html - 列表项元素符号点重复

标签 html css list

我正在构建这个简单的表单(从这里获取代码 https://codepen.io/JeromeRenders/pen/EPNxPv )但是要点最终在我的页面上重复了。怎么会？下面是表单的 html 和我正在使用的 css。谢谢。我还添加了 JS，因为这是创建 li 列表的原因。

body fieldset {
  box-shadow: 0 8px 10px #29a329;
}

body.error {
  background: #f04000;
}

body.error fieldset {
  box-shadow: 0 8px 10px #bd3200;
}

ul.items {
  position: absolute;
  width: 30px;
  height: auto;
  top: 50%;
  left: -60px;
  transform: translateY(-50%);
}

ul.items li {
  width: 8px;
  height: 8px;
  margin: 10px 0;
  background: white;
  border-radius: 50%;
  opacity: 0.4;
  cursor: pointer;
}

ul.items li.active {
  opacity: 1;
}

form {
  position: relative;
  width: 300px;
  height: 60px;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}

form fieldset {
  position: absolute;
  width: 300px;
  height: 60px;
  background: white;
  border-radius: 3px;
  opacity: 0;
  transform: scale(0.2);
  transition: all 0.4s ease-in-out;
}

form fieldset input,
form fieldset p {
  display: inline-block;
  width: 200px;
  margin-left: 50px;
  color: #333333;
  font-size: 16px;
  letter-spacing: 1px;
}

form fieldset p {
  margin-top: 22px;
  text-align: center;
}

form fieldset input {
  height: 40px;
  margin-top: 8px;
  border: none;
  outline: none;
}

body.error fieldset {
  transform-origin: 50% 100%;
  animation: error 0.3s ease-out;
}
<form>
  <ul class="items"></ul>
  <fieldset class="username enable">
    <div class="icon left"><i class="user"></i></div>
    <input type="text" name="username" placeholder="Username" />
    <div class="icon right button"><i class="arrow"></i></div>
  </fieldset>
  <fieldset class="email">
    <div class="icon left"><i class="letter"></i></div>
    <input type="mail" name="email" placeholder="Email" />
    <div class="icon right button"><i class="arrow"></i></div>
  </fieldset>
  <fieldset class="thanks">
    <div class="icon left"></div>
    <p>Thanks for your time</p>
    <div class="icon right"></div>
  </fieldset>
  </form>

JS

    function init() {
  // Generate li foreach fieldset
  for (var i = 0; i < count; i++) {
    var ul = document.querySelector('ul.items'),
    li = document.createElement("li");

    ul.appendChild(li);
  }
 // Add class active on first li
  ul.firstChild.classList.add('active');
}

这是我得到的图像: Duplicated bullet points

最佳答案

下面的代码对此很有用: CSS:

body fieldset {

body.error fieldset {
