html - 在底部对齐文本

Question

我无法对齐底部的文本。

.container {
  margin: auto;
  border-radius: 25px;
  width: 320px;
  height: 480px;
  background-color: lightgrey;
  background-image: url("https://raw.githubusercontent.com/zumartic/calculator/master/calculator.jpg");
  box-shadow: 10px 10px 5px #888888;
}
.head {
  width: 320px;
  height: 45px;
  color: yellow;
  font-size: 200%;
  font-weight: bold;
  text-align: center;
}
.display1 {
  width: 320px;
  height: 45px;
  font-size: 200%;
  font-weight: bold;
  margin-left: -5px;
  text-align: right;
}
.display2 {
  width: 320px;
  height: 90px;
}
#D2-content {
  width: 320px;
  font-size: 200%;
  word-wrap: break-word;
  font-weight: bold;
  text-align: right;
  margin-left: -1px;
  vertical-align: bottom;
}

<div class="container">
  <div class="head" id="head">FCC Calculator</div>
  <div class="display1" id="display1"></div>
  <div class="display2" id="display2">
    <div id="D2-content">0</div>
  </div>
  <hr>
  <div class="button-item" id="CE">CE</div>
  <div class="button-item" id="C">C</div>
  <div class="button-item"></div>
  <div class="button-item"></div>
  <div class="button-item" id="7">7</div>
  <div class="button-item" id="8">8</div>
  <div class="button-item" id="9">9</div>
  <div class="button-item" id="divide">/</div>
  <div class="button-item" id="4">4</div>
  <div class="button-item" id="5">5</div>
  <div class="button-item" id="6">6</div>
  <div class="button-item" id="multiply">*</div>
  <div class="button-item" id="1">1</div>
  <div class="button-item" id="2">2</div>
  <div class="button-item" id="3">3</div>
  <div class="button-item" id="minus">-</div>
  <div class="button-item" id="0">0</div>
  <div class="button-item" id="point">.</div>
  <div class="button-item" id="equal">=</div>
  <div class="button-item" id="plus">+</div>
</div>

我想先对齐 D2-content 元素中的文本。我已经尝试使用表格并且可以在底部对齐，但是自动换行不再起作用。有什么建议吗？

将position:absolute 添加到您要移动的内容。并将 position:relative 添加到父元素。

.container {
    margin: auto;
    border-radius: 25px;
    width: 320px;
    height: 480px;
    background-color: lightgrey;
    background-image: url("https://raw.githubusercontent.com/zumartic/calculator/master/calculator.jpg");
    box-shadow: 10px 10px 5px #888888;
}

.head {  
    width: 320px;
    height: 45px;
    color: yellow;
    font-size: 200%;
    font-weight: bold;
    text-align: center;
}

.display1 {  
    width: 320px;
    height: 45px; 
    font-size: 200%;
    font-weight: bold;
    margin-left: -5px;
    text-align: right;
}

.display2 { 
    width: 320px;
    height: 90px;
    position:relative;
}

#D2-content {
    width: 320px;
    font-size: 200%;
    word-wrap: break-word;
    font-weight: bold;
    text-align: right;
    margin-left: -1px;
    
    position:absolute;
    bottom:0;
  }

    <div class="button-item" id="plus">+</div>
</div>
