边框太宽,因为边距 [英] Border too wide because of margin
问题描述
我有一个内联无序列表作为导航栏在我的html。我想要一个顶部边框,当悬停在li元素上时显示。但是当我添加边距或填充以在连续元素之间留出一些空格时,边框太宽。我不想在html中添加空格。有其他方法吗?我试着放一个空的div与定义的宽度,但它没有工作。我能得到的最好的结果是与文本装饰上线,但不幸的是,我需要一个不同的颜色比黑色。这是我的代码:
I have an inline unordered list as navigation bar in my html. I wanted a top border to show up when hovering on li element. But when I add margin or padding to make some space between consecutive elements, the border is too wide. I don't want to add spaces in html. Is there any other way? I tried putting an empty div with defined width but it didn't work. The best result I could get was with text-decoration overline, but unfortunately i need a different color than black. Here's my code:
LI
{
display: inline;
font-family: Arial;
font-size: 16px;
font-weight: bold;
text-transform: uppercase;
letter-spacing: 0.2em;
padding-left: 30px;
}
LI:hover
{
border-top: 1px solid #000000;
}
和HTML
<ul>
<a href="#"><li>link 1</li></a>
<a href="#"><li>link 2</li></a>
<a href="#"><li>link 3</li></a>
<a href="#"><li>link 4</li></a>
</ul>
推荐答案
Padding扩展了元素的宽度,元素之前和之后的间距。您可能想要详细了解盒子模型。
Padding extends the width of your elements while margin creates empty spacing after and before the element. You may want to read more about Box Model.
我调整我的代码以更好地适合您的情况:
I adjusted my code to better suit your case:
HTML:
<ul>
<a href="#"><li>link 1</li></a>
<a href="#"><li>link 2</li></a>
<a href="#"><li>link 3</li></a>
<a href="#"><li>link 4</li></a>
</ul>
CSS:
ul a {
text-decoration: none !important; //Removes default underline form link
}
li {
display: inline;
font-family: Arial;
font-size: 16px;
font-weight: bold;
text-transform: uppercase;
letter-spacing: 0.2em;
padding-left: 0.2em; // Letter spacing is making borders to extend slightly more on the right. This makes borders extend similarly on the left
padding-top: 2px; //To push top border slightly higher, so that top and bottom is the same distance from your text
margin-left: 30px;
text-align: center;
border-top: 1px solid transparent; //Stops navigation from extending on :hover
}
li:hover {
border-top: 1px solid #000; //border top on :hover
}
