解决CSS浏览器兼容性问题的一些方案浅析

阅读更多关于解决CSS浏览器兼容性问题的一些方案浅析

　　前端是一个苦逼的职业，不仅因为技术更新快，而且要会的东西实在太多了，更让人头疼的是，还要面临各种适配、兼容性问题。　　为什么会有浏览器兼容性问题。还不是因为浏览器厂商太多了。关键是不同厂商，甚至同一厂商不同版本，对同一段CSS的解析效果也不一致，这就导致了页面显示效果不统一，也就带来了兼容性问题。　　市场上浏览器种类很多，不同浏览器的内核也不尽相同，所以各个浏览器对网页的解析存在一定的差异。　　浏览器内核主要分为两种，一是渲染引擎，另一个是js 引擎，内核更加倾向于说渲染引擎。常见的浏览器内核可以分四种：Trident、Gecko、Blink、Webkit 　　我们暂且不去关注太多细节问题，比如那个css样式需要我们去兼容，而是想讨论一下大的解决思路，主要包括4个方面，浏览器CSS样式初始化、浏览器私有属性，CSS hack语法和自动化插件。 1、浏览器CSS样式初始化　　由于每个浏览器的css默认样式不尽相同，所以最简单有效的方式就是对其进行初始化，相信很多朋友都写过这样的代码，在所有CSS开始前，先把marin和padding都设为0，以防不同浏览器的显示效果不一样。以及对一些常用的html元素进行一些初始化处理等等。 * { margin: 0 ; padding: 0 ; } 　　关于浏览器CSS样式初始化，经验不丰富的话，可能也不知道该初始化什么
