javascript - Automatically embed a stylesheet in HTML -


i'm building out error pages (404/503) need standalone html files, server-side nodejs, these files hosted directly in nginx. i'm trying automatically embed stylesheet @ top of html document , wondering whether there tools purpose. searching on stack overflow , google keeps returning tools inline css use in emails, not want.

i start out with

before.css

.body { color: black }

before.html

<!doctype html> <html>   <head>     <title>a question</title>     <link rel="stylesheet" href="before.css">   </head>   <body>     <p>here answer</p>   </body> </html>

which once process complete end with

after.html

<!doctype html> <html>   <head>     <title>a question</title>     <style>.body { color: black }</style>   </head>   <body>     <p>here answer</p>   </body> </html>

the ideal solution gulp plugin or idea of how write one.
can write in js if needed. i'm using ejs , stylus derive original before files.

many thanks

as many commented, you're trying find solution complex problem , there many easy use workarounds this. if want here few approaches think best:

server-side templates:

the best, clean , straightforward method of embedding stylesheet html use server-side scripting language (as @mr_green pointed out). there many chose from, , you're using node.js, best library ejs or jade. can use php, ruby, python or whatever think best, idea same:

  1. first, need read contents stylesheet , store in variable. in node.js can use fs.readfile() read contents of .css file.
  2. then, have output contents of .css file (stored in variable) html. ejs example, if contents of css file in variable stylefile, can <style><%= stylefile %></style> directly put contents of stylesheet html <style> tag.

using ajax javascript:

another solution use ajax , contents of stylesheet , use javascript put inside <style> tag. example jquery do: $("style").html(// stylesheet contents var);.

of course can use haml, if helps.

hope answers question.
