于 2019-12-21 03:18:20
问题 I want to multiply two numbers, and detect if there was an overflow. What is the simplest way to do that? 回答1: Multiplying two 32 bit numbers results in a 64 bit answer, two 8s give a 16, etc. binary multiplication is simply shifting and adding. so if you had say two 32 bit operands and bit 17 set in operand A and any of the bits above 15 or 16 set in operand b you will overflow a 32 bit result. bit 17 shifted left 16 is bit 33 added to a 32. So the question again is what are the size of your

Does INT_MIN % -1 produce undefined behavior?

由 牧云@^-^@ 提交于 2019-12-21 03:13:20
问题 gcc generates floating code that raises SIGFPE for the following code: #include <limits.h> int x = -1; int main() { return INT_MIN % x; } However I can find no statement in the standard that this code invokes undefined or implementation-defined behavior. As far as I can tell, it's required to return 0. Is this a bug in gcc or am I missing some special exception the standard makes? 回答1: You are probably right that this can be considered as a bug in the actual standard. The current draft

Why overflow:hidden expands parent element (containing floated child elements)?

由 半世苍凉 提交于 2019-12-21 01:58:12
问题 In short: Basically, I just want to know why overfow:hidden explands the container containing a floated item. Shouldnt it hide the overflowing element like in this image http://css-tricks.com/wp-content/csstricks-uploads/css-overflow-hidden.png why does it do this instead http://css-tricks.com/wp-content/csstricks-uploads/overflow-float.png Long version: Non-positioned, non-floated, block-level elements act as if the floated element is not there, since the floated element is out of flow in

第一回 overflow基本属性 overflow基本属性 visibel hidden scroll auto inherit overflow-x和overflow-y overflow-x和overflow-y设置一样的值，等同于overflow。如果不同，其中一个赋予visibel，auto，另一个赋值visibel，auto ，hidden。则会被重置为auto。 作用的前提 1.非display：inline水平！ 2.对应方位的尺寸限制，width/height/max-width/max-height/absolute拉伸 overflow：visibel妙用 IE7浏览器下，文字越多，按钮两侧padding留白就越大。给所有按钮添加css样式 overflow：visible 第二回：overflow与滚动条 滚动条出现的条件 1.overflow：auto/overflow:scroll 有些元素自带滚动条 <html> <textarea> body/html与滚动条 无论什么浏览器，默认滚动条均来自html!而不是body标签 ie8+ html{overflow:auto} 所以，如果我们想要去除页面默认滚动条，只需要：html{overflow:hidden} body/html与滚动条-js与滚动高度 兼容写法 var st = document

Move div with dynamic height out of its parent container

由 浪子不回头ぞ 提交于 2019-12-20 07:38:05
问题 I'm trying to move a div with a dynamically changing height out of it's parent div and back in. The problem is the dynamically height, otherwise I could easily set the negative height as the bottom value. For now I just set a large negative number of pixels as the bottom value, but it isn't very nice and does not solve the problem properly. (logically this happens for small numbers: fiddle) Hopefully the example below clarifies what I try to do. I was thinking about using transforms instead,

Why is my swf taking up more space than it actually is?

问题 I created a simple flash animation to work like a slideshow on the front page of my website. Because the container was 640 by 500 with a padding of 10 px all around, I made the swf 620 by 480 to fit perfectly. For some strange reason, whenever I preview my site or upload it to my host server, scroll bars appear, indicating that the animation is slightly too big. I can't understand what I'm doing wrong. Here's the HTML pertaining to the animation and the container: <div class="mainspace">
