"Read More" 按钮位置在点击时出错。？

Question

我已经实现了一个可折叠的 div，它会在单击 "Read More" 按钮时展开。它工作正常。但是通过扩展按钮位置出错了。当卡片未展开时，我希望按钮位于卡片上按钮所在的相同位置。

这是我的代码

 * {
  font-family: verdana, sans-serif;
}

#more {
  display: none;
}

.wrap-collabsible {
  margin-bottom: 1.2rem 0;
  margin-top: 40px;
}

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

#myBtn {
  display: block;
  float: right;
  font-weight: bold;
  font-family: Verdana, sans-serif;
  text-transform: uppercase;
  text-align: center;
  border: none;
  padding: 1rem;
  outline: none;
  color: #A77B0E;
  background: #FAE042;

  cursor: pointer;

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

#myBtn: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;
}

.Add {
  font-weight: bolder;
}

.wrapper {
  padding: 0px 15px 0px 15px;
  display: table-cell;
}

.box {
  padding: 10px;
  box-shadow: 5px 4px 9px 0px #d8d7d7;
  border: 1px solid #eeee;
}

.inner-box {
  width: 30%;
  float: left;
  display: table-cell;
}

.Text-box {
  font-family: verdana, sans-serif;
  margin-top: -16px;
}

.Add-text {
  font-weight: bolder;
}

.text {
  color: blue;
}

.img {
  max-width: 88%;
  height: auto;
}

#conditional-tag {
  display: none;
}

<div Class="box">
<p class="Add" id="conditional-tag">No. 60, Jalan Pendamar Indah 1B, Taman Pendamar Indah, Pelabuhan Klang, Selangor </p>
<div class="inner-box">

  <button onclick="myFunction()" id="myBtn">Read more ></button>

    function myFunction() {
      var dots = document.getElementById("dots");
      var moreText = document.getElementById("more");
      var btnText = document.getElementById("myBtn");
      document.getElementById('hideOnClick').innerHTML = "Hello to the world";
      document.getElementById('conditional-tag').style.display = "block";
      if (dots.style.display === "none") {
        dots.style.display = "inline";
        btnText.innerHTML = "Read more";
        moreText.style.display = "none";
        document.getElementById('hideOnClick').innerHTML = "No. 60, Jalan Pendamar Indah 1B, Taman Pendamar Indah, Pelabuhan Klang, Selangor";
        document.getElementById('conditional-tag').style.display = "none";
      } else {
        dots.style.display = "none";
        btnText.innerHTML = "Read less >";
        moreText.style.display = "inline";
      }
    }
  </script>
</div>
  </div>

我想要卡片折叠前后相同位置的按钮。我怎样才能得到它？

Answer 1

这里我删除了 float: right 并添加了 position:relative; 并设置了 right:250px; .

 * {
  font-family: verdana, sans-serif;
}

#more {
  display: none;
}

.wrap-collabsible {
  margin-bottom: 1.2rem 0;
  margin-top: 40px;
}

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

#myBtn {
  position: relative;
  left: 250px;
  display: block;
  font-weight: bold;
  font-family: Verdana, sans-serif;
  text-transform: uppercase;
  text-align: center;
  border: none;
  padding: 1rem;
  outline: none;
  color: #A77B0E;
  background: #FAE042;

  cursor: pointer;

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

#myBtn: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;
}

.Add {
  font-weight: bolder;
}

.wrapper {
  padding: 0px 15px 0px 15px;
  display: table-cell;
}

.box {
  padding: 10px;
  box-shadow: 5px 4px 9px 0px #d8d7d7;
  border: 1px solid #eeee;

.inner-box {
  width: 30%;
  float: left;
  display: table-cell;
}

.Text-box {
  font-family: verdana, sans-serif;
  margin-top: -16px;
}

.Add-text {
  font-weight: bolder;
}

.text {
  color: blue;
}

.img {
  max-width: 88%;
  height: auto;
}

#conditional-tag {
  display: none;
}

<div Class="box">

      } else {
        dots.style.display = "none";
        btnText.innerHTML = "Read less >";
        moreText.style.display = "inline";
      }
    }
  </script>
</div>
  </div>

Answer 2

您只需要用类包装您的 div - 内盒和容器内的包装纸 div 这将解决您的问题。当前的问题是您的包装器 div 没有占用 100% 的宽度，因此您看到 'Read Less' 按钮的位置不正确。

<div>
    <div class="inner-box">
        <!-- your existing code here -->
    </div>
    <div class="wrapper">
        <!-- your existing code here -->
    </div>
</div>
