What is the equilvent of GM_addStyle in GM4?

[Xing]

Dear all,

I noticed that GM_addStyle is removed in GM4. However it is an crucial function in my script and I want to keep it compatible with Tampermonkey as well. Is there a new method to do similar things in GM4?

Thanks and best wishes,
Xing

I have the same problem. GM_addStyle() is crucial. Use these workarounds which found from stackoverflow:

function GM_addStyle_from_file(fileName) {
  var head = document.head
    , link = document.createElement("link")
  link.type = "text/css"
  link.rel = "stylesheet"
  link.href = fileName
  head.appendChild(link)
}

function GM_addStyle_from_string(str) {
    var node = document.createElement('style');
    node.innerHTML = str;
    document.body.appendChild(node);
}

Example usage:
GM_addStyle_from_file("https://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery.ui.base.css");

GM_addStyle_from_string (
    ".embeddedImgContainer {" +
        "background: "+imgContainerBackgroundColor+";" +
    "}" +
    ".embeddedImgAnchor {"+
        "display: inline-block;"+
    "}"
)

Use the GM polyfill: https://github.com/greasemonkey/gm4-polyfill
