asp.net - Internet Explorer 呈现问题

Question

您好，我遇到了 Internet Exploerer 渲染问题，我有一个 aspx 页面，其中有一个表格，我将其背景图像设置为 800 x 700 像素，我的表格大小为 800 x 550。但在 Internet Explorer 2 中表格正在渲染，如图所示

此页面的 html:

<

%@ Page Language="C#" MasterPageFile="~/mftpmasterpage.Master" AutoEventWireup="true" CodeBehind="Home.aspx.cs" Inherits="FtpWebInterface.Home" %>

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>

在 firefox chorome 和 safari 中，只有上面的表格被呈现，但在 IE 中，两个表格正在呈现，请任何人帮助我解决这个问题，谢谢。

Answer 1

你检查过来源了吗？它实际上是另一张 table 吗？

我的第一个想法是背景重复。你没有指定 no-repeat在样式属性中:

变化: <table align="center" border="0" style=" width:800px;height:520px;background-image:url(Images/formbg.jpg); ... >

收件人: <table align="center" border="0" style=" width:800px;height:520px;background:transparent url(Images/formbg.jpg) top left no-repeat; ... >

看看能给你带来什么。
