网页设计灰色横条怎么做

 发布时间：2020-09-19 06:24:16

1、我制作网页的软件是DW CS3，为什么命令菜单下的“扩展管理”都是灰色的，无法使用呢？

去下载扩展管理器

2、如何html语言制作一个网页实现在网页中单击一个链接,出现只有关闭按钮的新窗口,并且原窗口为灰色不可用。

搜索alertbox。原理是通过点击某按钮或者连接。跳出一个div层（原先为隐藏层，点击触发后display属性改成：block），通过css将该div设置成width：100%；height：100%；z-index：100；display：none。然后，在该div层内填充你要的东西。包括右上角的叉叉。点击叉叉改变该div的display属性为none。

3、网页设计上的无序列表，图1上鼠标上的样式怎么打，那两条浅灰色的线

这个是利用背景和边框来实现的，测试代码：

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style>
.list {width:100px; padding:0; list-style:none; border:1px solid #ccc;}
.list > li {border:8px solid transparent;}
.list > li:hover {color:#fff; background:#999; border-color:#ddd #999;}
</style>
</head>
<body>
<ul class="list">
<li>Home</li>
<li>Contact Us</li>
</ul>
</body>
</html>

4、为什么网页设计我的重新取样不能用，并且是灰色的

我知道重新取样不能用是因为 重新取样是在你改变了图片尺寸之后才能使用的。 其他三个为什么不能用不太清楚

5、我在网页中插入了一段代码，但在设计视图中无法显示，是灰色的条状，怎么办？

6、网页制作 中如何将一张图片划过时变成灰色图片 div 求请教，求帮助，谢谢啦

变成灰色图片？两种逻辑，一种就是你鼠标经过的时候，图片上面的层显示出来，而这个层要弄透明的，透明的方法你可以是用滤镜也可以用png图片做背景，但是这个方法显得很复杂，还需要定位。所以不建议使用。
另一种就是有两张图片。一张是彩色的，另一张是灰色的。然后鼠标经过的时候两个图片进行切换
<img src="彩色图片路径" onmouseover="this.src='灰色图片路径'" onmouseout="this.src=‘彩色图片路径’">这样就很好搞定了。

7、设计网页，灰色的背景应该搭配什么颜色的logo？

比较暖一点的色系会对比明显一些吧，看你的背景有多深了，灰色其实很容易搭的，你去兰 龙 设计 网看一下，那里搭配的颜色就很好呀，你可以去学习一下，另外想设计logo也可以去的，

8、网页制作中我插入表格的时候为什么出现灰色

估计是你插入表格的地方或是表格的背景不小心点到了背景色，你可以试试把表格的样式增加
<table style="background:none;">
...省略
</table>
看看可以不

9、DW网站制作的时候有这样的代码 <!-- --> 它和它中间的代码都是灰色的 这是什么意思啊

注释,标识
不在网页前台显示
仅仅做完制作页面的人分辨代码用
不起任何作用
比如我某一段做的导航
我就可以写<!--以下是导航-->
用来标识 前台是看不到的
也可以把代码放进去 意思是我不确定是否删除 暂时留着 如果用到了 我把<!-- -->删掉就可以用了
