Description
Incorrect value in font rule leads to an error which really hard to find.
I'm using clean-css as part of Angular Cli project, and I had to debug it manually to find what part of css cause this error.
Environment
- clean-css version - 4.1.9:
- node.js version - v9.6.1:
- operating system: Windows x64
Configuration options
const cleancss = new CleanCSS({
compatibility: 'ie9',
level: 2,
inline: false,
returnPromise: true,
});Input CSS
div {
font: normal;
}Actual output
c:\projects\meteoguard\node_modules\clean-css\lib\optimizer\level-2\properties\populate-components.js:32
throw e;
