css-兼容性问题及解决(一)
1：在IE6下元素的高度的小于19px的时候，会被当做19px来处理
解决办法: overflow:hidden;
1 <!DOCTYPE HTML> 2 <html> 3 <head> 4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> 5 <title>无标题文档</title> 6 <style> 7 .box{height:2px;background:red;overflow:hidden;} 8 /* 9 IE6下最小高度问题10 在IE6下元素的高度的小于19px的时候，会被当做19px来处理11 解决办法:overflow:hidden;12 */13 </style>14 </head>15 <body>16 <div class="box"></div>17 </body>18 </html>
2： 1px dotted 在IE6下不支持
解决：切背景平铺
1 <!DOCTYPE HTML> 2 <html> 3 <head> 4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> 5 <title>无标题文档</title> 6 <style> 7 .box{ width:100px;height:100px;border:1px dotted #000;} 8 /* 9 1px dotted 在IE6下不支持10 解决办法:切背景平铺11 */12 </style>13 </head>14 <body>15 <div class="box"></div>16 </body>17 </html>
3： 在IE6下父级有边框的时候，子元素的margin值消失，在IE6下解决margin传递要触发haslayout
解决办法:触发父级的haslayout
<!DOCTYPE HTML><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><title>无标题文档</title><style>body{margin:0;}.box{background:blue;border:1px solid #000;zoom:1;}.div{width:200px;height:200px;background:red;margin:100px;}/* 在IE6下解决margin传递要触发haslayout 在IE6下父级有边框的时候，子元素的margin值消失 解决办法:触发父级的haslayout*/</style></head><body><div class="box"> <div class="div"></div></div></body></html> IE6下子元素margin值失效
触发haslayout
4：IE6下双边距BUG ，也就是说，在IE6下块元素有浮动和横向的margin值，横向的margin值会被放大成两倍
1 <!DOCTYPE HTML> 2 <html> 3 <head> 4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> 5 <title>无标题文档</title> 6 <style> 7 body{margin:0;} 8 .box{width:200px;height:200px;background:Red;float:left;margin:100px;display:inline;} 9 /*10 IE6下双边距BUG11 在IE6，块元素有浮动和和横向的margin值 ，横向的margin值会被放大成两倍12 解决办法: display:inline;13 */14 </style>15 </head>16 <body>17 <div class="box"></div>18 </body>19 </html> 5：在IE6，7下，li本身没浮动，但是li的内容有浮动，li下边就会产生一个4px间隙
解决办法:
1.给li加浮动，并且要加上宽度
2.给li加vertical-align
1 <!DOCTYPE HTML> 2 <html> 3 <head> 4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> 5 <title>无标题文档</title> 6 <style> 7 ul{margin:0;padding:0;width:302px;} 8 li{ list-style:none;height:30px;border:1px solid #000;vertical-align:top; } 9 a{width:100px;float:left;height:30px;background:Red;}10 span{width:100px;float:right;height:30px;background:blue;}11 /*12 在IE6，7下，li本身没浮动，但是li的内容有浮动，li下边就会产生一个间隙13 解决办法:14 1.给li加浮动 ，并且要加上宽度15 2.给li加vertical-align16 */17 </style>18 </head>19 <body>20 <ul>21 <li>22 <a href="#"></a>23 <span></span>24 </li>25 <li>26 <a href="#"></a>27 <span></span>28 </li>29 <li>30 <a href="#"></a>31 <span></span>32 </li>33 </ul>34 </body>35 </html>
ie6,7下
<strong>vertical-align:top</strong>
6：在IE6，7下，li本身没浮动，但是li的内容有浮动，li下边就会产生一个4px间隙,如果和最小高都问题并存的时候，也要个li加浮动
1 <!DOCTYPE HTML> 2 <html> 3 <head> 4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> 5 <title>无标题文档</title> 6 <style> 7 ul{margin:0;padding:0;width:302px;} 8 li{ list-style:none;height:12px;border:1px solid #000;overflow:hidden; float:left;width:300px;} 9 9 a{width:100px;float:left;height:12px;background:Red;}10 span{width:100px;float:right;height:12px;background:blue;}11 /*12 在IE6，7下，li本身没浮动，但是li的内容有浮动，li下边就会产生一个间隙13 解决办法:14 1.给li加浮动并且要加上宽度15 2.给li加vertical-align16 17 当IE6下最小高度问题，和 li的间隙问题共存的时候 给li加浮动18 */19 </style>20 </head>21 <body>22 <ul>23 <li>24 <a href="#"></a>25 <span></span>26 </li>27 <li>28 <a href="#"></a>29 <span></span>30 </li>31 <li>32 <a href="#"></a>33 <span></span>34 </li>35 </ul>36 </body>37 </html>
7：当一行子元素占有的宽度之和和父级的宽度相差超过3px,或者有不满行状态的时候,最后一行子元素的下margin在IE6下就会失效
解决办法:精确计算父级和子元素的宽度
或者有不满行状态的时候,最后一行子元素的下margin在IE6下就会失效
1 <!DOCTYPE HTML> 2 <html> 3 <head> 4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> 5 <title>无标题文档</title> 6 <style> 7 .box{border:10px solid #000;width:600px; overflow:hidden;} //清浮动 8 .box div{width:100px;height:100px;background:Red;margin:20px;border:5px solid #ccc; float:left; 9 display:inline;} //双边距bug10 /* 11 不满行状态的时候,最后一行子元素的下margin在IE6下就会失效12 */13 </style>14 </head>15 <body>16 <div class="box">17 <div>1</div>18 <div>2</div>19 <div>3</div>20 <div>4</div>21 <div>1</div>22 <div>2</div>23 <div>3</div>24 <div>4</div>25 <div>1</div>26 <div>2</div>27 <div>3</div>28 </div>29 </body>30 </html><br />
当一行子元素占有的宽度之和和父级的宽度相差超过3px,最后一行子元素的下margin在IE6下就会失效
1 <!DOCTYPE HTML> 2 <html> 3 <head> 4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> 5 <title>无标题文档</title> 6 <style> 7 .box{border:10px solid #000;width:604px; overflow:hidden;} //清浮动 8 .box div{width:100px;height:100px;background:Red;margin:20px;border:5px solid #ccc; float:left; 9 display:inline;} //双边距bug10 /*11 当一行子元素占有的宽度之和和父级的宽度相差超过3px,最后一行子元素的下margin在IE6下就会失效12 */13 </style>14 </head>15 <body>16 <div class="box">17 <div>1</div>18 <div>2</div>19 <div>3</div>20 <div>4</div>21 <div>1</div>22 <div>2</div>23 <div>3</div>24 <div>4</div>25 <div>1</div>26 <div>2</div>27 <div>3</div>28 <div>4</div>29 </div>30 </body>31 </html>
