3d cube rotation based on CSS3 new attribute transform
Through the native JS, click on the event, mouse down, mouse lift and mouse movement events, to achieve 3d cube drag rotation, and the rotation angle of the real-time reaction to the interface display
Implementation principle: By getting the mouse to click on the screen and the coordinates of the mouse movement, to get the mouse in the x-axis, the y-axis movement distance, the distance real-time assignment to the Transform property
Thus, the effect of 3d cube rotation can be achieved by changing the Transform:rotate attribute value.
HTML code block:
<body> <input type= "button" class= "Open" value= "click Spread"/> <input type= "text" class= "Xnum" value = "0"/>//x axis rotation angle <input type= "text" class= "ynum" value= "0"/>//y axis rotation angle <input type= "text" class= " Znum "/> <div class=" Big_box "> <div class=" box "> <span>1</span> < span>2</span> <span>3</span> <span>4</span> <span>5</ span> <span>6</span> </div> </div></body>
