今天我要分享一个浪漫小技巧，使用Python中的HTML制作一个立体、动态的小爱心。通过成千上百个小爱心的组合，形成一个大爱心，从内到外呈现出立体的效果，给人带来强烈的视觉冲击。这个小技巧非常浪漫，让人感受到爱的力量。

一．粉色爱心

</style> <body>  <div id="jsi-cherry-container" class="container"> <audio autoplay="autopaly"> <source src="renxi.mp3" type="audio/mp3" /> </audio> <img class="img" src="./123.png" alt="" />  <canvas id="pinkboard" class="container"> </canvas> </div>

(function () { var b = 0; var c = ["ms", "moz", "webkit", "o"]; for (var a = 0; a < c.length && !window.requestAnimationFrame; ++a) { window.requestAnimationFrame = window[c[a] + "RequestAnimationFrame"]; window.cancelAnimationFrame = window[c[a] + "CancelAnimationFrame"] || window[c[a] + "CancelRequestAnimationFrame"]; } if (!window.requestAnimationFrame) { window.requestAnimationFrame = function (h, e) { var d = new Date().getTime(); var f = Math.max(0, 16 - (d - b)); var g = window.setTimeout(function () { h(d + f); }, f); b = d + f; return g; }; } if (!window.cancelAnimationFrame) { window.cancelAnimationFrame = function (d) { clearTimeout(d); }; } })(); /* *Point class */ var Point = (function () { function Point(x, y) { this.x = typeof x !== "undefined" ? x : 0; this.y = typeof y !== "undefined" ? y : 0; } Point.prototype.clone = function () { return new Point(this.x, this.y); }; Point.prototype.length = function (length) { if (typeof length == "undefined") return Math.sqrt(this.x * this.x + this.y * this.y); this.normalize(); this.x *= length; this.y *= length; return this; }; Point.prototype.normalize = function () { var length = this.length(); this.x /= length; this.y /= length; return this; }; return Point; })(); /* * Particle class */ var Particle = (function () { function Particle() { this.position = new Point(); this.velocity = new Point(); this.acceleration = new Point(); this.age = 0; } Particle.prototype.initialize = function (x, y, dx, dy) { this.position.x = x; this.position.y = y; this.velocity.x = dx; this.velocity.y = dy; this.acceleration.x = dx * settings.particles.effect; this.acceleration.y = dy * settings.particles.effect; this.age = 0; }; Particle.prototype.update = function (deltaTime) { this.position.x += this.velocity.x * deltaTime; this.position.y += this.velocity.y * deltaTime; this.velocity.x += this.acceleration.x * deltaTime; this.velocity.y += this.acceleration.y * deltaTime; this.age += deltaTime; }; Particle.prototype.draw = function (context, image) { function ease(t) { return --t * t * t + 1; } var size = image.width * ease(this.age / settings.particles.duration); context.globalAlpha = 1 - this.age / settings.particles.duration; context.drawImage( image, this.position.x - size / 2, this.position.y - size / 2, size, size ); }; return Particle; })();

运行结果：

二．蓝色动态爱心

表白界面

下边是表白运行代码：

def OK(): #同意按钮 root.destroy() love() #同意后显示漂浮爱心def NO(): #拒绝按钮，拒绝不会退出，必须同意才可以退出哦~ tk.messagebox.showwarning('❤','再给你一次机会！')def closeWindow(): tk.messagebox.showwarning('❤','逃避是没有用的哦')————————————————版权声明：本文为CSDN博主「Want595」的原创文章，遵循CC 4.0 BY-SA版权协议，转载请附上原文出处链接及本声明。
