Question

我还在学习HTML和CSS，现在我正在练习导航栏。此代码显示Mozilla和Chrome的不同填充，为什么这样做？事实上，我无法弄清楚为什么真的很烦人。我要在这里分享代码。

<!doctype html>
<html>
    <head>
        <title>Practice</title>

        <style>

Answer 1

所有浏览器都拥有自己的默认css。您尝试在RESET CODE中重置该默认css，但我认为您缺少一些元素。最好试试这个重置代码：

* {
    margin: 0;
    padding: 0;
    font-size: 12px;
    line-height: 1;
    zoom: 1;
    font: inherit;
    vertical-align: baseline;
}

Answer 2

使用导航栏进行导航： - http://getbootstrap.com/examples/navbar/

您可以从http://getbootstrap.com/

下载引导程序

使用bootstrap时非常容易

此导航栏的输出在不同浏览器中有所不同，为什么会这样做？
