Whitelisting
You can whitelist selectors to stop PurgeCSS from removing them from your CSS. This can be accomplished with the PurgeCSS options
whitelist and whitelistPatterns, or directly in your CSS with a special comment.You can whitelist selectors with
whitelist.const purgecss = new Purgecss({
content: [], // content
css: [], // css
whitelist: ['random', 'yep', 'button']
})
In the example, the selectors
.random, #yep, button will be left in the final CSS.You can whitelist selectors based on a regular expression with
whitelistPatterns and whitelistPatternsChildren.const purgecss = new Purgecss({
content: [], // content
css: [], // css
whitelistPatterns: [/red$/],
whitelistPatternsChildren: [/blue$/]
})
In the example, selectors ending with
red such as .bg-red, and children of selectors ending with blue such as blue p or .bg-blue .child-of-bg, will be left in the final CSS.Patterns are regular expressions. You can use regexr to verify the regular expressions correspond to what you are looking for.
You can whitelist directly in your CSS with a special comment. Use
/* purgecss ignore */ to whitelist the next rule./* purgecss ignore */
h1 {
color: blue;
}
Use
/* purgecss ignore current */ to whitelist the current rule.h1 {
/* purgecss ignore current */
color: blue;
}
You can use
/* purgecss start ignore */ and /* purgecss end ignore */ to whitelist a range of rules./* purgecss start ignore */
h1 {
color: blue;
}
h3 {
color: green;
}
/* purgecss end ignore */
h4 {
color: purple;
}
/* purgecss start ignore */
h5 {
color: pink;
}
h6 {
color: lightcoral;
}
/* purgecss end ignore */
