1、先定义common.scss全局引入文件
$vw_fontsize : 16;//默认初始值
$vw_design: 1920;//设计稿宽度
$min_width: 1200px;//最小宽度
@function rem($px) {
@if $px==0 {
@return 0;
}
@return calc($px / $vw_fontsize) * 1rem;
}
html {
font-size: calc($vw_fontsize / $vw_design) * 100vw;
@media screen and (max-width: 1200px) {// 最小宽度 最小值,不再变化
font-size: 10px;
}
}
body {
min-width: $min_width;
}
2、使用
width:rem(12)//12为设计稿的宽度;
font-size:rem(12)//12为设计稿的大小;
以下自定义common.scss文件
$vw_fontsize : 16;
$vw_design: 1920;
$min_width: 1200px;
@function rem($px) {
@if $px==0 {
@return 0;
}
@return calc($px / $vw_fontsize) * 1rem;
}
html {
font-size: calc($vw_fontsize / $vw_design) * 100vw;
@media screen and (max-width: 1200px) {
font-size: 10px;
}
