CSS3与页面布局学习总结(二)——Box Model、边距折叠、内联与块标签、CSSReset

一、盒子模型(Box Model)

盒子模型也有人称为框模型,HTML中的多数元素都会在浏览器中生成一个矩形的区域,每个区域包含四个组成部分,从外向内依次是:外边距(Margin)、边框(Border)、内边距(Padding)和内容(Content),其实盒子模型有两种,分别是 ie 盒子模型和标准 w3c 盒子模型,加上了doctype声明,让所有浏览器都会采用标准 w3c 盒子模型去解释你的盒子。当设置一个元素的样式如下:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>盒子模型</title>
<style type="text/css">
#box{
width: 100px;
height: 100px;
margin: 20px;
padding: 20px;
border: 10px solid blue;
}
</style>
</head>
<body>
<div id="box">
Box Model
</div>
</body>
</html>

运行结果:

1.1、宽度测试

计算最大宽度,示例如下:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>盒子模型</title>
<style type="text/css">
#box{
width: 800px;
padding: 10px;
border: 5px solid blue;
margin: 10px;
}
.sbox{
display: inline-block;
padding: 10px;
margin: 10px;
border: solid 10px coral;
background: lightblue;
width: ?;
}
</style>
</head>
<body>
<div id="box">
<div class="sbox">Left</div><div class="sbox">Right</div>
</div>
</body>
</html>

要达到如下效果,请问?处最大可以设置为多少像素?

CSS3与页面布局学习总结(二)——Box Model、边距折叠、内联与块标签、CSSReset

答案:

340px

1.2、溢出测试

代码如下:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>盒子模型</title>
<style type="text/css">
#box{
width: 800px;
padding: 10px;
border: 5px solid blue;
margin: 10px;
height: 100px;
}
#box #innerBox{
background: lightblue;
height:50px ;
width: 100%;
padding: 10px;
margin: 10px;
border: 10px solid lightcoral;
}
</style>
</head>
<body>
<div id="box">
<div id="innerBox">
innerBox
</div>
</div>
</body>
</html>

请问运行时innerBox是否会超出box,如果会,超出多少?

可见部分=850-815=35,还有10个margin不可见,45px

CSS3与页面布局学习总结(二)——Box Model、边距折叠、内联与块标签、CSSReset

如果不想让innerBox超出,则应该删除其100%的宽度设置,去掉width:100%,一般不要设置,多此一举。

1.3、box-sizing属性

设置或检索对象的盒模型组成模式

content-box: padding和border不被包含在定义的width和height之内。对象的实际宽度等于设置的width值和border、padding之和,即 ( Element width = width + border + padding,但占有页面位置还要加上margin ) 此属性表现为标准模式下的盒模型。

示例:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>盒子模型</title>
<style type="text/css">
#box{
width: 100px;
height: 100px;
padding: 10px;
border: 10px solid blue;
margin: 10px;
}
</style>
</head>
<body>
<div id="box">
Box Model
</div>
</body>
</html>

运行结果:

CSS3与页面布局学习总结(二)——Box Model、边距折叠、内联与块标签、CSSReset

因为默认就是为content-box所以这里没有直接设置,占用宽度为160px;

border-box: padding和border被包含在定义的width和height之内。对象的实际宽度就等于设置的width值,即使定义有border和padding也不会改变对象的实际宽度,即 ( Element width = width ) 此属性表现为怪异模式下的盒模型。

示例代码:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>盒子模型</title>
<style type="text/css">
#box{
width: 100px;
height: 100px;
padding: 10px;
border: 10px solid blue;
margin: 10px;
box-sizing: border-box; /*在上一个例子中添加的*/
}
</style>
</head>
<body>
<div id="box">
Box Model
</div>
</body>
</html>

运行结果:

