解决CSS浏览器兼容性问题的一些方案浅析

由 蓝咒 提交于 2020-07-29 04:05:03
　　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

从0开始搭建vue+webpack脚手架（二）

接着 从0开始搭建vue+webpack脚手架（一） 三、配置webpack-dev-server 　　1. webpack-dev-server自带一个node的服务器， 项目在服务端运行的同时可以实现热更新加载 　　2. 安装兼容环境变量的包 cross-env 　　（1）原因： 构建项目时分生产环境和开发环境，此时webpack需要配置production和development模式，需要使用一个变量来作条件判断，而不同的平台上设置环境变量方式不同，在Mac平台是 NODE_ENV=production 而windows平台上是set NODE_ENV=production,，所以需要使用cross-env 　　（2）安装 1 $ npm i -D cross-env 　　（3）将package.json运行脚本改为如下： 1 "scripts" : { 2 "test": "echo \"Error: no test specified\" && exit 1" , 3 "build": "cross-env NODE_ENV=production webpack --progress --colors" , 4 "dev": "cross-env NODE_ENV=development webpack-dev-server --colors --modules -

Is there a way to test if PostCSS Autoprefixer is working? Specifically for Rails 6

由 ＊爱你＆永不变心＊ 提交于 2019-12-23 17:24:03
问题 I am writing a Rails 6 webapp using Webpacker. Its my understanding that auto-prefixing in Rails 6 works out of the box via PostCSS and its autoprefixer plugin. However I cannot verify if this library is in fact prefixing my css or not. Is there a way to confirm if a standard default Rails 6.0.0 app auto-prefixes out of the box? I have run yarn autoprefixer --info to see the css rules and browsers it applies to and its def applying to my browser chrome 77 . And I tried using a parameter that
