按钮衬垫太大

Question

我一直试图更改CSS中的所有属性，以解决当前导航栏按钮的问题，但没有成功。

当鼠标悬停在上面时，按钮超过了导航栏背景的高度，这是不应该的

我的HTML:

            <ul class="navigation">
                <li class="current"><a href="index.html"><em class="home"/>Home</b></a></li>
                <li><a href="second.html"><em class="photos"/><b>Photos</b></a></li>
                <li><a href="projects.html"><em class="projects"/><b>Projects</b></a></li>
                <li><a href="about.html"><em class="about"/><b>About</b></a></li>
                <li><a href="contact.html"><em class="contact"/><b>Contact</b></a></li>

Answer 1

我认为问题在于Navigation/Navigation/nav_hover.png图像。您正在将repeat应用于背景图像。

请使用

.navigation li a:hover 
{
    background: url("Navigation/Navigation/nav_hover.png") **no-repeat** scroll 0 0 transparent;
    color: #00CCFF;
    padding: 11px 5px 10px;
    text-decoration: none;
}

在style.css.中

让我知道这是否解决了问题。

Answer 2

您可以调整A元素上的填充：

.navigation li a {
  padding: 2px 5px;
}

此外，您的"em"标签应该关闭。你有打开的"em"标签，但没有关闭的"/em"标签。
