【1】IE6-浏览器下子元素能撑开父级设置好的宽高
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}ul{ margin: 0; padding: 0; list-style: none;}.list{ height: 300px; width: 300px; background-color: #ccc; border: 10px solid black;}.in{ height: 400px; width: 100px; background-color: red; margin: 10px; padding: 10px; border: 1px solid black;}</style></head><body><div class="box" id="box"> <ul class="list" id="list"> <li class="in" id="test">test</li> </ul> </div></body> </html>
【2】IE6-浏览器下最小高度问题,设置(0-15px)高度小于等于15px的元素,在IE6下会被当作15px来处理
【解决】
[1]设置font-size为0,但最小高度为2px
[2]设置overflow:hidden,但最小高度为1px
[3]要想实现最小高度为0,只能是不设置高度
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}.box{ height: 0px; background-color: #ccc;}</style></head><body><div class="box" id="box"></div></body> </html>
【1】IE6-浏览器下1px的点线边框,点线会变成虚线
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}.box{ height: 300px; width: 300px; background-color: #ccc; border: 1px dotted black;}</style></head><body><div class="box" id="box"></div></body> </html>
【2】标准下背景会延伸到边框区,而IE7-浏览器下背景只延伸到padding区
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}.box{ height: 300px; width: 300px; background-color:#ccc; border: 10px dashed red;}</style></head><body><div class="box" id="box"></div></body> </html>
【3】在IE10-浏览器下被标签包含的元素会产生边框
【解决】给图片设置{border: none}
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}img{ height: 300px; width: 300px; background-color:#ccc;}</style></head><body><a href="#"><img src="#" alt="IE浏览器下常见的CSS兼容问题_html/css_WEB-ITnose" ></a></body> </html>
【1】IE7-浏览器下父级有边框,无法阻止子元素的上下margin值传递
【解决】触发父级的haslayout
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}ul{ margin: 0; padding: 0; list-style: none;}.list{ border: 10px solid black; background-color: red;}.in{ height: 100px; width: 100px; margin-top: 50px; background-color: blue;}</style></head><body><ul class="list"> <li class="in"></li></ul></body> </html>
【2】IE7-浏览器下不设置文档声明会导致怪异盒模型解析。在怪异盒模型下内容宽=width-2*padding-2*borderWidth
<html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}.box{ height: 100px; width: 100px; border: 40px solid black; background-color: red;}</style></head><body><div class="box" id="box"></div></body> </html>
【3】IE6-浏览器下使用margin负值,使元素移出父级,移出部分会被父级裁掉
【解决】给子级加相对定位relative
<html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}ul{ margin: 0; padding: 0; list-style: none;}.list{ margin-left: 100px; height: 300px; width: 300px; background-color: #ccc;}.in{ margin-left: -30px; height: 100px; width: 100px; background-color: red;}</style></head><body><ul class="list"> <li class="in"></li></ul></body> </html>
【1】(li的4px空隙bug)IE7-浏览器下,li本身没浮动,但内容有浮动,li下边会多出4px的空隙
【解决】
[1]给li加浮动
[2]设置vertical-align
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}ul{ margin: 0; padding: 0; list-style: none;}.list{ width: 200px; background-color: lightgreen;}.in{ height: 100px; background-color: lightblue;}</style></head><body><ul class="list"> <li class="in"> <span style="max-width:90%">1231</span> </li> <li class="in"> <span style="float: left">1232</span> </li></ul></body> </html>
【2】(li下的4px间隙和最小高度共存的问题)IE7浏览器下,当li下的4px间隙问题和最小高度问题共存的时候,设置垂直对齐方式无效
【解决】给li加浮动
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}ul{ margin: 0; padding: 0; list-style: none;}.list{ width: 200px; background-color: lightgreen;}.in{ height: 12px; background-color: lightblue; overflow: hidden; vertical-align: middle;}.span{ float: left;}</style></head><body><ul class="list"> <li class="in"> <span class="span">1231</span> </li> <li class="in"> <span class="span">1232</span> </li></ul></body> </html>
