css3 笔记1-20

1.

设置或检索当内容超过指定容器的边界时是否断行。

CSS3中将 <' word-wrap '> 改名为 <' overflow-wrap '>；

由于历史原因，当你使用 <' overflow-wrap '> 时，最好同时使用 <' word-wrap '> 作为备选，作向前兼容。

2、两行缩略词

.word-wrap{
     100%;
    margin: 0;
    background: #fff;
    color: #000;
    white-space: normal;
    display: -webkit-box;
    -webkit-box-orient: vertical;
    -webkit-line-clamp: 2;
    overflow: hidden;
    text-align: -webkit-auto;
    font-size: 0.2rem;
}

3、垂直布局

.user-dialog{
    border-radius: 8px;
    background-color: #f7f7f7;
    width: 60%;
    height: 88%;
    top: 6%!important;
    display: flex;//主要这个代码
    flex-direction: column;//主要代码
    .el-dialog__header{
        text-align: center;
        background-color: #fff;
        padding: 20px;
        border-radius: 8px 8px 0 0;
    }
    .el-dialog__body{
      position: relative;
      padding: 20px 20px;
      flex: 1;//主要这个代码
      display: flex;
      flex-direction: column;
      overflow:hidden;
      overflow-y:scroll;
      border:1px solid #000;
