使用transform创建干净的立方体

问题描述 投票：2回答：1

所以有很多与此相关的帖子，但我似乎无法准确确定我的风格出错的地方，所以如果有些人认为这是对以前问题的重复，那么道歉。

这个问题非常简单：我只是试图建立一个随机骰子卷。 js按预期工作，一切正常。问题是立方体看起来很尴尬，我不完全确定原因。我通常对css非常扎实，但是我没有做很多关于3d变换的工作，因此我缺乏直觉。如果您运行该片段，您可以看到当立方体旋转时并非所有侧面都是平滑的，有些侧面看起来是凹陷的，我不确定为什么（特别是1和2侧）。完整代码位于以下代码段中：

const rollBtn = document.getElementById('roll');
const sides = ['one', 'two', 'three', 'four', 'five', 'six'];
const output = document.getElementById('dice_output');
let currentClass = '';

const rollDice = () => {
  let randomSide = sides[Math.floor(Math.random() * (6) + 1)];
  let currentSide = document.getElementById(randomSide);
  let generatedSide = `show-${randomSide}`;
  if (currentClass) {
    output.classList.remove(currentClass);
  }
  output.classList.add(generatedSide);
  currentClass = generatedSide;
}

rollBtn.addEventListener('click', rollDice);
* {
  box-sizing: border-box;
}

  content: "";

}

  width: 80px;
  margin: 2% auto;

你还需要将#one和#two翻译成40px

const rollBtn = document.getElementById('roll');
const sides = ['one', 'two', 'three', 'four', 'five', 'six'];
const output = document.getElementById('dice_output');
let currentClass = '';

const rollDice = () => {
  let randomSide = sides[Math.floor(Math.random() * (6) + 1)];
  let currentSide = document.getElementById(randomSide);
  let generatedSide = `show-${randomSide}`;
  if (currentClass) {
    output.classList.remove(currentClass);
  }
  output.classList.add(generatedSide);
  currentClass = generatedSide;
  
}

rollBtn.addEventListener('click', rollDice);
* {
  box-sizing: border-box;
}

.clearfix:after {
  content: "";
  display: table;
  clear: both;
}

.container {
  width: 80px;
  margin: 5% auto;
  text-align: center;
}

.stage {
  width: 80px;
  height: 80px;
  perspective: 300px;
}

.btn-container {

.the-big-z {

.the-die {

  color: #fff;
  background-color: #000;

}

#one {

}
#two { 
  transform: rotateY( 90deg) translateZ(40px); // And here
}
#three { 
  transform: rotateY(180deg) translateZ(40px);

#four { 
  transform: rotateY(-90deg) translateZ(40px);
