HTML5游戲特效是現(xiàn)在很流行的一種游戲類型，它基于HTML5技術，實現(xiàn)了很多高級特效功能，如音頻、視頻、3D圖形和動畫等。下面是一些HTML5游戲特效代碼示例：

//CSS代碼示例：
div#game {
position: relative;
width: 800px;
height: 600px;
background-color: #ccc;
}
div#player {
position: absolute;
left: 50%;
bottom: 0;
width: 50px;
height: 80px;
background: url(player.png) no-repeat center center;
transform: translateX(-50%);
}
//JavaScript代碼示例：
var canvas = document.getElementById('gameCanvas');
var context = canvas.getContext('2d');
context.strokeStyle = 'black';
context.fillStyle = 'red';
context.fillRect(10, 10, 50, 50);
context.strokeRect(10, 10, 50, 50);
context.beginPath();
context.moveTo(100, 100);
context.lineTo(200, 100);
context.stroke();
var player = {
x: 0,
y: canvas.height - 100,
width: 50,
height: 100,
color: 'blue',
move: function() {
this.x += 10;
},
draw: function() {
context.fillStyle = this.color;
context.fillRect(this.x, this.y, this.width, this.height);
}
};
