【斜角按钮】

效果图

//html
//斜角按钮
<a class="title_button">信号机</a>
<a class="title_button_on">POM4</a>

//css
//斜角按钮
.title_button,.title_button_on{
    position: relative;
    display: inline-block;
    margin: 0 1px;
    padding: 0 15px;
    color: white;
    font-size: 14px;
  } 
  .title_button::before{
    background: #06479e;//默认背景色
    z-index: -1;//避免背景把按钮挡住
    position: absolute;
    content: '';
    top: 0;left: 0;right: 0;bottom: 0;
    transform: skewX(27deg);
  }

  .title_button_on::before,.title_button:hover::before{
    background: #035fdb;//鼠标移过及选中背景色
    z-index: -1;//避免背景把按钮挡住
    position: absolute;
    content: '';
    top: 0;left: 0;right: 0;bottom: 0;
    transform: skewX(27deg);
  }

开始是有效果的，后来发现失效了，所以放弃了伪类的写法，改为下面写法

//html
<span class="title_button"  ><b></b><a >信号机</a></span>
<span class="title_button_on"  ><b></b><a >INOM</a></span>

//css
//斜角按钮
.title_button,.title_button_on{
    position: relative;
    display: inline-block;
    margin: 0 1px;
    padding: 0 15px;
    color: white;
    font-size: 14px;
    cursor: pointer;
    height: 23px;
  } 
  .title_button a,.title_button_on a{
    z-index: 2;
    position: relative;
  } 
  .title_button b{
    width:100%;
    display: block;
    background: #06479e;
    z-index: 1;
    position: absolute;
    top: 0;left: 0;right: 0;bottom: 0;
    transform: skewX(27deg);
  } 
  .title_button_on b,.title_button:hover b{
    background: #035fdb;
    z-index: 1;
    position: absolute;
    top: 0;left: 0;right: 0;bottom: 0;
    transform: skewX(27deg);
  }

【常用表格样式】

<table class="mytable">
                  <tr>
                    <th >控制组 </th>
                    <th >最大采样 </th>
                    <th>最大缓存空间 </th>
                    <th>所控通道</th>
                  </tr>
                <tr>
                    <td >组1</td>
                    <td>4444</td>
                    <td>5676575</td>
                    <td>89098</td>
                </tr>
                </table>

表格样式

.mytable
        {
            border-radius: 20px;
            width: 100%;
            border-collapse: collapse;
            margin: 0 auto;
            text-align: center;
        }
        .mytable td, .mytable th
        {

        }

        .mytable tr:nth-child(odd)
