移动端项目开发配置

一 、移动端开发要配置meta

 <!-- 移动端开发要先配置meta -->
    <!-- minimum-scale=1.0,maximum-scale=1.0,user-scalable=no 这样的话用户通过手指放大缩小是没用的页面的比例始终是1比1 -->
    <meta name="viewport" content="width=device-width,initial-scale=1.0,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no">

二、配置reset.css文件

重置页面的样式表，也就是说在不同型号的手机上默认样式是不同的，我们需要把不同手机的初始化样式做一个统一，所以我们要引入一个reset.css文件

@charset "utf-8";
html {
    
    
    background-color: #fff;
    color: #000;
    font-size: 12px;

}
 
html {
    
    
    overflow-x: hidden;
    height: 100%;
    font-size: 50px;
    -webkit-tap-highlight-color: transparent;
}
 
body {
    
    
    font-family: Arial, "Microsoft Yahei", "Helvetica Neue", Helvetica, sans-serif;
    color: #333;
    font-size: .28em;
    line-height: 1;
    -webkit-text-size-adjust: none;
}
 
hr {
    
    
    height: .02rem;
    margin: .1rem 0;
    border: medium none;
    border-top: .02rem solid #cacaca;
}
 
a {
    
    
    color: #25a4bb;
    text-decoration: none;
}

三、配置border.css

该css样式用于解决移动端1像素边框问题。问题分析：有些手机的屏幕分辨率较高，是2-3倍屏幕。css样式中border:1px solid red;在2倍屏下，显示的并不是1个物理像素，而是2个物理像素。为了解决这个问题，引入border.css是非常有必要的。

}

四、解决移动端300毫秒点击延迟

在移动端的某些机型上、某些浏览器上当你使用click事件的时候，这个click回延迟300毫秒然后才执行

// 在终端
npm install fastclick --save
// 把fastclick这个包安装到我项目的依赖中 --save的意思是不管我们在开发环境中还是线上版本的代码都需要使用fastclick
// 这个时候我们就要用--save 把fastclick存到package.json中的devDependencies中

//在main.js中引入fastclick
import fastClick from 'fastclick'
// 使用fastclick   attach 是fastclick自带的一个方法 把他绑定到document.body上
fastClick.attach(document.body)

五、iconfont

新建项目图标库，把需要的图标添加到项目中并下载

把字体文件都放进iconfont中
iconfont.css放到styles中
打开iconfont.css 由于引入的不在当前路径所以要修改路径 改为：
./iconfont/iconfont.eot?t=1611649847296

// 使用 在main.js中引入iconfont （因为基本上每个页面都需要引入iconfont）
import './assets/styles/iconfont.css'
// 使用
<span class="iconfont">&#xe624;</span>

六、初始化完成

• 清理没有必要的代码
• 上传

git add . // 把本地的修改提交到本地git的缓冲区
git commit -m 'project init' // 把本地缓冲区的内容提交到本地的仓库 
git push