CSS3与页面布局学习总结(二)——Box Model、边距折叠、内联与块标签、CSSReset

当box-sizing: border-box时的宽度设置会包含border与padding,但不包含margin,但margin也会占用位置。

1.4、利用CSS画图

示例代码:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>盒子模型 - 三角形</title>
<style type="text/css">
#box{
width: 0;
height: 0;
border: 100px solid blue;
border-color: blue transparent transparent transparent;
/*设置边线的颜色,transparent表示透明的颜色,按上右下左的顺时钟方向*/
}
</style>
</head>
<body>
<div id="box">
</div>
</body>
</html>

运行结果:

二、边距折叠

2.1、概要

外边距折叠:相邻的两个或多个外边距 (margin) 在垂直方向会合并成一个外边距(margin)
相邻:没有被非空内容、padding、border 或 clear 分隔开的margin特性. 非空内容就是说这元素之间要么是兄弟关系或者父子关系,如:

示例代码:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<style type="text/css">
#div1{
border: 3px solid blue;
height: 200px;
background: lightcoral;
}
#div2{
height: 100px;
background: lightgreen;
margin-top: 20px;
}
#div3{
height: 50px;
width: 50%;
background: lightblue;
margin-top: 20px;
}
</style>
</head>
<body>
<div id="div1">
<div id="div2">
<div id="div3">
</div>
</div>
</div>
</body>
</html>

运行结果:

CSS3与页面布局学习总结(二)——Box Model、边距折叠、内联与块标签、CSSReset

因为div2与div3的外边距是相邻的(是父子关系的相邻),当div2 margin-top为20,div3的margin-top也为20,此时div2与div3的外边距会合并,就是折叠。

如果想让div3的margin-top生效,可以破坏相邻的限制,示例:

<!DOCTYPE html>
<html> <head>
<meta charset="UTF-8">
<title></title>
<style type="text/css">
#div1{
border: 3px solid blue;
height: 200px;
background: lightcoral;
} #div2{
height: 100px;
background: lightgreen;
margin-top: 20px;
border: 1px solid green;
} #div3{
height: 50px;
width: 50%;
background: lightblue;
margin-top: 20px;
}
</style>
</head> <body>
<div id="div1">
<div id="div2">
<div id="div3">
</div>
</div>
</div>
</body> </html>

运行结果:

2.2、垂直方向外边距合并计算

a)、参加折叠的margin都是正值:取其中 margin 较大的值为最终 margin 值。

示例:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>边距折叠</title>
</head>
<body>
<div style="height:90px; margin-bottom:99px; width:90px; background-color: red;">X</div>
<div style="height:90px; margin-top:100px; width:90px; background-color: blue;">Y</div>
</body>
</html>

运行结果:

CSS3与页面布局学习总结(二)——Box Model、边距折叠、内联与块标签、CSSReset

b)、参与折叠的 margin 都是负值:取的是其中绝对值较大的,然后,从 0 位置,负向位移。
示例:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>边距折叠</title>
</head>
<body>
<div style="height:90px; margin-bottom:-10px; width:90px; background-color: red;">X</div>
<div style="height:90px; margin-top:-30px;width:70px; background-color: blue;">Y</div>
</body>
</html>

结果:

CSS3与页面布局学习总结(二)——Box Model、边距折叠、内联与块标签、CSSReset

c)、参与折叠的 margin 中有正值,有负值:先取出负 margin 中绝对值中最大的,然后,和正 margin 值中最大的 margin 相加。
示例:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>参与折叠的 margin 中有正值,有负值</title>
</head>
<body>
<div style="height:90px; margin-bottom:-30px; width:90px; background-color: red;">X</div>
<div style="height:90px; margin-top:30px;width:70px; background-color: blue;">Y</div>
</body>
</html>

运行结果:

2.3、边距折叠简单应用

示例:

