1、link和@import区别 https://www.cnblogs.com/my--sunshine/p/6872224.html
区别1:link是XHTML标签,除了加载CSS外,还可以定义RSS等其他事务;@import属于CSS范畴,只能加载CSS。
区别2:link引用CSS时,在页面载入时同时加载;@import需要页面完全载入以后加载。
区别3:link是XHTML标签,无兼容问题;@import是在CSS2.1提出的,低版本的浏览器不支持。
区别4:link支持使用Javascript控制DOM去改变样式;而@import不支持。
区别5: link引入的样式权重大于@import引入的样式。
2、通过swiper插件实现页面轮播效果(具体使用方法可以在官网查找) https://www.swiper.com.cn/
$npm install vue-awesome-swiper@版本号 --save
3、300ms点击延迟问题(移动端浏览器常见问题)——引入fastClick
$npm install fastClick --save
在main.js文件中引入fastClick:import FastClick from 'fastclick'
并添加 FastClick.attach(document.body);
4、移动端1像素边框问题(页面显示边框看上去超过1px)——引入border.css

}
}
5、height和line-height:
height指的是容器的高度
line-height指的是容器内每一行文字的高度
当同时设置的两个值并是两者相等会让文字在容器内垂直居中显示
6、路由配置实现路由跳转
在router文件下添加路径例如
routes: [{
path: '/',
name: 'home',
component: home
}
path所指向的就是跳转页面路径
并在需要设置页面跳转处添加 实现页面跳转
7、图片宽高比自适应(浏览器窗口尺寸改变时,图片的宽高比也不会改变)
width:100%
height:0
padding-bottom:图片宽度/图片高度*100%
overflow:hidden
8、网页宽度自动适应移动端屏幕宽度(IDE使用vscode自带)
9、diaplay:flex设置页面弹性布局
