添加多个可变字并将文本居中


在这个动画中，我模拟打字机（只有HTML/CSS），我想添加4个更多的变量书写，但我不能，因为我不明白如何工作与关键帧。 我试过了，但他同时写了几个字。

第二个问题是，我不能确切地把“嗨，我是A”放在中间，当它必须写变量词的时候，让它移到左边。 （示例:https://codepen.io/sheikh_ishaan/pen/lyeoqjd）

步骤2详细说明

Usage-要加减的%值定义光标改变单词的时间

(i)正如你已将你的持续时间除以编号。 你需要4个单词，然后你必须为每个类分配一个范围，就像我给.text-1分配了0%-25%。

~步骤(i)的含义-您正在指定该特定单词动画的时间限制。

ii）现在在这个范围内添加和减去一个固定值，就像在@keyframes.text_1的下一行中，我在下限上添加5%，在上限上减去5%，ex-(0+5)%，(25-5)%

前-

@keyframes text1 {
  0%, 25%, 50%, 75%, 100% {
    width: 0;
  }
  5%, 20% {
    width: 8em;
  }
}

~步骤(ii)的含义-你的动画将在总时间的5%-20%的范围内发生。。。 为了使动画流畅运行，需要这样的加减法。

(iii)类似地，在为每个类指定一个指定的持续时间范围后，对每个类执行同样的操作。

text_3为例，其用量为50%-75%，因此其平稳运行的极限为-(50+5)%-(75-5)%=55%-70%-

@keyframes text3 {
  0%, 25%, 50%, 75%, 100% {
    width: 0;
  }

  55%, 70% {
    width: 6.75em;
  }
}

现在，最后8个元素的代码。。。 希望你现在能更好地理解它！！
