我真的不知道如何描述我的问题，但基本上:

为了好玩，我在 JSFiddle 中编写了一个元素，不知何故我的代码输出只是上下跳动。

如果您想亲自查看，请单击下面的链接，然后单击“提交投诉”按钮。

问题是:在输出文本中，一些变量和文本高于周围的所有文本。我不知道为什么。

感谢您的帮助!

My project on JSFiddle

这是一个工作片段:

$("#textChanger").click(function() {	
	      	      
 var el     = $("#alarmcard"),  
     newone = el.clone(true);
           
 el.before(newone);
        
 $("." + el.attr("class") + ":last").remove();

});

$("input:checkbox").on('click', function() {
  // in the handler, 'this' refers to the box clicked on
  var $box = $(this);
  if ($box.is(":checked")) {
    // the name of the box is retrieved using the .attr() method
    // as it is assumed and expected to be immutable
    var group = "input:checkbox[name='" + $box.attr("name") + "']";
    // the checked state of the group/box on the other hand will change
    // and the current value is retrieved using .prop() method
    $(group).prop("checked", false);
    $box.prop("checked", true);
  } else {
    $box.prop("checked", false);
  }
});
.fieldset {
  visibility:hidden;
}

.typewriter {
  vertical-align: baseline;
  display: flex;
  color: black;
  font-family: monospace;
  overflow: hidden;
  /* Ensures the content is not revealed until the animation */
  border-right: .15em solid orange;
  /* The typwriter cursor */
  white-space: nowrap;
  /* Keeps the content on a single line */
  margin: 0 auto;
  /* Gives that scrolling effect as the typing happens */
  letter-spacing: .15em;
  /* Adjust as needed */
  animation: typing 3.5s steps(30, end), blink-caret .5s step-end infinite;
}

/* 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: orange
  }
}

最佳答案

问题是你没有任何 <p></p>围绕你的 DIV 中的文本( #firstDiv 、 #SecondDiv 等)。

这是一个最小的、完整的和可验证的片段，您可以在其中看到使用/不使用 <p></p> 的差异 :

.typewriter {
  vertical-align: baseline;
  display: flex;
  color: black;
  font-family: monospace;
  overflow: hidden;
  /* Ensures the content is not revealed until the animation */
  border-right: .15em solid orange;
  /* The typwriter cursor */
  white-space: nowrap;
  /* Keeps the content on a single line */
  margin: 0 auto;
  /* Gives that scrolling effect as the typing happens */
  letter-spacing: .15em;
  /* Adjust as needed */
  animation: typing 3.5s steps(30, end), blink-caret .5s step-end infinite;
}
<div class="typewriter">
  <p>Start |&nbsp;</p>
  <div id="firstDiv">
    <p>Test 1</p>
  </div>
  <p>&nbsp;| end.</p>
</div>
<br/>
<div class="typewriter">
  <p>Start |&nbsp;</p>
  <div id="firstDiv">Test 2</div>
  <p>&nbsp;| end.</p>

</div>
