html - 展开/最小化 Accordion 无法正常工作

Question

我创建了一个 Accordion ，但是当我选择尝试最小化“按钮 2”时，它反而最小化了“按钮 1”。但是，当我尝试最小化“按钮 1”时，它会自行最小化。我在 JS Fiddle 上发布了代码供您引用，这样您就可以看到它的实际效果:

知道我做错了什么以及如何解决这个问题，以便 Button 2 正确地最小化自身并且不影响 Button 1 吗？

HTML:

<div class="wrap-collabsible">
    <input checked="checked" class="toggle" id="collapsible" type="checkbox" checked> <label class="lbl-toggle" for="collapsible" tabindex="0">Button 1</label>
    <div class="collapsible-content">
        <div class="content-inner">
            <p>Test 1</p>
        </div>
    </div>
</div>

CSS:

.wrap-collabsible {
  margin-bottom: 1.2rem 0;
}

input[type='checkbox'] {
  display: none;
}

.lbl-toggle {
  display: block;

  font-weight: bold;
  font-family: monospace;
  font-size: 1.2rem;
  text-transform: uppercase;
  text-align: center;

  padding: 1rem;

  color: #A77B0E;
  background: #FAE042;

  cursor: pointer;

  border-radius: 7px;
  transition: all 0.25s ease-out;
}

.lbl-toggle:hover {
  color: #7C5A0B;
}

.lbl-toggle::before {
  content: ' ';
  display: inline-block;

  border-top: 5px solid transparent;
  border-bottom: 5px solid transparent;
  border-left: 5px solid currentColor;
  vertical-align: middle;
  margin-right: .7rem;
  transform: translateY(-2px);

  transition: transform .2s ease-out;
}

.toggle:checked + .lbl-toggle::before {
  transform: rotate(90deg) translateX(-3px);
}

.collapsible-content {
  max-height: 0px;
  overflow: hidden;
  transition: max-height .25s ease-in-out;
}

.toggle:checked + .lbl-toggle + .collapsible-content {
  max-height: 350px;
}

.toggle:checked + .lbl-toggle {
  border-bottom-right-radius: 0;
  border-bottom-left-radius: 0;
}

.collapsible-content .content-inner {
  background: rgba(250, 224, 66, .2);
  border-bottom: 1px solid rgba(250, 224, 66, .45);
  border-bottom-left-radius: 7px;
  border-bottom-right-radius: 7px;
  padding: .5rem 1rem;
}

Answer 1

在您的 html 中，您为“按钮 1”和“按钮 2”输入分配了相同的“可折叠”ID。为每个输入分配唯一的 ID(并更正相应的标签 html)应该可以解决您的问题。

例如:

.wrap-collabsible {
  margin-bottom: 1.2rem 0;
}

input[type='checkbox'] {
  display: none;
}

.lbl-toggle {
  display: block;
  font-weight: bold;
  font-family: monospace;
  font-size: 1.2rem;
  text-transform: uppercase;
  text-align: center;
  padding: 1rem;
  color: #A77B0E;
  background: #FAE042;
  cursor: pointer;
  border-radius: 7px;
  transition: all 0.25s ease-out;
}

.lbl-toggle:hover {
  color: #7C5A0B;
}

.lbl-toggle::before {
  content: ' ';
  display: inline-block;
  border-top: 5px solid transparent;
  border-bottom: 5px solid transparent;
  border-left: 5px solid currentColor;
  vertical-align: middle;
  margin-right: .7rem;
  transform: translateY(-2px);
  transition: transform .2s ease-out;
}

.toggle:checked + .lbl-toggle::before {
  transform: rotate(90deg) translateX(-3px);
}

.collapsible-content {
  max-height: 0px;
  overflow: hidden;
  transition: max-height .25s ease-in-out;
}

.toggle:checked + .lbl-toggle + .collapsible-content {
  max-height: 350px;
}

.toggle:checked + .lbl-toggle {
  border-bottom-right-radius: 0;
  border-bottom-left-radius: 0;
}

.collapsible-content .content-inner {
  background: rgba(250, 224, 66, .2);
  border-bottom: 1px solid rgba(250, 224, 66, .45);
  border-bottom-left-radius: 7px;
  border-bottom-right-radius: 7px;
  padding: .5rem 1rem;
}

<div class="wrap-collabsible">
      <input checked="checked" class="toggle" id="collapsible1" type="checkbox" checked> 
      <label class="lbl-toggle" for="collapsible1" tabindex="0">Button 1</label>
      <div class="collapsible-content">
        <div class="content-inner">
          <p>Test 1</p>
        </div>
      </div>
    </div>
      
    <div class="wrap-collabsible">
      <input checked="checked" class="toggle" id="collapsible2" type="checkbox" checked> 
      <label class="lbl-toggle" for="collapsible2" tabindex="0">Button 2</label>
      <div class="collapsible-content">
        <div class="content-inner">
          <p>Test 2</p>
        </div>
      </div>
    </div>
