Simpan kode CSS di folder xampplite – htdocs – buat folder baru dengan nama MatchColors– simpan code CSS dengan nama style.css.

5. Reload alamat url : http://localhost/MatchColors. Tampilan awal game match the colors, namun warna dalam game belum muncul.

6. Untuk menampilkan warna dalam game, buka kembali text editor dan ketikkan kode JavaScript berikut.

const computerCircle = document.querySelector(".computer-circle");
const userCircle = document.querySelector(".user-circle");
const btnMatch = document.getElementById("btn-match");

const red = document.getElementById("red");

Simpan kode JavaScript di folder xampplite – htdocs – buat folder baru dengan nama MatchColors– simpan code JavaScript dengan nama main.js.

7. Reload alamat url : http://localhost/MatchColors. Tampilan awal game match the color. Atur nilai red, green, dan blue untuk mendapatkan warna yang sesuai. Klik tombol match untuk melihat selisih perbedaan warna. Klik cheat untuk mengetahui nilai red, green dan blue. Klik ikon refresh untuk mendapatkan permainan baru.
