文字正在改变HTML

标签： html css

我正在开发一个网页，我对HTML很新。 我有一个问题，我的导航栏下降到一个新的行，一切都随之跳跃。 像这样：enter image description here

enter image description here

我认为这是悬停高度的问题。我有一个项目描述另一个框与导航栏。所以应该独立。

Css代码如下：

 /* HTML5 display-role reset for older browsers */
article, aside, details, figcaption, figure, 
footer, header, hgroup, menu, nav, section {
    display: block;
}
body {
    line-height: 1;
}
ol, ul {
    list-style: none;
}
blockquote, q {
    quotes: none;
}
blockquote:before, blockquote:after,
q:before, q:after {
    content: '';
    content: none;
}
table {
    border-collapse: collapse;
    border-spacing: 0;
}

#header     {
            height:100px;
            width:1260px;
            margin-left:auto;
            margin-right:auto;
            }

#navpanel   {
            height:50px;
            width:1260px;
            background:rgba(0,50,0,1);
            border-radius: 10px;
            margin-left:auto;
            margin-right:auto;
            margin-top:50px;
            box-shadow:10px 10px 10px #888888;

            }

你走了。我做了几处改动：   我在您的.menu 3 ul添加了一个ID。

  ul class="context">
                <li>
                    <p >Planning</p>
                </li>
                <li>
                    <p >Brainstorm</p>
                </li>
            </ul>

我删除了过渡动画。它造成了太多问题。  我删除了一些不必要/有问题的CSS规则。  我用position:absolute制作了菜单并添加了一些格式。

以下是完整的 CSS

    line-height: 1;

    list-style: none;

尝试使用z-index或position: absolute;将导航标题放在实际页面上方：）
