javascript – 输入的插入符高度

我需要帮助才能改变插入符号的高度,而不会改变视觉(只要工作时允许使用黑客/技巧).这就意味着我不想更改字体的大小(高度和宽度),边距,颜色,背景,边框等,如果我改变它来实现插入符号的风格,可以让我可以把它像普通的输入一样,具有它的造型能力.

我最好的尝试是以下代码：

body{
  background-color: lightBlue;
}
#background{
  color: red;
  height: 61px;
  margin-top: 0px;
  text-shadow: 0 0 0 transparent;
  width: 173px;
  -webkit-text-fill-color: transparent;
  -webkit-transform: scale(1,calc(1/3));
}
#text{
  background-color: transparent;
  border-color: transparent;
  color: red;
  left: 8px;
  pointer-events: none;
  position: absolute;
  top: 103px;
}

<span>Caret's height (pixels):</span>
<br>
<br>
<input placeholder="15 (default)" spellcheck="false">
<br>
<br>
<input id="background" oninput="document.getElementById('text').value=this.value" spellcheck="false">
<input id="text" placeholder="5 (1/3)" onfocus="this.blur()" spellcheck="false" tabindex="-1">

如果需要,请忽略文本的选择异常.我现在不在乎.

如果你有一个更好的解决方案,让我知道.这只是我一直在做的一些测试,我不完全需要颜色为红色,其他属性是他们的方式,但我仍然希望将其更改为我想要的.

如果人们不一样(使用Chrome),这是如何看待我的：

解决方法

可以通过“黑客”来完成.

而不是输入框,您需要使用javascript,css和span的组合
