This time I will bring you css3+js to realize 3D planetary operation. What are the precautions for css3+js to realize 3D planetary operation? The following is a practical case, let’s take a look.
HTML part
<p class="path-Saturn"> <p id="Saturn" title="土星"> <p class="x"></p> <p class="y"></p> <p class="z"></p> <p class="space space-x"></p> <p class="space space-x1"></p> <p class="space space-x2"></p> <p class="space space-y"></p> <p class="space space-y1"></p> <p class="space space-y2"></p> <p class="space space-z"></p> <p class="space space-z1"></p> <p class="space space-z2"></p> <!-- 卫星 --> <p class="path-satellite"> <p id="satellite" title="卫星"> <p class="x"></p> <p class="y"></p> <p class="z"></p> <p class="space space-x"></p> <p class="space space-x1"></p> <p class="space space-x2"></p> <p class="space space-y"></p> <p class="space space-y1"></p> <p class="space space-y2"></p> <p class="space space-z"></p> <p class="space space-z1"></p> <p class="space space-z2"></p> </p> </p> </p> </p>
