如何理解盒模型

前提是你 提交于 2019-12-20 13:50:48
盒模型有两种,W3C 和 IE 盒子模型 1、W3C定义的盒模型包括 margin、border、padding、content ,元素的宽度 width = content 的宽度; 2、IE盒模型与W3C盒模型的唯一区别就是元素的宽度,元素的 width = border+padding+content; 对盒模型的理解 IE定义的盒模型较为合理,所以在css3中新增了 box-sizing ,包含两个属性 content-box 和 border-box ; 1)content-box 元素的 width = content; 2)border-box 元素的 width = border + padding + content; 更多理解 对于行内元素 margin-top/margin-bottom 对于上下元素无效,margin-left/margin-righ有效; 对于相邻的块级元素 margin-top 和 margin-bottom 两者叠加按照一定的规则; 1)都是整数 margin 值取两者的最大值; 2)都是负数 margin 值取最小值; 3)两者正负相反,margin 值取两者之和;     来源: https://www.cnblogs.com/wangqian888/p/11973458.html

How to use (top) margin with CSS3 drop down menu?

∥☆過路亽.° 提交于 2019-12-20 05:50:35
问题 I am trying to create a drop down menu completely in CSS3. For the most part I have accomplished what I wanted, but for some reason I can't seem to add margin-top: 10px; to drop down menu, as I don't want it touching the main link. It seems to deactivate the hover when it hits the margin? I have posted a working example with no margin on jsFiddle: http://jsfiddle.net/J5QSv/ This is with the margin-top: 10px; , and does not work: http://jsfiddle.net/RastaLulz/J5QSv/2/ As you can see, that

HTML第13章:CSS代码缩写,占用更少的带宽

13-1 盒模型代码简写 还记得在讲盒模型时外边距(margin)、内边距(padding)和边框(border)设置上下左右四个方向的边距是按照顺时针方向设置的: 上右下左 。具体应用在margin和padding的例子如下: margin : 10 px 15 px 12 px 14 px ; /*上设置为10px、右设置为15px、下设置为12px、左设置为14px*/ 通常有下面三种缩写方法: 1、如果top、right、bottom、left的值相同,如下面代码: margin : 10 px 10 px 10 px 10 px ; 可缩写为: margin : 10 px ; 2、如果top和bottom值相同、left和 right的值相同,如下面代码: margin : 10 px 20 px 10 px 20 px ; 可缩写为: margin : 10 px 20 px ; 3、如果left和right的值相同,如下面代码: margin : 10 px 20 px 30 px 20 px ; 可缩写为: margin : 10 px 20 px 30 px ; 注意:padding、border的缩写方法和margin是一致的。 13-2颜色值缩写 关于颜色的css样式也是可以缩写的,当你设置的颜色是16进制的色彩值时,如果每两位的值相同,可以缩写一半。

wpf - how do I apply same margins to all elements in a panel?

半世苍凉 提交于 2019-12-20 05:17:14
问题 Is there a way of automatically tells all children items (e.g. labels, textboxes etc) to have a margin of 5, within a panel (e.g. dockpanel)? i.e. as opposed to having to set the margin for each element separately - also noting setting the margin on the panel itself is no good as then the panel has the margin not the elements. by the way - I note there doesn't seem to be a PADDING element on the DockPanel (which would have helped) 回答1: I believe the answer is "no". Margin is not inheritable

CSS的inline、block与inline-block

岁酱吖の 提交于 2019-12-20 00:00:31
基本知识点 行内元素一般是内容的容器,而块级元素一般是其他容器的容器,行内元素适合显示具体内容,而块级元素适合做布局。 块级元素(block): 独占一行,对宽高的属性值生效;如果不给宽度,块级元素就默认为浏览器的宽度,即就是100%宽。 行内元素(inline): 可以多个标签存在一行,对宽高属性值不生效,完全靠内容撑开宽高。 行内块元素(inline-block): 结合的行内和块级的优点,既可以设置长宽,可以让padding和margin生效,又可以和其他行内元素并排。 其中 img和input为行内块元素 。 行内元素与块状元素之间的转换: float: 当把行内元素设置完float:left/right后,该行内元素的display属性会被赋予block值,且拥有浮动特性。行内元素去除了之间的莫名空白。 <head> <meta charset="UTF-8"> <title>测试</title> <style type="text/css"> p{ background-color: red; height: 500px; width: 30%; padding: 20px; margin: 20px; float: left;} div{ background-color: green; height: 50px; width: 40%; padding: 20px;
