jQuery implements a simple daily love elimination game_jquery

Today I share a small demo: "Tiantian Love Elimination Game". I think everyone is familiar with this game! ? A very popular mobile game recently

Miaowei’s lecturer also likes to play this game. In his spare time, he wrote a simple version of Love Elimination Every Day. In addition to the PC version, try playing it on iPad and iPhone~

Knowledge points involved: JS, HTML5;
