Question

I’m working with a CMS that prevents us from editing the head section. I need to add css stylesheet to the site, right after the tag. Is there a way to do this with JS, where I can add a script to the bottom of the page (I have access to add script right before the tag) that would then inject the stylesheet into the head section?

Answer 1

Update: According to specs, the link element is not allowed in the body. However, most browsers will still render it just fine. So, to answer the questions in the comments – one really has to add link to the head of the page and not the body.

function addCss(fileName) {

  var head = document.head;
  var link = document.createElement("link");

  link.type = "text/css";
  link.rel = "stylesheet";
  link.href = fileName;

  head.appendChild(link);
}

addCss('{my-url}');

Or a little bit easier with jquery

function addCss(fileName) {
   var link = $("<link />",{
     rel: "stylesheet",
     type: "text/css",
     href: fileName
   })
   $('head').append(link);
}

addCss("{my-url}");

Original answer:

You don’t need necessarily add it to the head, just add it to the end of body tag.

$('body').append('<link rel="stylesheet" type="text/css" href="{url}">')

as Juan Mendes mentioned, you can insert stylesheet to the head instead

$('head').append('<link rel="stylesheet" type="text/css" href="{url}">')

And the same without jQuery (see code above)
