旋转文本覆盖粘性导航栏

sticky css-transforms css html

elias · 技术社区 · 7 年前

我正在建立一个网站,它有一个粘性导航栏和一个表格。

以下是my example.html:

<!DOCTYPE html>
<html lang="en">
    <head><meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
        <link rel="stylesheet" type="text/css" href="style.css">
        <title>Funny overlay example</title>
    </head>
    <body>
        <nav class="navbar">
            <div>
                Sticky Navbar
            </div>
        </nav>
        <section>
            <div>
                <table>
                    <tr><td rowspan="8" class="cell_vert_text"><div class="rotwrap"><div class="textcon">Problematic Text</div></div></td><td class="cell_horiz_text">Ok Text</td></tr>
                    <tr><td class="cell_horiz_text">Ok Text</td></tr>
                    <tr><td class="cell_horiz_text">Ok Text</td></tr>
                    <tr><td class="cell_horiz_text">Ok Text</td></tr>
                    <tr><td class="cell_horiz_text">Ok Text</td></tr>
                    <tr><td class="cell_horiz_text">Ok Text</td></tr>
                    <tr><td class="cell_horiz_text">Ok Text</td></tr>
                    <tr><td class="cell_horiz_text">Ok Text</td></tr>
                </table>
            </div>
        </section>
    </body>
</html>

和style.css:

* {
    margin: 0;
    padding: 0;
    box-sizing: border-box;
}

.navbar {
    background: #ff0000;
    position: sticky;
    top: 0;
    width: 100%;
}

table td.cell_vert_text {
    text-align: center;
    white-space: nowrap;
    vertical-align: middle;
    width: 1.5em;
}

table td.cell_vert_text div.rotwrap div.textcon {
    transform: rotate(270deg);
    margin-left: -10em;
    margin-right: -10em;
}

我怀疑旋转对DOM结构有一些副作用,但我真的不知道发生了什么。我试图通过引入z索引属性来解决这个问题,但没有任何帮助。我不仅在寻找一种将旋转文本推到导航栏后面的解决方案,而且要清楚地解释到底发生了什么。非常感谢。

元素上的变换创建 stacking context ,因为它的父对象都不是堆栈上下文,所以它与另一个堆栈上下文navbar(位置粘性)处于同一级别。

z-index

解决方案:在导航栏上设置z索引:

.navbar {
  z-index: 1;
  background: #ff0000;
  position: sticky;
  top: 0;
  width: 100%;
}

演示

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

.container {
  height: 150px;
  overflow: auto;
}

.navbar {
  z-index: 1;
  background: #ff0000;
  position: sticky;
  top: 0;
  width: 100%;
}

table td.cell_vert_text {
  text-align: center;
  white-space: nowrap;
  vertical-align: middle;
  width: 1.5em;
}

table td.cell_vert_text div.rotwrap div.textcon {
  transform: rotate(270deg);
  margin-left: -10em;
  margin-right: -10em;
}

<div class="container">
  <nav class="navbar">
    <div>
      Sticky Navbar
    </div>
  </nav>
  <section>
    <div>
      <table>
        <tr>
          <td rowspan="8" class="cell_vert_text">
            <div class="rotwrap">
              <div class="textcon">Problematic Text</div>
            </div>
          </td>
          <td class="cell_horiz_text">Ok Text</td>
        </tr>
        <tr>
          <td class="cell_horiz_text">Ok Text</td>
        </tr>
        <tr>
          <td class="cell_horiz_text">Ok Text</td>
        </tr>
        <tr>
          <td class="cell_horiz_text">Ok Text</td>
        </tr>
        <tr>
          <td class="cell_horiz_text">Ok Text</td>
        </tr>
        <tr>
          <td class="cell_horiz_text">Ok Text</td>
        </tr>
        <tr>
          <td class="cell_horiz_text">Ok Text</td>
        </tr>
        <tr>
          <td class="cell_horiz_text">Ok Text</td>
        </tr>
      </table>
    </div>
  </section>
</div>

将导航栏规则设为正 z-index

.navbar {
 background: #ff0000;
 position: sticky;
 top: 0;
 width: 100%;
 z-index: 1
}
