Creates a Modernizr config file that requires only the tests that your CSS uses.
$ npm install -g css2modernizrIf you haven't sufficient permissions may be you should use sudo
$ npm install --save css2modernizr$ css2modernizr /path/to/your/css/file.cssOr if you use Modernizr's prefixes in your css:
$ css2modernizr --prefix prfx- /path/to/your/css/file.cssWhere prfx- is part in class name .prfx-no-flexbox or .prfx-rgba
var css2modernizr = require('css2modernizr');
var result = css2modernizr(css, prefix).usage();Let's imagine we have the following CSS:
.block {
display: flex;
flex-flow: column nowrap;
position: absolute;
z-index: 20;
left: 50%;
margin: 15px 0 0 0;
padding: 20px 20px 15px;
background-color: rgba(255, 255, 255, 0.9);
box-shadow: 0 2px 10px rgba(0, 0, 0, 0.25);
backface-visibility: hidden;
transform: translate(-50%, 0);
visibility: hidden;
}
.no-boxshadow .block {
border: 1px solid #bfbfbf;
border-top: none;
margin-top: 14px;
}
.no-rgba .block {
background-color: white;
}
.no-csstransforms .block {
left: 0;
}
.no-flexbox .block {
display: block;
z-index: 10;
}
.block__element {
position: absolute;
top: -10px;
left: calc(50% - 10px);
display: block;
height: 0;
width: 0;
border-left: 10px solid transparent;
border-right: 10px solid transparent;
border-bottom: 10px solid white;
}
.no-csstransforms .block__element {
left: 0;
}If you run css2modernizr on this CSS, then result will be:
$ ./bin/css2modernizr test/example.css develop [2deb29d] modified untracked
No prefix (e.g. .no-flexbox, .rgba)
