如何制作CSS水平导航菜单?

发布于 2024-10-15 16:55:50 字数 4511 浏览 4 评论 0原文

我需要根据以下样式进行CSS导航:

DESIRED LOOK

在此处输入图像描述

以下是我所做的设计:-

1) 附件 A - 使用精灵制作

输入图像描述这里

注意:忽略菜单项的排列

优点: 效果很好并且具有所需的外观

缺点: 如果需要的话添加另一个菜单项,必须为该特定菜单项手动制作另一个图像。 IE。不可扩展

2) 附件 B

在此处输入图像描述

优点:非常可扩展。如果必须添加另一个菜单项,则不需要制作新的额外图像。只需要在 html 代码中输入菜单名称即可。

缺点:悬停效果与所需的外观不同。

我的要求

是使用附件B以及附件A的悬停效果,但无需添加创建菜单项时的额外图像(这就是图 A 中发生的情况,尽管它具有所需的悬停效果)。

我的方法:

  1. 开始使用附件B
  2. 对于单个菜单项的悬停效果,使用 3 个图像

a) 最左边 最左边

b) 中间区域的重复切片 repeating中间区域的切片

c) 最右边缘 最右边缘

这是正确的吗?

这可能吗?

有更好的办法吗?一个教程的链接就可以了。

谢谢

background-position: left top;
}

#navigation ul li#active a {
color:#363636;
background: url(images/navigation-hover.png) repeat-x left top;
}

I need to make a css navigation according to the following style:

DESIRED LOOK

enter image description here

Below are the designs that I have done:-

1)Exhibit A - made using sprites

enter image description here

Note: Ignore the arrangement of the menu items

Pros: works well and has the desired look

Cons: if there is a need to add another menu item, another image must be manually made for that particular menu item. ie. not extensible

2)Exhibit B

enter image description here

Pros: very extensible. If another menu item must be added, new extra images need not be made. Only the menu name need to be typed in the html code.

Cons: the hover effect is not the same as the desired look.

My Requirement

Is to use Exhibit B, along with the hover effect from Exhibit A, but without having to add extra images when a menu item is created(this is what happens in Exhibit A, although it has the desired hover effect).

My approach:

  1. Start working with Exhibit B
  2. For the hover effect in the case of a single menu item use 3 images

a)left most edge left most edge

b)repeating slice of the middle area repeating slice of the middle area

c)right most edge right most edge

Is this correct ?

Is this possible ?

Is there a better way? A link to a tute would be fine.

Thanks

好吧,从技术上讲,您只需要两个精灵,一个宽的左侧+选项卡主体和一个右侧。我所说的宽度,是指 400 像素或某个您预计不会碰到的任意宽度尺寸。您用 1 kb 来换取易用性。您可以通过使用如下标记来实现此目的:

<ul class="list">
    <li><a href="#">Text</a></li>
</ul>

使用 css like:

ul.list
{
    list-style-type: none;
    margin: 0;
}
ul.list li 
{
    float: left;
    background: url(leftpluswide.png) top left no-repeat;
}
ul.list li a
{
    background: url(right.png) top right no-repeat;
}

唯一需要注意的是,由于 right.png 将与 li 上的背景重叠,因此您需要确保它没有任何透明度。

另外,为了完整起见,您可能需要对 li 和 a 应用高度(这可能需要使用 display:inline-block 或 line-height 来获取)以使所有内容都对齐。

Well you technically only need two sprites, a wide left + body of the tab and a right side. By wide, I mean, 400px or some arbitrarily wide size that you don't anticipate hitting. You're trading a kb for easy of use. You can accomplish this by having markup like:

<ul class="list">
    <li><a href="#">Text</a></li>
</ul>

with css like:

ul.list
{
    list-style-type: none;
    margin: 0;
}
ul.list li 
{
    float: left;
    background: url(leftpluswide.png) top left no-repeat;
}
ul.list li a
{
    background: url(right.png) top right no-repeat;
}

The only caveat is that since the right.png will be overlapping the background on the li, you'll need to make sure that it doesn't have any transparency.

Also for completeness sake, you might need to apply a height to the li and the a (which will potentially require a display:inline-block or a line-height to take it) to make everything line up well.
