How to overflow-x: visible while overflow-y: scroll

由 让人想犯罪 __ 提交于 2020-01-04 05:20:39
问题 MDN, while talking about overflow, states: MDN Note: Setting one axis to visible (the default) while setting the other to a different value results in visible behaving as auto. So in the following context... overflow-y: scroll/auto overflow-x: visible ... overflow-x: visible behaves as overflow-x: auto , which in turn seems to behave as overflow-x: hidden . Notice in the demo below that half of the orange square is hidden on the Z plane. ::-webkit-scrollbar { display: none; } #grid { width:

问题 When I add an element like h1 with margin: 30px 0; , the margin goes outside the container! I faced this problem many times before, and I solved it by using overflow: hidden I want to figure out what's the problem and why this solution works? Find a JSFiddle here https://jsfiddle.net/LeoAref/zv6c2c2d/ .container { background: #ccc; } .container.overflow { overflow: hidden; } .secTitle { margin: 30px 0; } code { color: blue; } <!-- secTitle margin goes outside the container --> <div class=

html overflow : auto not working on IE

由 自古美人都是妖i 提交于 2020-01-04 02:56:08
问题 I have a div which have a literal which is filled at runtime. The overflow of that div is set to auto but still in IE its showing the contents. However the scrollbar is also appearing but the content is going beyond div and scroll is not working. Any idea? 回答1: Did you set the containing DIV to "position: relative"? See this as a reference: http://snook.ca/archives/html_and_css/position_relative_overflow_ie/ 回答2: Without some example code it's not really possible to tell where the problem is.

浮动元素的父元素高度塌陷问题解决

overflow:hidden; 隐藏溢出，当内容超过其父元素时，可以使用该属性和值将溢出的部分裁剪掉，使页面更加美观 清除浮动，当子元素浮动时，给父元素添加overflow：hidden，按照它的第一个特性，应该将子元素超出的部分截掉，但是因为子元素有浮动，无法裁剪，所有只能由父元素增加高度去包裹住子元素，使得父元素拥有了高度，而这个高度是跟随子元素自适应的高度，这样就把浮动的子元素包含在父元素内了 来源： https://www.cnblogs.com/duanzhenzhen/p/10209771.html

How to clear input buffer after fgets overflow?

由 ∥☆過路亽．° 提交于 2020-01-03 19:30:27
问题 I'm facing a little problem with fgets when the input string exceeds its predefined limit. Taking the example below: for(index = 0; index < max; index++) {printf(" Enter the %d string : ",index+1) if(fgets(input,MAXLEN,stdin)) { printf(" The string and size of the string is %s and %d \n",input,strlen(input) + 1); removeNewLine(input); if(strcmp(input,"end") != 0) { //Do something with input } } Now when I exceed the length MAXLEN and enter a string, I know that the input will append a '\0' at

CSS 教程 - 闭合浮动元素

由 一曲冷凌霜 提交于 2020-01-03 19:29:27
　　按照CSS规范，浮动元素(floats)会被移出文档流，不会影响到块状盒子的布局而只会影响内联盒子(通常是文本)的排列。 　　因此当其高度超出包含容器时，一般父容器不会自动伸长以闭合浮动元素。 　　但是有时我们却需要这种自动闭合行为，具体如何处理呢? 　　有一种做法就是在父容器内再插入一个额外的标签，并令其清除浮动(clear)以撑大父容器。这种方法浏览器兼容性好，没有什么问题，缺点就是需要额外的(而且通常是无语义的)标签，所以我个人不大喜欢。 　　后来又有了一种新的方式，使用 :after 伪类动态的嵌入一个用于清除浮动的元素，这种方法和上一种原理一样，不同的只是把这个额外的内容用 CSS 生成，但考虑到 IE不支持 :after 不得不做了不少的 hack。这种方法兼容性一般，但经过各种 hack 也可以应付不同浏览器了，同时又可以保证 html 比较干净，所以用得还是比较多的。 　　再后来又有人发现将父容器的 overflow 设为除 visible 之外的值就可以在标准兼容浏览器中闭合浮动元素，IE自然又是不支持的，所以这种方法和上一种方法一样都对IE 做了不同处理(具体就是触发layout)，不同的就是overflow 没有 :after 伪类那么麻烦了，缺点也有，overflow 可能会产生一些小冲突。 　　在使用 overflow 之前还有过一种使用 float

1.标准流就是浏览器默认布局的方式，也就是从上往下，从左向右的默认的排班布局的方式。 2.布局方式 　　2.1浮动的本质：解决图片与文字并排的格式问题。 　　*元素浮动后，会脱离标准流，影响其布局。 　　2.1.1未设置浮动前（before）： 　　 　　2.1.2.设置浮动后（after） 　　 　　 1 * { 2 padding: 0; 3 margin: 0; 4 } 5 6 .box1 { 7 width: 50px; 8 height: 40px; 9 background-color: #AFEEEE; 10 border: 2px solid #3C3C3C; 11 float: left; 12 } 13 14 .box2 { 15 width: 300px; 16 height: 300px; 17 background-color: #ADFF2F; 18 border: 2px solid #3C3C3C; 19 20 } 　　*浮动的元素会不占据标准流的空间。但是会影响标准流中的文本的排版。 3.浮动的特性 　　3.1.浮动脱离标准流，不占位置，会影响标准流。浮动只有左右浮动。 　　3.2.浮动的元素A排列位置，跟上一个元素（块级）有关系。如果上一个元素有浮动，则A元素顶部会和上一个元素的顶部对齐；如果上一个元素是标准流

Safari position:sticky not working in an overflow:auto element

由 ぃ、小莉子 提交于 2020-01-03 16:48:09
问题 According to CanIUse, there is a known issue with Safari and position:sticky inside an overflow:auto element: A parent with overflow set to auto will prevent position: sticky from working in Safari However, this is the exact use case that I need. I have a scrollable div, which is subdivided into two columns. The right column should be sticky and never move, even when the entire div is scrolled. The reason I'm using position:sticky on the right column is that I want the user to be able to

Safari (OS X) doesn't emit pointer events on overflowing SVG contents

问题 I need to capture pointer events click and mousemove on shapes that are outside the contents box defined via <SVG> width/height, rendered via overflow: visible . In this example, the circle is rendered properly, and current Chrome, FireFox and IE11 do capture pointer events on the overflowing part, whether or not there's e.g. padding . However, on Safari 10.0.1 OS X, pointer events are not registered, even when I use padding , border , and/or margin , no matter which ones of the possible 8