【3】(li的3px空隙bug)IE7-浏览器下li有高度或宽度或zoom:1,且仅包含内联元素,且内联元素被设置为display:block,li下会多出3px的垂直间距
【解决】触发li中子元素的haslayout
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}ul{ margin: 0; padding: 0; list-style: none;}.list{ width: 200px; background-color: lightgreen;}.in{ height: 100px; background-color: lightblue;}.span{ display: block;}</style></head><body><ul class="list"> <li class="in"> <span class="span">1231</span> </li> <li class="in"> <span class="span">1232</span> </li></ul></body> </html>
【1】(3pxbug)在IE6-浏览器下浮动元素和非浮动元素相邻时,会出现3px像素的空隙
【解决】
[1]使用CSShack,给浮动元素设置相反方向的-3px的margin值,将非浮动元素的相应方向的margin设为0(加IE6前缀)
[2]去掉非浮动元素的margin值,加浮动。
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}.box{ width: 100px; height: 100px;}#box1{ float: left; background-color: red; _margin-right:-3px; border-right: 1px solid green;}#box2{ margin-left: 100px; _margin-left: 0; border:1px solid black; background-color: blue; }</style></head><body><div class="box" id="box1"></div><div class="box" id="box2"></div></body> </html>
【2】IE6-下父元素浮动后,且子元素设置了高度,如果父元素不设置宽度,宽度会撑满整行
【解决】
[1]给浮动的父元素设置宽度
[2]给子元素设置宽度
[3]给子元素设置浮动
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}ul{ margin: 0; padding: 0; list-style: none;}.list{ float: left; background-color: green;}.in{ height: 100px; background-color: yellow;}</style></head><body><ul class="list"> <li class="in">我是内容</li></ul></body> </html>
【3】(浮动折行)在IE7-浏览器下,如果两个元素一个右浮动,一个不浮动。浮动元素会折到下一行
【解决】
[1]给不浮动的元素也加浮动
[2]在HTML中先放右浮动的元素
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}ul{ margin: 0; padding: 0; list-style: none;}.list{ width: 500px; background-color: lightgreen; overflow: hidden;}.in{ width: 100px; height: 100px;}.in1{ background-color: lightyellow;}.in2{ background-color: lightblue; float: right;}</style></head><body><div class="list"> <span class="in in1">我是不浮动</span> <span class="in in2">我是右浮动</span></div></body> </html>
【4】(双边距bug)IE6-浏览器下块元素有浮动,且有横向的margin值。若仅有左margin,最左边的浮动的块元素的左margin会放大成两倍。若仅有右margin,最右边的浮动的块元素的右margin会放大成两倍。若左右都有,最左边的左margin和最右边的右margin会放大成两倍。
【解决】给块元素设置display:inline
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}ul{ margin: 0; padding: 0; list-style: none;}.list{ float: left; background-color: #ccc;}.in{ float:left; width: 100px; height: 100px;}.in1{ background-color: lightgreen; margin-left: 50px;}.in2{ background-color: lightyellow;}.in3{ background-color: lightblue; margin-right: 50px;}</style></head><body><ul class="list"> <li class="in in1"></li> <li class="in in2"></li> <li class="in in3"></li></ul></body> </html>
【5】(margin-bottomBUG)在IE7-浏览器下父级宽度和每行元素的宽度之和相差超过3px时,或者有不满行的情况,最后一行的margin-bottom失效
【解决】尽量不要用margin-bottom,而用margin-top代替
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}ul{ margin: 0; padding: 0; list-style: none;}.list{ width: 350px; overflow: hidden; background-color: #ccc;}.in{ float:left; width: 100px; height: 100px; margin-bottom: 10px; margin-right: 10px; background-color: lightgreen;}</style></head><body><ul class="list"> <li class="in"></li> <li class="in"></li> <li class="in"></li> <li class="in"></li> <li class="in"></li></ul></body> </html>
【6】(文字溢出bug)IE6-浏览器下两个浮动元素(浮动元素不能是li)一个左浮无宽度,另一个右浮动宽度与父级宽度相差不超过3px,浮动元素中间有注释或者内联元素,文字就被复制
【解决】
[1]将注释去掉
[2]将内联元素变成块元素
[3]内联元素及注释整个用
