// @name TestAlert
// @description Alert
// @author Userscripts
// @version 0.0.1
// @match *://*/*
// @grant none
// @inject-into content
// ==/UserScript==
(function () {
alert("This is a test script");
})();
TestHideCss.js Code:
// ==UserScript==
// @name TestHideCss
// @description Test CSS
// @version 0.0.1
// @author getoutnow
// @match *://*/*
// @grant GM_addStyle

(function () {
const myStyleCss = `body.readable { display:none !important; }`;
document.body.className += 'readable';
GM_addStyle(myStyleCss);
})();
