Membuat Collapsible Content

Terkadang kita perlu untuk membuat sebuah collapsible content pada website, misalnya untuk keperluan meringkas konten pada halaman yg panjang. Ada banyak cara yang bisa digunakan untuk hal tersebut, salah satu di antaranya dengan memakai pure css. Kita butuh HTML dan CSS untuk melakukannya.

Begini CSS-nya:

.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;
}

Lalu untuk HTML-nya begini:

<div class="wrap-collabsible">
  <input id="collapsible" class="toggle" type="checkbox">
  <label for="collapsible" class="lbl-toggle">More Info</label>
  <div class="collapsible-content">
    <div class="content-inner">
      <p>
