有多种方法可以执行此操作，请查看下面的代码段。

@import url(http://fonts.googleapis.com/css?family=Open+Sans);

body {
  padding: 20px;
  font: 1.2em/1.2em 'Open Sans', sans-serif;
}
.module {
  width: 250px;
  margin: 0 0 1em 0;
  overflow: hidden;
}
.module p {
  margin: 0;
}

.line-clamp {
  display: -webkit-box;
  -webkit-line-clamp: 3;
  -webkit-box-orient: vertical;  
}

.fade {
  position: relative;
  height: 3.6em; /* exactly three lines */
}
.fade:after {
  content: "";
  text-align: right;
  position: absolute;
  bottom: 0;
  right: 0;
  width: 70%;
  height: 1.2em;
  background: linear-gradient(to right, rgba(255, 255, 255, 0), rgba(255, 255, 255, 1) 50%);
}

.last-line {
  height: 3.6em; /* exactly three lines */
  text-overflow: -o-ellipsis-lastline;
}

.ftellipsis {
  height: 3.6em;
}

h1 {
  margin: 0 0 1em 0;
}
h2 {
  font-size: 1.2em;
}