<!DOCTYPE html>
<html> <head>
<meta charset="UTF-8">
<title></title>
<style type="text/css">
#div0 {
width: 490px;
height: 90px;
border: 5px solid dodgerblue;
margin: 0 auto;
padding: 10px;
} #div0 .subItem {
float: left;
width: 90px;
height: 90px;
background: orangered;
margin-right: 10px;
}
</style>
</head> <body>
<div id="div0">
<div style="margin-right: -10px;">
<div class="subItem">1</div>
<div class="subItem">2</div>
<div class="subItem">3</div>
<div class="subItem">4</div>
<div class="subItem">5</div>
</div>
</div>
</body> </html>

三、内联与块级标签

3.1、行内标签与块标签区别

html中的标签默认主要分为两大类型,一类为块级元素,另一类是行内元素,许多人也把行内称为内联,所以叫内联元素,其实就是一个意思。为了很好的布局,必须理解它们间的区别,区别如下:

CSS3与页面布局学习总结(二)——Box Model、边距折叠、内联与块标签、CSSReset

常用的块级有:div,p,h1~h6,ul,li,dl,dt,dd...  常用的行内有:span,font,b,u,i,strong,em,a,img,input,其中img和input为行内块元素。

更多块级与内联元素:

内联元素(行内元素)内联元素(inline element)
a - 超链接
abbr - 缩写
acronym - 首字
bdo - bidi override
big - 大字体
br - 换行
cite - 引用
code - 计算机代码(在引用源码的时候需要)
dfn - 定义字段
em - 强调
i - 斜体
img - 图片
input - 输入框
kbd - 定义键盘文本
label - 表格标签
q - 短引用
samp - 定义范例计算机代码
select - 项目选择
small - 小字体文本
span - 常用内联容器,定义文本内区块
strike - 中划线
strong - 粗体强调
sub - 下标
sup - 上标
textarea - 多行文本输入框
tt - 电传文本
u - 下划线
var - 定义变量 块元素(block element)

noframes - frames可选内容,(对于不支持frame的浏览器显示此区块内容
noscript - )可选脚本内容(对于不支持script的浏览器显示此内容)
ol - 排序表单
p - 段落
pre - 格式化文本
table - 表格
ul - 非排序列表 可变元素,可变元素为根据上下文语境决定该元素为块元素或者内联元素。
applet - java applet
button - 按钮

map - 图片区块(map)
object - object对象
script - 客户端脚本

行内标签与块标签特性示例:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>块级标签与行内标签</title>
<style type="text/css">
#div1,
#div2 {
background: lightblue;
}
span {
width: 100px;
/*无效*/
height: 20px;
/*无效*/
margin: 20px;
/*水平方向有效,垂直方向无效*/
padding: 20px;
/*水平方向有效,垂直方向无效*/
}
#div3{
width: 500px;
border: 1px solid #ADD8E6;
word-break: break-all;
}
</style>
</head> <body>
<h2>块级标签与行内标签</h2>
<div id="div1">div1</div>
<div id="div2">div2</div>
<div id="div3">
<span id="span1">span1</span>
<span id="span2">span2</span>
<span id="span3">span3</span>
<span id="span4">spanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspanspan4</span>
</div>
</body>
</html>

使用display设置元素的显示方式

语法如下:

display:none | inline | block | list-item | inline-block | table | inline-table | table-caption | table-cell | table-row | table-row-group | table-column | table-column-group | table-footer-group | table-header-group | run-in | box | inline-box | flexbox | inline-flexbox | flex | inline-flex
默认值:inline

