在不同的浏览器中,HTML标签会有一些默认的属性值,但是各个浏览器会渲染出各不一样的效果,例如边距不一致、字体颜色大小行高不一样等等,为了防止出现这种情况,其实主要是为了减少代码的重复定义,提高代码复用率,提高开发效率,重设各个浏览器的默认样式,还可以解决其引起的耦合问题
代码:
/* 指定css文件编码为utf-8 */
@charset "utf-8"
* {
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}
*:before,
*:after {
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}
body, div, dl, dt, dd, ul, ol, li, h1, h2, h3, h4, h5, h6, pre, code, form, fieldset, legend, input, button, textarea, p, blockquote, th, td {
margin: 0;
padding: 0;
}
body {
background: #fff;
color: #555;
font-size: 14px;
font-family: "Arial", "Microsoft YaHei", "黑体", "宋体", sans-serif;
}
td, th, caption {
font-size: 14px;
}
h1, h2, h3, h4, h5, h6 {
font-weight: normal;
font-size: 100%;
}
address, caption, cite, code, dfn, em, strong, th, var {
font-style: normal;
font-weight: normal;
}
a {
color: #555;
text-decoration: none;
}
a:hover {
text-decoration: underline;
}
img {
border: none;
vertical-align: middle;
}
ol, ul, li {
list-style: none;
}
input, textarea, select, button {
font: 14px "Arial", "Microsoft YaHei", "黑体", "宋体", sans-serif;
}
table {
border-collapse: collapse;
}
html {
overflow-y: scroll;
}
.clearfix:before,
.clearfix:after {
content: " ";
display: inline-block;
height: 0;
clear: both;
visibility: hidden;
}
.clearfix {
*zoom: 1;
}
/*公共类*/
.fl {
float: left
}
.fr {
float: right
}
.al {
text-align: left
}
.ac {
text-align: center
}
.ar {
text-align: right
}
.hide {
display: none
}
使用:
在main.js文件中引入:
import "@/assets/styles/reset.css"
使用重置文件的优点就是高复用、低耦合、体积小。