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}ul{ margin: 0; padding: 0; list-style: none;}.list{ width: 200px;}.in1{ float:left;}.in2{ float:right; width:198px;}</style></head><body><div class="list"> <div class="in1"></div> <!-- 我是--><span></span><!-- 我是 --><!-- 我是 --> <div class="in2">多出来的一头猪吗</div></div></body> </html>
【1】在IE7-浏览器下子元素有相对定位,父级的overflow无效
【解决】给父级也设置相对定位
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}ul{ margin: 0; padding: 0; list-style: none;}.list{ background-color: lightgreen; width: 200px; height: 100px; overflow: auto;}.in{ position: relative; width: 100px; height: 300px; background-color: lightblue;}</style></head><body><ul class="list"> <li class="in"></li></ul></body> </html>
【2】在IE6-浏览器下浮动元素和绝对定位元素是并列关系,且浮动元素设置margin-left和width的和正好等于父元素的宽度,这时绝对定位元素会消失
【解决】给定位元素外面包一个div
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}ul{ margin: 0; padding: 0; list-style: none;}.list{ background-color: lightgreen; width: 200px; height: 100px;}.in1{ position: absolute; top: 0; left: 0; width: 100px; height: 100px; background-color: lightblue;}.in2{ float: left; margin-left: 100px; display: inline; width: 100px; height: 100px; background-color: pink; }</style></head><body><ul class="list"> <li class="in1">定位元素</li> <li class="in2">浮动元素</li></ul></body> </html>
【3】在IE6-浏览器下绝对定位元素的父级元素的宽度为奇数时,元素的right会有1px的偏差;高度为奇数时,元素的bottom会有1px的偏差
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}ul{ margin: 0; padding: 0; list-style: none;}.list{ position: relative; background-color: black; width: 199px; height: 199px;}.in{ position: absolute; right: 0; bottom: 0; width: 100px; height: 100px; background-color: lightblue;}</style></head><body><ul class="list"> <li class="in">定位元素</li></ul></body> </html>
【1】IE6-浏览器下label标签只支持for属性,不支持仅仅包含的写法
【解决】使用for属性
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title></head><body><label><input type="checkbox">label测试文字</label></body> </html>
【2】(input空隙问题)当input元素被div包围时,IE6-浏览器下它们之间上下会各多出1px的空隙;而IE7、8浏览器下它们之间的上边会多出1px的空隙
【解决】给input加浮动
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}input{ margin: 0; padding: 0; border: none;}.box{ width: 202px; height: 32px; border: 1px solid black; background-color: red;}.ipt{ width: 200px; height: 30px; border: 1px solid #ccc;}</style></head><body><div class="box"> <input class="ipt"></div></body> </html>
【3】IE6-浏览器下当input元素被div包围时,在已经给input设置浮动的情况下,设置border:none无法得到理想效果
【解决】
[1]设置border:0
[2]重置input的背景
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}input{ margin: 0; padding: 0; border: none;}.box{ width: 201px; height: 31px; border: 1px solid black; background-color: red;}.ipt{ width: 200px; height: 30px; border: none; float: left;}</style></head><body><div class="box"> <input class="ipt"></div></body> </html>
【4】IE7-浏览器下输入类型表单控件如
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>body{ margin: 0;}.test{ overflow: auto; background: url(img/bg.jpg) no-repeat; font-size: 50px; line-height: 60px; height: 200px; width: 500px;}</style></head><body><textarea class="test"></textarea></body> </html>
【5】IE6-浏览器中select控件无法被
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Document</title><style>input{ width: 100px; height: 100px; background-color: lightgreen;}.box{ width: 200px; height: 200px; position: absolute; top: 20px; left: 20px; background-color: pink;}</style></head><body><select class="select"> <option>test1</option> <option>test2</option> <option>test3</option></select><div class="box" id="box"><iframe style="width:50px; height:50px;border: 0; position: absolute; opacity = 0; filter:alpha(opacity=0)"></iframe></div></body> </html>
