Uncss for Bootstrap?

Question

css

I have concerns that uncss will cut out additional bootstrap styles that it will need for animations, modals, etc. Are my fears correct?
If you can, tell or show, please, how you have uncss configured in Galp)

Answer 1

Do it with styling CSS.

Answer 2

Yes, cut. You figure out what classes will be needed and create a hidden element in the footer to which you assign them.

Answer 3

for Bootstrap 3 this option was:

.pipe(uncss({
        html: ["dev/index.html", "prod/index.html"],
        ignore: [/\w\.in/,
                ".fade",
                ".collapse",
                ".collapsing",
                /(#|\.)navbar(\-[a-zA-Z]+)?/,
                /(#|\.)dropdown(\-[a-zA-Z]+)?/,
                /(#|\.)(open)/,
                ".modal",
                ".modal.fade.in",
                ".modal-dialog",
                ".modal-document",
                ".modal-scrollbar-measure",
                ".modal-backdrop.fade",
                ".modal-backdrop.in",
                ".modal.fade.modal-dialog",
                ".modal.in.modal-dialog",
                ".modal-open",
                ".in",
                ".modal-backdrop"]
    }))
