我开始使用“开始使用ASP.NET 4:在C#和VB中”(Imar Spaanjaars - Wrox)这本书来学习ASP.NET。现在我被困在第79页的“试一试”部分:每件事情都是正确的,除了侧边栏没有背景颜色,预计它会变成灰色。
我的页面:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<p>

</span>to <a href="http://www.PlanetWrox.com">www.PlanetWrox.com</a>, the coolest
music community site on the Internet.</p>
<p>
Feel free to have a look around; there are lots of interesting <strong>reviews and concert

<div id="SideBar">
Sidebar Goes Here</div>
<div id="Footer">
Footer Goes Here
</div>
</div>
</form>
</body>
</html>
CSS文件:
#Header
{
background-color: #C0C0C0;
width: 844px;
height: 86px;
}
*
{
font-family: Arial;
}
h1
{
font-size: 20px;
}
#PageWrapper
{
width: 844px;
}
#MenuWrapper
{
width: 844px;
}
#MainContent
{
width: 664px;
float: left;
}
#Sidebar
{
background-color: Gray;
width: 180px;
float: left;
}
#Footer
{
background-color: #C0C0C0;
width: 844px;
clear: both;
}
结果(侧边栏背景预计为灰色):
我犯了什么错误,任何人都可以告诉我它在哪里吗?
答案 0 :(得分:5)
“补充工具栏”!=“SideBar”
区分大小写