none: 隐藏对象。与visibility属性的hidden值不同,其不为被隐藏的对象保留其物理空间
inline: 指定对象为内联元素。
block: 指定对象为块元素。
list-item: 指定对象为列表项目。
inline-block: 指定对象为内联块元素。(CSS2)
table: 指定对象作为块元素级的表格。类同于html标签<table>(CSS2)
inline-table: 指定对象作为内联元素级的表格。类同于html标签<table>(CSS2)
table-caption: 指定对象作为表格标题。类同于html标签<caption>(CSS2)
table-cell: 指定对象作为表格单元格。类同于html标签<td>(CSS2)
table-row: 指定对象作为表格行。类同于html标签<tr>(CSS2)
table-row-group: 指定对象作为表格行组。类同于html标签<tbody>(CSS2)
table-column: 指定对象作为表格列。类同于html标签<col>(CSS2)
table-column-group: 指定对象作为表格列组显示。类同于html标签<colgroup>(CSS2)
table-header-group: 指定对象作为表格标题组。类同于html标签<thead>(CSS2)
table-footer-group: 指定对象作为表格脚注组。类同于html标签<tfoot>(CSS2)
run-in: 根据上下文决定对象是内联对象还是块级对象。(CSS3)
box: 将对象作为弹性伸缩盒显示。(伸缩盒最老版本)(CSS3)
inline-box: 将对象作为内联块级弹性伸缩盒显示。(伸缩盒最老版本)(CSS3)
flexbox: 将对象作为弹性伸缩盒显示。(伸缩盒过渡版本)(CSS3)
inline-flexbox: 将对象作为内联块级弹性伸缩盒显示。(伸缩盒过渡版本)(CSS3)
flex: 将对象作为弹性伸缩盒显示。(伸缩盒最新版本)(CSS3)
inline-flex: 将对象作为内联块级弹性伸缩盒显示。(伸缩盒最新版本)(CSS3)

  • 如果display设置为none,floatposition属性定义将不生效;
  • 如果position既不是static也不是relative或者float不是none或者元素是根元素,当display:inline-table时,display的计算值为table;当display:inline | inline-block | run-in | table-* 系时,display的计算值为block,其它情况为指定值;
  • IE6,7支持inline元素转换成inline-block,但不支持block元素转换成inline-block,所以非inline元素在IE6,7下要转换成inline-block,需先转换成inline,然后触发hasLayout,以此来获得和inline-block类似的效果;你可以这样:

  • 全兼容的inline-block:

    div {
    display: inline-block;
    *display: inline;
    *zoom: 1;
    }

Basic Support包含值:none | inline | block | list-item | inline-block
table系包含值:table | inline-table | table-caption | table-cell | table-row | table-row-group | table-column | table-column-group | table-footer-group | table-header-group
IE6,7只支持inline元素设置为inline-block,其它类型元素均不可以

3.2、隐藏

可以使用3种办法让元素隐藏:

a)、使用CSS的display:none,不会占有原来的位置

b)、使用CSS的visibility:hidden,会占有原来的位置

c)、使用HTML5中的新增属性hidden="hidden",不会占有原来的位置

示例:

<!DOCTYPE html>
<html> <head>
<meta charset="UTF-8">
<title>隐藏</title>
<style type="text/css">
div{
width: 100px;
height: 100px;
border: 2px solid blue;
margin: 10px;
font-size: 30px;
}
#div1
{
display: none;
}
#div2{
visibility: hidden;
}
</style>
</head> <body>
<div id="div0">div0</div>
<div id="div1">div1</div>
<div id="div2">div2</div>
<div id="div3" hidden="hidden">div3</div>
<div id="div4">div4</div>
</body> </html>

运行结果:

3.3、行内块标签

当元素的样式display为inline-block属性时就被设置成了行内块标签,同时拥有行内标签与块标签的特性,不再占整行;可以设置宽度,高度;padding与margin都有效。

示例:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>inline-block</title>
<style type="text/css">
div,span{
width: 100px;
height: 100px;
border: 2px solid blue;
font-size: 30px;
display: inline-block;
margin: 10px;
padding: 10px;
}
</style>
</head>
<body>
<div id="div0">div0</div><div id="div1">div1</div><div id="div2">div2</div><div id="div3">div3</div><div id="div4">div4</div>
<p>
<span>span1</span><span>span2</span><span>span3</span>
</p>
</body>
</html>

运行结果:

3.4、菜单示例

使用display属性结合图片实现网页中的图片菜单:

<!DOCTYPE html>
<html> <head>
<meta charset="UTF-8">
<title>menu</title>
<style type="text/css">
* {
margin: 0;

