我已經寫了這段代碼,所有的div都正常工作,也是導航。但是「標題」的黑色似乎不起作用。我已經發布了下面的整個代碼。請看下面的代碼。爲什麼id =「header」的黑色不顯示?
<!DOCTYPE html>
<html>
<head>
<style>
body
{
padding: 0;
}
#container
{
margin: 0 auto;
width:100%;
height: 1500px;
padding: 0px;
}
#header
{
background-color: black;
margin: 0px;
}
#logo
{
background-color: green;
}
#headTable
{
float:right;
}
#logo
{
margin: 5px 0px 5px 70px;
float: left;
width:150px;
height:100px;
}
#headTable ul
{
list-style-type: none;
margin: 0;

#headTable ul li

#nav
