html动态心代码

HTML动态心代码已成为当前最火热的技术趋势之一。它是指在网页上实现心形图案并能够动态变换的代码技巧。

      {
        const container = document.querySelector('.container')
        const colors = ['#ffb6b9','#ff9aa2','#f6abb6','#f7accf','#c4bed4']
        const numHearts = 40
        const heartScaleFactor = 2
        const maxDegree = 360
        const hearTradius = 15
      
        function createHeart() {
          const heart = document.createElement('div')
          heart.classList.add('heart')
          heart.style.backgroundColor = colors[Math.floor(Math.random() * colors.length)]
          heart.style.width = hearTradius + 'px'
          heart.style.height = hearTradius + 'px'
          heart.style.position = 'absolute'
          heart.style.top = '50%'
          heart.style.left = '50%'
          container.appendChild(heart)
      
          return heart
        }
      
        function animateHeart(heart) {
          let positionX = heart.style.left
          let positionY = heart.style.top
          let degree = 0
          let animationDuration = Math.random() * 2 + 1
      
          setInterval(function() {
            const scale = Math.sin(degree / maxDegree * Math.PI) * heartScaleFactor
            heart.style.transform = `translate(${positionX},${positionY}) scale(${scale}) rotate(${degree}deg)`
            degree += 3
          },30)
        }
      
        function init() {
          const containerWidth = container.offsetWidth
          const containerHeight = container.offsetHeight
      
          for (let i = 0; i 

上述代码实现了在网页上生成一定数量的心形，每个心形的颜色随机，大小不断变化，并能够不停地旋转。这可以通过transform属性结合定时器实现。而底部的init()函数中则包含了每个心形的创建和位置、动画控制等关键代码。
