Advanced tools
A CSS post-processor that converts px to viewport units (vw, vh, vmin, vmax).
English | 中文
将px单位转换为视口单位的 (vw, vh, vmin, vmax) 的 PostCSS 插件.
如果你的样式需要做根据视口大小来调整宽度,这个脚本可以将你CSS中的px单位转化为vw,1vw等于1/100视口宽度。
.class {
margin: -10px .5vh;
padding: 5vmin 9.5px 1px;
border: 3px solid black;
border-bottom-width: 1px;
font-size: 14px;
line-height: 20px;
}
.class2 {
padding-top: 10px; /* px-to-viewport-ignore */
/* px-to-viewport-ignore-next */
padding-bottom: 10px;
/* Any other comment */
border: 1px solid black;
margin-bottom: 1px;
font-size: 20px;
line-height: 30px;
}
@media (min-width: 750px) {
.class3 {
font-size: 16px;
line-height: 22px;
}
}
.class {
margin: -3.125vw .5vh;
padding: 5vmin 2.96875vw 1px;
border: 0.9375vw solid black;
border-bottom-width: 1px;
font-size: 4.375vw;
line-height: 6.25vw;
}
.class2 {
padding-top: 10px;
padding-bottom: 10px;
/* Any other comment */
border: 1px solid black;
margin-bottom: 1px;
font-size: 6.25vw;
line-height: 9.375vw;
}
@media (min-width: 750px) {
.class3 {
font-size: 16px;
line-height: 22px;
}
}
使用npm安装
$ npm install postcss-px2vwpro --save-dev
或者使用yarn进行安装
$ yarn add -D postcss-px2vwpro
默认参数:
{
unitToConvert: 'px',
viewportWidth: 320,
unitPrecision: 5,
propList: ['*'],
viewportUnit: 'vw',
fontViewportUnit: 'vw',
selectorBlackList: [],
minPixelValue: 1,
mediaQuery: false,
replace: true,
exclude: undefined,
include: undefined,
landscape: false,
landscapeUnit: 'vw',
landscapeWidth: 568
}
unitToConvert
(String) 需要转换的单位,默认为"px"viewportWidth
(Number) 设计稿的视口宽度unitPrecision
(Number) 单位转换后保留的精度propList
(Array) 能转化为vw的属性列表
viewportUnit
(String) 希望使用的视口单位fontViewportUnit
(String) 字体使用的视口单位selectorBlackList
(Array) 需要忽略的CSS选择器,不会转为视口单位,使用原有的px等单位。
selectorBlackList
为 ['body']
的话, 那么 .body-class
就会被忽略selectorBlackList
为 [/^body$/]
, 那么 body
会被忽略,而 .body
不会minPixelValue
(Number) 设置最小的转换数值,如果为1的话,只有大于1的值会被转换mediaQuery
(Boolean) 媒体查询里的单位是否需要转换单位replace
(Boolean) 是否直接更换属性值,而不添加备用属性exclude
(Array or Regexp) 忽略某些文件夹下的文件或特定文件,例如 'node_modules' 下的文件
include
(Array or Regexp) 如果设置了include
,那将只有匹配到的文件才会被转换,例如只转换 'src/mobile' 下的文件
(include: /\/src\/mobile\//
)
landscape
(Boolean) 是否添加根据 landscapeWidth
生成的媒体查询条件 @media (orientation: landscape)
landscapeUnit
(String) 横屏时使用的单位landscapeWidth
(Number) 横屏时使用的视口宽度
exclude
和include
是可以一起设置的,将取两者规则的交集。
You can use special comments for ignore conversion of single lines:
/* px-to-viewport-ignore-next */
— on a separate line, prevents conversion on the next line./* px-to-viewport-ignore */
— after the property on the right, prevents conversion on the same line.Example:
/* example input: */
.class {
/* px-to-viewport-ignore-next */
width: 10px;
padding: 10px;
height: 10px; /* px-to-viewport-ignore */
border: solid 2px #000; /* px-to-viewport-ignore */
}
/* example output: */
.class {
width: 10px;
padding: 3.125vw;
height: 10px;
border: solid 2px #000;
}
There are several more reasons why your pixels may not convert, the following options may affect this:
propList
, selectorBlackList
, minPixelValue
, mediaQuery
, exclude
, include
.
在postcss.config.js
添加如下配置
module.exports = {
plugins: {
// ...
'postcss-px2vwpro': {
// options
}
}
}
viewportWidth
as function
module.exports = {
plugins: {
// ...
'postcss-px2vwpro': {
// options
viewportWidth({ file }) {
return file.indexOf('vant') !== -1 ? 375 : 750
},
}
}
}
在 gulpfile.js
添加如下配置:
var gulp = require('gulp');
var postcss = require('gulp-postcss');
var pxtoviewport = require('postcss-px2vwpro');
gulp.task('css', function () {
var processors = [
pxtoviewport({
viewportWidth: 320,
viewportUnit: 'vmin'
})
];
return gulp.src(['build/css/**/*.css'])
.pipe(postcss(processors))
.pipe(gulp.dest('build/css'));
});
为了跑测试案例,您需要安装开发套件:
$ npm install
然后输入下面的命令:
$ npm run test
