今天寫點(diǎn)css3，3d屬性寫的3d盒子，結(jié)合javascript讓盒子隨鼠標(biāo)旋轉(zhuǎn)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(duì)定位*/ transform-style: preserve-3d; /*父元素設(shè)為3d*/ transform: perspective(1000px) rotateY(30deg) rotateX(30deg); /*設(shè)置父元素得景深*/ } #a>div{ position:absolute;/*盒子每面的默認(rèn)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);/*第二元素向后位移100px 這樣盒子前后面就有了*/ background: rgba(0,255,0,0.2); } #a>div:nth-child(3){ transform: rotateX(90deg) translateZ(100px);/*第三個(gè)讓他平躺下，也就是x軸旋轉(zhuǎn)90°，旋轉(zhuǎn)后在位移，這樣就會(huì)向他面對(duì)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(jié)就是先旋轉(zhuǎn)在位移，z軸就是div面向那面那面將會(huì)是z所以說先旋轉(zhuǎn)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>后</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(shí) x=ev.clientX //獲取當(dāng)前鼠標(biāo)的位置 y=ev.clientY document.onmousemove=function(ev){//鼠標(biāo)移動(dòng)時(shí) var x1=ev.clientX-x+30 //當(dāng)前位置減去下時(shí)鼠標(biāo)的位置，就獲取移動(dòng)了多少度，應(yīng)為一開始有初始角度所以加30° var y1=ev.clientY-y-30 //甚至樣式每次鼠標(biāo)移動(dòng)式更改樣式 a.style.transform="perspective(1000px) rotateY("+ x1 +"deg) rotateX("+ -(y1) +"deg)"; } document.onmouseup=function(){ document.onmousemove=null; } } </script> </html>
