CSS3的3D转换效果详解介绍:
本章介绍一下CSS3的3D转换效果,此效果的实现依靠的是transform属性,3D转换只是此属性的部分应用,更多相关内容可以参阅CSS3的transform属性总略介绍一章节。
掌握3D转换效果,可以从三个方法作为突破口,分别是rotateX, rotateY, rotateZ,在2D变换过程中rotate()函数的应用,它表示旋转的意思,由于是2D变换,所以它只是在一个平面进行旋转,所以无需细分,具体可以参阅CSS3的2D转换效果详细介绍一章节。 下面分别介绍一下上面的三个旋转方法。
一.rotateX()方法:
<!DOCTYPE html> <html> <head> <meta charset=" utf-8"> <meta name="author" content="http://www.softwhy.com/" /> <title>蚂蚁部落</title> <style type="text/css"> #box{ position:relative; height:200px; width:200px; margin-top:150px; margin-left:150px; border:1px solid black; } #inner{ padding:50px; position:absolute; border:1px solid black; background-color:yellow; font-size:12px; transform-origin:0px 0px; -ms-transform-origin:0px 0px; -webkit-transform-origin:0px 0px; -o-transform-origin:0px 0px; -moztransform-origin:0px 0px; transform:rotateX(0deg); -ms-transform:rotateX(0deg); -webkit-transform:rotateX(0deg); -o-transform:rotateX(0deg); -moz-transform:rotateX(0deg);} table{ font-size:12px; width:300px; margin-left:120px; } .left{text-align:right} </style> <script type="text/javascript"> function changeRot(value){ var oinner=document.getElementById('inner'); var opersp=document.getElementById('persp'); oinner.style.transform="rotateX(" + value + "deg)"; oinner.style.msTransform="rotateX(" + value + "deg)"; oinner.style.webkitTransform="rotateX(" + value + "deg)"; oinner.style.MozTransform="rotateX(" + value + "deg)"; oinner.style.OTransform="rotateX(" + value + "deg)"; opersp.innerHTML=value + "deg"; } window.onload=function(){ var range=document.getElementById("range"); range.onmousemove=function(){ changeRot(this.value); } } </script> </head> <body> <div id="box"> <div id="inner">蚂蚁部落</div> </div> <table> <tr> <td class="left">旋转:</td> <td><input type="range" min="-360" max="360" id="range" value="0"/></td> </tr> <tr> <td class="left">rotateX:</td> <td>(<span id="persp">0deg</span>)</td> </tr> </table> </body> </html>
以上代码演示了rotateX()的作用,他可以控制元素围绕着x轴进行旋转,就像是一个体操运动员,在单杠上旋转一样。
二.rotateY()方法:
<!DOCTYPE html> <html> <head> <meta charset=" utf-8"> <meta name="author" content="http://www.softwhy.com/" /> <title>蚂蚁部落</title> <style type="text/css"> #box{ position:relative; height:200px; width:200px; margin-top:150px; margin-left:150px; border:1px solid black; } #inner{ padding:50px; position:absolute; border:1px solid black; background-color:yellow; font-size:12px; transform-origin:0px 0px; -ms-transform-origin:0px 0px; -webkit-transform-origin:0px 0px; -o-transform-origin:0px 0px; -moztransform-origin:0px 0px; transform:rotateY(0deg); -ms-transform:rotateX(0deg); -webkit-transform:rotateY(0deg); -o-transform:rotateY(0deg); -moz-transform:rotateY(0deg);} table{ font-size:12px; width:300px; margin-left:120px; } .left{text-align:right} </style> <script type="text/javascript"> function changeRot(value){ var oinner=document.getElementById('inner'); var opersp=document.getElementById('persp'); oinner.style.transform="rotateY(" + value + "deg)"; oinner.style.msTransform="rotateY(" + value + "deg)"; oinner.style.webkitTransform="rotateY(" + value + "deg)"; oinner.style.MozTransform="rotateY(" + value + "deg)"; oinner.style.OTransform="rotateY(" + value + "deg)"; opersp.innerHTML=value + "deg"; } window.onload=function(){ var range=document.getElementById("range"); range.onmousemove=function(){ changeRot(this.value); } } </script> </head> <body> <div id="box"> <div id="inner">蚂蚁部落</div> </div> <table> <tr> <td class="left">旋转:</td> <td><input type="range" min="-360" max="360" id="range" value="0"/></td> </tr> <tr> <td class="left">rotateY:</td> <td>(<span id="persp">0deg</span>)</td> </tr> </table> </body> </html>
以上代码演示了rotateY()的作用,他可以控制元素围绕着y轴进行旋转,就像是一个钢管舞演员在竖直的钢管上旋转。
三.rotateZ()方法:
<!DOCTYPE html> <html> <head> <meta charset=" utf-8"> <meta name="author" content="http://www.softwhy.com/" /> <title>蚂蚁部落</title> <style type="text/css"> #box{ position:relative; height:200px; width:200px; margin-top:150px; margin-left:150px; border:1px solid black; } #inner{ padding:50px; position:absolute; border:1px solid black; background-color:yellow; font-size:12px; transform-origin:0px 0px; -ms-transform-origin:0px 0px; -webkit-transform-origin:0px 0px; -o-transform-origin:0px 0px; -moztransform-origin:0px 0px; transform:rotateZ(0deg); -ms-transform:rotateZ(0deg); -webkit-transform:rotateZ(0deg); -o-transform:rotateZ(0deg); -moz-transform:rotateZ(0deg);} table{ font-size:12px; width:300px; margin-left:120px; } .left{text-align:right} </style> <script type="text/javascript"> function changeRot(value){ var oinner=document.getElementById('inner'); var opersp=document.getElementById('persp'); oinner.style.transform="rotateZ(" + value + "deg)"; oinner.style.msTransform="rotateZ(" + value + "deg)"; oinner.style.webkitTransform="rotateZ(" + value + "deg)"; oinner.style.MozTransform="rotateZ(" + value + "deg)"; oinner.style.OTransform="rotateZ(" + value + "deg)"; opersp.innerHTML=value + "deg"; } window.onload=function(){ var range=document.getElementById("range"); range.onmousemove=function(){ changeRot(this.value); } } </script> </head> <body> <div id="box"> <div id="inner">蚂蚁部落</div> </div> <table> <tr> <td class="left">旋转:</td> <td><input type="range" min="-360" max="360" id="range" value="0"/></td> </tr> <tr> <td class="left">rotateZ:</td> <td>(<span id="persp">0deg</span>)</td> </tr> </table> </body> </html>
以上代码演示了rotateZ()的作用,他可以控制元素围绕着z轴进行旋转,关于Z轴,学过立体几何的应该都比较清楚了,随便百度一下就知道了。上面三个代码已经比较清晰的演示了三个旋转函数的作用。

HTML, CSS and JavaScript are the three pillars of web development. 1. HTML defines the web page structure and uses tags such as, etc. 2. CSS controls the web page style, using selectors and attributes such as color, font-size, etc. 3. JavaScript realizes dynamic effects and interaction, through event monitoring and DOM operations.

HTML defines the web structure, CSS is responsible for style and layout, and JavaScript gives dynamic interaction. The three perform their duties in web development and jointly build a colorful website.
