问题
I need to insert the content of a stylesheet into the <head> of an HTML page. How can I do it in Gulp?
Before (what I have):
<head>
<link href="style.css" rel="stylesheet" type="text/css" />
</head>
After (what I want):
<head>
<style>
p { color: pink; }
</style>
</head>
Note that I do not need to inline CSS into the elements, but just put the contents of CSS in the <head>.

You could easily use gulp-replace, like so:
var gulp = require('gulp'),
replace = require('gulp-replace'),
fs = require('fs');
// in your task
return gulp.src(...)
.pipe(replace(/<link href="style.css"[^>]*>/, function(s) {
var style = fs.readFileSync('style.css', 'utf8');
return '<style>\n' + style + '\n</style>';
}))
.pipe(gulp.dest(...));
You can also easily modify the replacement RegEx to work with different files, too.
return gulp.src(...)
.pipe(replace(/<link href="([^\.]\.css)"[^>]*>/g, function(s, filename) {
var style = fs.readFileSync(filename, 'utf8');
return '<style>\n' + style + '\n</style>';
}))
.pipe(gulp.dest(...));

You can inline the styles using import:
<style> @import "style.css"; </style>
