CSS:字体上边距
我知道这个问题的标题很愚蠢,但我想不出更好的答案。我已经在这个主题上搜索了几个小时,但要么我搜索到了错误的东西,要么我错过了一些 CSS 基础知识。
我有一个容器 div,其左上角放置了 40x40px 背景图像。我想将 h2 标签中的文本顶部与背景图像的顶部对齐,我尝试这样做。
HTML:
<div id="container">
<h2 id="title">Lorem</h2>
</div>
CSS:
body {
font-family: Arial, Helvetica, sans-serif;
font-size: 13px;
}
#container {
background: url('test-icon.png') top left no-repeat;
margin: 200px auto; /* To center the container on the page*/
min-height: 50px;
padding-left: 50px; /* To prevent the text from "colliding with the background-image"*/
width: 300px;
}
#title {
font-family: "Arial Black", Arial, Helvetica, sans-serif;
font-size: 1.3em;
text-transform: uppercase;
}
我使用 Eric Meyers CSS 重置来摆脱浏览器特定的样式,但在上面的代码中忽略了这一点。
我创建了一个 实时示例
问题是背景图像和文本顶部来自h2 标签未对齐 - h2 标签顶部有一个小“边距”。这个边距似乎随着字体大小的变化而变化。当我使用 Google Chromes 检查器时,它告诉我 h2 和 div 标签的边距和填充都是 0px。由于浏览器渲染字体的方式不同,我不想乱用负边距,以免破坏布局。有没有办法“安全”地消除这个余量?完全清楚的是,我想要实现的是这个。
I know the title of this question is stupid, but I couldn't come up with anything better. I have searched for hours on this topic, but either I search for something wrong, or else I have missed out on some CSS basics.
I have a container div with a 40x40px background-image placed in the top left corner. I want to align the top of the text from an h2 tag with the top of that background-image, which I have tried to do like this.
HTML:
<div id="container">
<h2 id="title">Lorem</h2>
</div>
CSS:
body {
font-family: Arial, Helvetica, sans-serif;
font-size: 13px;
}
#container {
background: url('test-icon.png') top left no-repeat;
margin: 200px auto; /* To center the container on the page*/
min-height: 50px;
padding-left: 50px; /* To prevent the text from "colliding with the background-image"*/
width: 300px;
}
#title {
font-family: "Arial Black", Arial, Helvetica, sans-serif;
font-size: 1.3em;
text-transform: uppercase;
}
I have used Eric Meyers CSS reset to get rid of browser specific styles, but have left this out in the above code.
I have created a live example
The problem is that the background-image and the top of the text from the h2-tag do not align - there is a small "margin" in the top of the h2 tag. This margin seems to change with the font size. When I use Google Chromes inspector, it tells me that the margin and padding of the h2 and div tag are all 0px. As browsers render fonts differently, I don't mant to mess around with negative margins in case it breaks the layout. Is there a way to "safely" get rid of this margin? To be totally clear, what I want to acheive is this.

我认为你的问题是
line-height
在上。稍微摆弄一下就知道你希望它是这样的:
你可能需要使用
px
作为你的font-size
以使事情在各种浏览器中一致地工作。I think your problem is the
line-height
on the<h2>
. A bit of fiddling around tells me that you want it to be:You might need to use
px
for yourfont-size
to get things to work consistently in various browsers.您是否尝试过行高:1; ?
Have you tried line-height: 1; ?
