現在什么都講究追趕潮流，覺得 QQ 登錄窗口做的效果不錯，既然剛學習 electron ，那么就用 electron 模仿一下。其實主要用到的就是 CSS3 的效果：邊框圓角、陰影，3D變換。對，就這么簡單。先上效果：
下面是關鍵代碼：
app.js
'use strict';const { app, BrowserWindow } = require('electron')const path = require('path')const url = require('url')// Keep a global reference of the window object, if you don't, the window will// be closed automatically when the JavaScript object is garbage collected.let winfunction createWindow() { // Create the browser window. win = new BrowserWindow({ width: 495, height: 470, /*skipTaskbar: true,*/ frame: false, resizable: false, transparent: true, show: false, alwaysOnTop: true }) win.once('ready-to-show', () => { win.show() }) // and load the index.html of the app. win.loadURL(url.format({ pathname: path.join(__dirname, '/app/index.html'), protocol: 'file:', slashes: true })) // Open the DevTools. //win.webContents.openDevTools() // Emitted when the window is closed. win.on('closed', () => { // Dereference the window object, usually you would store windows // in an array if your app supports multi windows, this is the time // when you should delete the corresponding element. win = null })}//app.disableHardwareAcceleration();// This method will be called when Electron has finished// initialization and is ready to create browser windows.// Some APIs can only be used after this event occurs.app.on('ready', createWindow)// Quit when all windows are closed.app.on('window-all-closed', () => { // On macOS it is common for applications and their menu bar // to stay active until the user quits explicitly with Cmd + Q if (process.platform !== 'darwin') { app.quit() }})app.on('activate', () => { // On macOS it's common to re-create a window in the app when the // dock icon is clicked and there are no other windows open. if (win === null) { createWindow() }})// In this file you can include the rest of your app's specific main process// code. You can also put them in separate files and require them here.index.html

總結
以上所述是小編給大家介紹的使用 electron 實現類似新版 QQ 的登錄界面效果(陰影、背景動畫、窗體3D翻轉)，希望對大家有所幫助，如果大家有任何疑問請給我留言，小編會及時回復大家的。在此也非常感謝大家對武林網網站的支持！
