浏览器hack总结 详细的浏览器兼容性解决方法
由于各浏览器对页面的解析不同，会导致页面在不同浏览器中显示的样式不一致，为了保持页面的统一，经常需要对浏览器进行兼容性问题的调试。
CSS Hack
面对浏览器诸多的兼容性问题，经常需要通过CSS样式来调试，其中用的最多的就是CSS Hack。所谓CSS Hack就是针对不同的浏览器书写不同的CSS样式，通过使用某个浏览器单独识别的样式代码，控制该浏览器的显示效果。CSS Hack主要分为两类
CSS 选择器Hack
CSS选择器Hack是指通过在CSS选择器的前面，加上一些只有特定浏览器才能识别的Hack前缀，来控制不同的CSS样式。针对不同版本的浏览器，选择器Hack分为以下几类：
（1）IE6及IE6以下版本识别的选择器Hack
书写CSS样式时，如果希望此样式只对IE6及IE6以下版本的浏览器生效，可以使用IE6及以下版本的选择器Hack，其基本语法如下：
* html 选择器{样式代码}
（2）IE7识别的选择器Hack
书写CSS样式时，如果希望此样式只对IE7浏览器生效，可以使用IE7识别的选择器Hack，其基本语法如下：
*+html 选择器{样式代码}
CSS属性Hack
这里小强老师，把属性hack分为 前缀属性hack和 后缀属性hack
| CSS属性Hack（前缀） | 针对的浏览器 |
| _color:red; | IE6及其以下的版本 |
| *color:red ;或者 +color:red; | IE7及其以下的版本 |
| CSS属性Hack（后缀） | 针对的浏览器 |
| color:red\9; | IE6/IE7/IE8/IE9/IE10版本 |
| color:red\0; | IE8/IE9/IE10版本 |
| color:red\9\0; | IE9/IE10 |
| color:red!important | IE7/IE8/IE9/IE10及其他非IE浏览器 |
其实，现在越来越的公司，不太让兼容ie6了，现在比较关心的是ie8.910等高版本的浏览器，因此这里小强老师也总结了ie专属hack ，比如ie8等。
| 选择器Hack写法 | 针对于的浏览器 |
| @media screen\9{body { background: red; }} | 只对IE6/7生效 |
| @media \0screen {body { background: red; }} | 只对IE8生效 |
| @media \0screen\,screen\9{body { background: blue; }} | 只对IE6/7/8有效 |
| @media screen\0 {body { background: green; }} | 只对IE8/9/10有效 |
| @media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {body { background: orange; }} | 只对IE10有效 |
如果样式比较多，条件注释，是不错的选择：
IE条件注释语句
| IE条件注释语句 | 针对的浏览器版本 |
| IE7 以下版本 | |
| IE7及以下版本（包含IE7） | |
| IE7 以上版本 | |
| IE7及以上版本（包含IE7） | |
| 非IE7版本 | |
| 您使用不是 Internet Explorer | 非IE浏览器 |

HTML semantics improve accessibility and SEO effects, and Web components improve development efficiency, but attention should be paid to browser compatibility. 2. CSS-in-JS enhances style management flexibility but may increase file size. CSSHoudini allows direct operation of CSS rendering. 3.WebAssembly optimizes browser application performance but has a steep learning curve, and Serverless simplifies development but requires optimization of cold start problems.
