如何创建跨多行文本的CSS输入动画? [英] How to create a CSS typing animation that spans multiple lines of text?

问题描述

当父容器的大小迫使文本跨越多行时，我试图使键入动画效果连续一行.

I am trying to get the typing animation effect to continue one line at a time when the size of parent container forces the text to span multiple lines.

/* The typing effect */
@keyframes typing {
  from {
    width: 0;
  }
  to {
    width: 100%;
  }
}

/* The typewriter cursor effect */
@keyframes blink-caret {
  from,
  to {
    border-color: transparent;
  }
  50% {
    border-color: green;
  }
}

.animated-text {
  font: bold 1.45em monospace;
  color: black;
  border-right: 0.6em solid;
  overflow: hidden; /* Ensures the content is not revealed until the animation */
  margin: 0 auto; /* Gives that scrolling effect as the typing happens */
  animation: typing 3.5s steps(40, end), blink-caret 0.9s step-end infinite;
}

.container {
  border: 10px solid;
  position: absolute;
  width: 25%;
  height: 32%;
  left: 35%
}

  <div class='container'>
        <h1 class='animated-text'>The typing effect should continue line by line at a time when the text needs to wrap</h1>
      </div>

推荐答案

我也一直在寻找该问题的答案.

I've been searching for the answer to this question as well.

我能找到的最接近的是这是多行打字机效果.但是，您必须手动设置每个p标签的宽度.我还没有找到一种动态设置每行宽度的方法.

The closest I could find was this - multiline typewriter effect. However, you have to manually set the width of each p tag. I've yet to find a way to dynamically set the width of each line.

除最后一行外，所有行均使用右边框显示打字机效果，只有最后一行具有闪烁动画，即打字机光标.

All lines except for the last line uses border-right to display the typewriter effect, only the last line has blink animation which is the typewriter cursor.
