单击按钮后无法正确定位元素

  • 772

我有一个菜单，点击一个按钮，向右滑动 250 像素，将主要内容移动相同的量。我无法正确处理按钮单击，因此在单击时，它也会与侧边栏一起移动 250 像素（它保持在原位）。

按钮 HTML 代码：

<button type="button" id="sidebarCollapse" class="btn btn-info toggleBtn">
    <span>☰</span>
</button>

按钮 CSS 代码：

/* кнопка схлопывания */
#sidebarCollapse {
    position: absolute;
    left: 5px;
    top: 60px;
}

在此处输入图像描述

    我在 Checkbox 的帮助下完成了这项任务。这是我的代码
