如何使用 JavaScript 將樣式表動態新增到 Head？

Adding Stylesheets Dynamically to the Head Using JavaScript

Many Content Management Systems (CMSs) restrict access to the head section, making it challenging to incorporate additional stylesheets. However, a clever solution using JavaScript can effectively tackle this issue.

To inject stylesheets into the head section after the tag, we can leverage JavaScript's ability to manipulate the Document Object Model (DOM). The following code snippet demonstrates this technique:

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);
}

For a simpler solution using jQuery, consider the following:

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

Note: Recent specifications prohibit the use of the element in the tag. However, most browsers still render it correctly. Therefore, adding the stylesheet to the tag is technically feasible, although adhering to specifications dictates placing it in the tag instead.
