今天寫點css3，3d屬性寫的3d盒子，結合javascript讓盒子隨滑鼠旋轉起來
今天帶了css3新屬性3d<!DOCTYPE html><html><head><meta charset="UTF-8"><title></title><style type="text/css">#a{width: 200px;height: 200px;margin: 200px auto;position:relative; /*給父元素相對定位*/transform-style: preserve-3d; /*父元素設為3d*/ transform: perspective(1000px) rotateY(30deg) rotateX(30deg); /*設定父元素得景深*/}#a>div{position:absolute;/*盒子每面的預設樣式*/width: 200px;height: 200px;border: 1px solid #000000;text-align: center;line-height: 200px;}#a>div:nth-child(1){transform: translateZ(100px);/*前面盒子寬為200px所以先向前位移100px*/background: rgba(0,0,255,0.2);}#a>div:nth-child(2){transform: translateZ(-100px);/*第二元素向後位移100px 這樣盒子前後面就有了*/background: rgba(0,255,0,0.2);}#a>div:nth-child(3){transform: rotateX(90deg) translateZ(100px);/*第三個讓他平躺下，也就是x軸旋轉90°，旋轉後在位移，這樣就會向他面對的那面去位移*/background: rgba(255,0,0,0.2);}#a>div:nth-child(4){transform: rotateX(90deg) translateZ(-100px);background: rgba(255,255,0,0.2);}#a>div:nth-child(5){transform: rotateY(90deg) translateZ(-100px);background: rgba(0,255,255,0.2);}/ /*總結就是先旋轉在位移，z軸就是div面向那面那面將會是z所以說先旋轉在位移這樣位移也就是100px 和 -100px 的事*/#a>div:nth-child(6){transform: rotateY(90deg) translateZ(100px);background: rgba();}</style></head><body><div id="a"><div>前</div><div>後</div><div>上</div><div>下</div><div>左</div><div>右</div></div></body><script type="text/javascript">var a=document.getElementById("a")var x;var y;a.onmousedown=function(ev){ //在div上摁下時x=ev.clientX //擷取當前滑鼠的位置y=ev.clientYdocument.onmousemove=function(ev){//滑鼠移動時var x1=ev.clientX-x+30 //當前位置減去下時滑鼠的位置，就擷取移動了多少度，應為一開始有初始角度所以加30° var y1=ev.clientY-y-30 //甚至樣式每次滑鼠移動式更改樣式a.style.transform="perspective(1000px) rotateY("+ x1 +"deg) rotateX("+ -(y1) +"deg)";}document.onmouseup=function(){document.onmousemove=null;}}</script></html> 效果
