How to configure PostCSS/PurgeCSS with hugo to save classes for disabled elements?
html code example: ``
`postcss.config.js`:
```auto
const purgecss = require('@fullhuman/postcss-purgecss')({
content: ['./hugo_stats.json'],
defaultExtractor: (content) => {
let els = JSON.parse(content).htmlElements;
return els.tags.concat(els.classes, els.ids);
}
});
module.exports = {
plugins: [
...( [purgecss] )
]
};
```
`config.yaml`:
```auto
build:
# Used by PurgeCSS
writeStats: true
```
In my case all `[disabled]` classes (like `a[disabled]`) are removed after PurgeCSS.
How to fix it?

AFAIK, PurgeCSS allows you to define a white list of selectors for those elements that should not be removed. Something like `a[disabled]` might work.
In any case, you should check the documentation for PurgeCSS as this has nothing to do with Hugo per se.
