This is just a shim to add back in GM_addStyle for scripts in @grant none mode, or that run on benighted engines without native GM_addStyle support.
此腳本不應該直接安裝,它是一個供其他腳本使用的函式庫。欲使用本函式庫,請在腳本 metadata 寫上: // @require https://update.cn-greasyfork.org/scripts/44560/271595/GM_addStyle_shim.js
function GM_addStyle (cssStr) {
var D = document;
var newNode = D.createElement ('style');
newNode.textContent = cssStr;
var targ = D.getElementsByTagName ('head')[0] || D.body || D.documentElement;
targ.appendChild (newNode);
}
