Question

我需要隐藏部分超过 2 行的文本并添加'...123 T.'为隐藏溢出的指示符，如下所示：

到目前为止我所拥有的：https ://plnkr.co/edit/NTlv4NpyhRTzJkNQ?preview

html:

<div class="outside-container">
      <span class="container">
        <span class="main-text">
          Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nam metus mi,
          dapibus sit amet posuere eu, porttitor condimentum nulla. Donec
          convallis lorem justo, eget malesuada lorem tempor vitae. Aliquam
          sollicitudin lacus ipsum, at tincidunt ante condimentum vitae.
        </span>
        <span class="small-text">123 T.</span>
      </span>

      <span class="container">
        <span class="main-text">
          Lorem ipsum
        </span>
        <span class="small-text">123 T.</span>
      </span>

      <span class="container">
        <span class="main-text">
          Lorem ipsum dolor sit ameta,  adipiscing elit. Nam metus
        </span>
        <span class="small-text">123 T.</span>
      </span>
</div>

CSS：

.outside-container {
  width: 200px;
}

.container{
  max-width: 200px;
}

.main-text {
  overflow: hidden;
  vertical-align: middle;
  text-overflow: ellipsis;
  display: -webkit-box;
  -webkit-line-clamp: 2;
  -webkit-box-orient: vertical;
}

.small-text {
  color: #8e8f8f ;
  font-size: 10px;
  vertical-align: middle;
}

将来，您只需使用一行代码就可以做到这一点：

line-clamp: 2 "...123 T.";

您可以在规范中找到更多详细信息：

line-clamp 属性是max-lines、block-ellipsis和continue属性的简写。

它允许将块容器的内容限制为指定的行数；剩余的内容被分割掉，既不渲染也不测量。可选地，它还允许在最后一行框中插入内容以指示截断/中断内容的连续性。

在那之前，这是一个非常老套的想法来实现结果：

.container {
  max-width: 200px;
  margin: 5px;
}

.main-text {
  line-height: 1.2em; /* the height of a line */
  max-height: calc(2 * 1.2em); /* restrict the height to 2 lines*/
  overflow: hidden;
  display: inline-block;
  position: relative;
}

.main-text:after {
  content: "123 T.";
  display:inline-block;
  width:40px;
  position:relative;
  z-index:999;
  /* a big box-shadow to hide the span element used for the ellipsis */
  box-shadow:
    40px 0 0 #fff,
    80px 0 0 #fff,
    120px 0 0 #fff,
    160px 0 0 #fff;
  /**/
  color: #8e8f8f;
  font-size: 10px;
  background: #fff; /* white background to cover the text behind */
  margin-left:2px;
}

/* this will replace the ellipsis */
.main-text span {
  position: absolute;
  /* position at the bottom right */
  top: 1.2em; /* height of one line */
  right: 0;
  padding: 0 3px;
  background: #fff; /* white background to cover the text behind */
}

.main-text span:before {
  content: "..."; /* the dots*/
}

/* the text after the dots */
.main-text span:after {
  content: "123 T.";
  color: #8e8f8f;
  font-size: 10px;

<div class="container">
  <div class="main-text">
    Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nam metus mi, dapibus sit amet posuere eu, porttitor condimentum nulla. Donec convallis lorem justo, eget malesuada lorem tempor vitae. Aliquam sollicitudin lacus ipsum, at tincidunt ante condimentum
    vitae. <span></span>
  </div>
</div>

<div class="container">
  <div class="main-text">
    Lorem ipsum <span></span>
  </div>
</div>

<div class="container">
  <div class="main-text">
    Lo <span></span>
  </div>
</div>

<div class="container">
  <div class="main-text">
    Lorem ipsum dolor sit ameta, adipiscing elit. Nam metus <span></span>
  </div>
</div>

<div class="container">
  <div class="main-text">
    Lorem ipsum dolor sit ameta, adipiscing elit <span></span>
  </div>
</div>

或者如果您希望文本仅以点显示，则如下所示：

.container {
  max-width: 200px;
  margin: 5px;
}

.main-text {
  line-height: 1.2em; /* the height of a line */
  max-height: calc(2 * 1.2em); /* restrict the height to 2 lines*/
  overflow: hidden;
  display: inline-block;
  position: relative;
}

.main-text:after {
  content: "."; /* at least one character to set the height */
  display:inline-block;
  width:40px;
  position:relative;
  z-index:999;
  /* a big box-shadow to hide the span element used for the ellipsis */
  box-shadow:
    40px 0 0 #fff,
    80px 0 0 #fff,
    120px 0 0 #fff,
    160px 0 0 #fff;
  /**/
  color: transparent; /* no colorataion*/
  font-size: 10px;
  background: #fff; /* white background to cover the text behind */
  margin-left:2px;
}

/* this will replace the ellipsis */
.main-text span {
  position: absolute;
  /* position at the bottom right */
  top: 1.2em; /* height of one line */
  right: 0;
  padding: 0 3px;
  background: #fff; /* white background to cover the text behind */
}

.main-text span:before {
  content: "..."; /* the dots*/
}

/* the text after the dots */
.main-text span:after {
  content: "123 T.";
  color: #8e8f8f;
  font-size: 10px;

<div class="container">
  <div class="main-text">
    Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nam metus mi, dapibus sit amet posuere eu, porttitor condimentum nulla. Donec convallis lorem justo, eget malesuada lorem tempor vitae. Aliquam sollicitudin lacus ipsum, at tincidunt ante condimentum
    vitae. <span></span>
  </div>
</div>

<div class="container">
  <div class="main-text">
    Lorem ipsum <span></span>