四、重置浏览器默认样式

下图是同一段HTML在3个不同内核的浏览器中打开的效果,你发现有不一样吗?很明显有区别,这就是浏览器的默认样式,每一个浏览器会设置user agent stylesheet,比如默认字体大小为16px。浏览器的默认样式会给我们带一定的麻烦,比如在计算元素的大小时默认样式会设置padding与margin值,不同的浏览器可能设置的不一样,就会出现误差,重置浏览器样式就是让您可以在一张白纸上写字。更多CSS中的bug:https://lizheming.github.io/wtf-html-css/

CSS3与页面布局学习总结(二)——Box Model、边距折叠、内联与块标签、CSSReset

最开始会使用一个简单的办法,如 :

            *
{
margin:;
padding:;
}

虽然能全部重置,但由于性能较低,不推荐使用。因为*需要遍历整个DOM树,当页面节点较多时,会影响页面的渲染性能。

4.1、CSSReset

每种浏览器都有一套默认的样式表,即user agent stylesheet,网页在没有指定的样式时,按浏览器内置的样式表来渲染。这是合理的,像word中也有一些预留样式,可以让我们的排版更美观整齐。不同浏览器甚至同一浏览器不同版本的默认样式是不同的。但这样会有很多兼容问题,CSSReset可以将所有浏览器默认样式设置成一样。

4.1.1、MT css reset

/*MT css reset*/
body,dl,dd,p,h1,h2,h3,h4,h5,h6{margin:;}
h1,h2,h3,h4,h5,h6{font-size:100%} /*继承body设定的字体大小*/
/* 根据屏幕大小改变文字大小 */
html{font-size:20px;} /*chorme下设置为10px无效,推荐设置为20px,1rem=20px*/
@media screen and (max-width:768px){ /*手机屏幕*/
html{font-size: 15px;}
}
@media screen and (min-width: 768px) and (max-width:992px){ /*平板屏幕*/

4.2、normalize

也许有些cssreset过于简单粗暴,有点伤及无辜,normalize是另一个选择。bootstrap已经引用该css来重置浏览器默认样式,比普通的cssreset要精细一些,保留浏览器有用的默认样式,支持包括手机浏览器在内的超多浏览器,同时对HTML5元素、排版、列表、嵌入的内容、表单和表格都进行了一般化。

Normalize.css和传统Reset的区别:
a)、Normalize.css 保护了有价值的默认值
Reset通过为几乎所有的元素施加默认样式,强行使得元素有相同的视觉效果。相比之下,Normalize.css保持了许多默认的浏览器样式。这就意味着你不用再为所有公共的排版元素重新设置样式。当一个元素在不同的浏览器中有不同的默认值时,Normalize.css会力求让这些样式保持一致并尽可能与现代标准相符合。

b)、Normalize.css 修复了浏览器的bug
它修复了常见的桌面端和移动端浏览器的bug。这往往超出了Reset所能做到的范畴。关于这一点,Normalize.css修复的问题包含了HTML5元素的显示设置、预格式化文字的font-size问题、在IE9中SVG的溢出、许多出现在各浏览器和操作系统中的与表单相关的bug。

4.3、base css

如果说css reset是为了重置浏览器的默认样式,则base css是准备一些通用的css提高开发效率,如.fl表示float left,左浮动,也有人移为common.css,也有把该部分内容与cssreset合并的,这样可以减少http请求,简单的示例如下:

.clear {
clear:both
}
.fr {
float:right
}
.fl {
float:left
}
.block {
display:block;
text-indent:-999em
}
.w100{width: 100px;};
.w200{width: 200px;};
.w300{width: 300px;};
.w400{width: 400px;};
.w500{width: 500px;};
/*....*/
.wp100{width: 100%;};
.wp50{width: 50%;};
.wp33{width: 33%;};
.wp25{width: 25%;};
.wp20{width: 20%;};
