# CSS 工具类

# 长文本处理

# 单行文本超出显示省略号

.ellipses{
  overflow: hidden;
  white-space: nowrap;
  text-overflow: ellipsis;
}

更多场景: Handling Long Words and URLs (Forcing Breaks, Hyphenation, Ellipsis, etc) (opens new window)

# 多行文本超出显示省略号

.text-ellipsis-multi {
  overflow: hidden;
  display: -webkit-box;
  -webkit-box-orient: vertical;
  -webkit-line-clamp: 2; /* 两行 */
}

兼容性比较差。建议用 JS 库来做。

# 单词强制换行

.word-break {
  word-wrap: break-word;
  word-break: break-all;
}

父元素如果有设置 white-space: nowrap ，子元素要换行，必须要设置： white-space: normal。

# 用阴影来突出区块

.box {
  box-shadow: 0 3px 12px 0 rgba(0,0,0,.12), 0 1px 2px 0 rgba(0,0,0,.08);
}

# 文字两端对其

.t-ly-j {
  text-align: justify;
}
.t-ly-j:after {
  content: "";
  display: inline-block;
  width: 100%;
  height: 0;
}

# 禁止选中文本

.text-no-select {
  user-select:none;
}
