获取标题以与页面顶部对齐 [英] Get header to align with top of page

问题描述

我刚刚开始构建这个网站时遇到了这个奇怪的问题。我想让页眉与页面顶部完全齐平。但由于某种原因，有一个小的空间，大约20px高，不管我尝试什么都不会消失。我假设只有一些关于CSS和html的东西，我没有得到，所以你们能帮我一下吗？

I'm having this weird problem with this website I just started building. I want to get the header to align completely flush with the top of the page. But for some reason, there's a small space, about 20px high, that won't go away no matter what I try. I'm assuming there's just something about CSS and html that I'm not getting so can you guys help me out?

CSS ：

#header {
    background-color:#3429C9;
    /*-webkit-border-radius:15px;
    -moz-border-radius:15px;
    border-radius:15px;*/
    display:block;
    position:relative;
    z-index:2;
    margin-top:-20px;
    border-bottom:2px solid white;
    margin-bottom:20px;
    height:60px;
}

body {
    text-align:center;
    font-family: Georgia, Serif;
    background: #000000;
    margin:0;
    height:100px;
    display:block;
    border:2px solid red;
}

推荐答案

，IE）有一个默认的CSS，它给出了元素的默认样式。它也提供了一些默认的边距/填充，所以通常在开始网站设计时，应该使用 css重置文件来重置所有默认样式。

Every browser (firefox,chrome,IE) have a default CSS it comes with which give default styling to elements. It also gives some default margin/padding, so usually when starting a web site design you should use a css reset file to reset all default styling.

这样您就可以在所有浏览器中获得相同的基本行为。

That way you get the same basic behaviour for all browsers.

要快速解决yuor问题，只需将标题填充/页边距设置为0即可。

For a quick solution to yuor problem, just set the header padding/margin to 0.
