z-index 分层问题

发布于 2024-11-29 22:06:58 字数 3066 浏览 0 评论 0原文

我的CSS很糟糕,请耐心等待。

三个元素:.subscribe#pictures#menu

这三个需要将 .subscribe#menu 叠加在图片之上。 css 如下(所有选择器都是正确的)。我认为只需 z-index 和定位就可以做到这一点,但是,它不起作用。

有什么明显错误的吗?谢谢。

#slideshow * {
  margin: 0;
  padding: 0;
}
#slideshow {
  position: relative;
  padding: 14px 0 15px;
  width: 926px;
  height: 335px; 
}
#slideshow #pictures { 
  background: url('images/bg.jpg');
  width: 926px;
  height: 335px;
  left: 0;
  overflow: hidden;
}
#slideshow #pictures li {
  display: block;
  position: absolute;
  top: 0;
  width: 926px;
  z-index: -1;
}
#slideshow #pictures li img {
  display: block;
  position: relative;
  bottom: 0;
}
#slideshow #menu {
  list-style-type: none;
  right: 0;
  padding-top: 290px;
  padding-right: 20px
  position:relative;
}
#slideshow #menu li {
  display: block;
  float: right;
  z-index: 3;
}
#slideshow #menu li a {
  display: block;
  font: 11px "Lucida Grande", "Verdana";
  text-decoration: none;
  padding: 7px 0 7px 28px;
  z-index: 3;
  color: #ccc;
  line-height: 14px;
  vertical-align: middle;
}
#slideshow #menu li a:hover {
  color: #fff;
}
#slideshow #menu li.current a {
  font: 15px "Georgia";
  color: #fff;
  padding: 5px 0 5px 28px;
  line-height: 18px;
}
#slideshow #pictures .subscribe {
  height: 91px;
  width: 252px;
  position: relative;
  margin-top: 100px;
  float: left;
  bottom: 0;
  z-index: 2;
  background: url('images/SubscribeButton.png');
}
#slideshow #pictures .subscribe:hover {
  background: url('images/SubscribeButton-Dark.png');
}

标记:

<div id="slideshow">    
      <ul id="pictures">
        <li style="visibility: hidden; zoom: 1; opacity: 0; "> <a class="subscribe"></a><img src="style/images/sample1.jpeg" alt="Slide 1" title="Sample 1" style="display: none; width:926px; height:335px "></li>
        <li style="visibility: hidden; zoom: 1; opacity: 0; "><a class="subscribe"></a><img src="style/images/sample2.jpeg" alt="Buenos Aires" title="Buenos Aires" style="display: none; width:926px; height:335px "></li>
        <li style="visibility: hidden; zoom: 1; opacity: 0; "><a class="subscribe"></a><img src="style/images/Slideshow-Image1.jpg" alt="Our design team creates the perfect collections of white shirts each season" title="Creation" style="display: none; width:926px; height:335px "></li>

      </ul>

      <ul id="menu">
        <li><a href="style/images/sample1.jpeg">three</a></li>
        <li><a href="style/images/sample2.jpeg">two</a></li>
        <li><a id="first" href="style/images/Slideshow-Image1.jpg">one</a></li>

      <li class="background" style="visibility: hidden; zoom: 1; opacity: 0; left: 0px; top: 188px; width: 166px; height: 28px; "><div class="inner"></div></li></ul>
    </div>

I am terrible at css, please bear with me.

Three elements: .subscribe, #pictures, #menu.

These three need both .subscribe and #menu to be overlay on top of pictures. The css is below (all selectors are correct). I thought just z-index and positioning would do it, however, it's not working out.

Anything obviously wrong? Thank you.

#slideshow * {
  margin: 0;
  padding: 0;
}
#slideshow {
  position: relative;
  padding: 14px 0 15px;
  width: 926px;
  height: 335px; 
}
#slideshow #pictures { 
  background: url('images/bg.jpg');
  width: 926px;
  height: 335px;
  left: 0;
  overflow: hidden;
}
#slideshow #pictures li {
  display: block;
  position: absolute;
  top: 0;
  width: 926px;
  z-index: -1;
}
#slideshow #pictures li img {
  display: block;
  position: relative;
  bottom: 0;
}
#slideshow #menu {
  list-style-type: none;
  right: 0;
  padding-top: 290px;
  padding-right: 20px
  position:relative;
}
#slideshow #menu li {
  display: block;
  float: right;
  z-index: 3;
}
#slideshow #menu li a {
  display: block;
  font: 11px "Lucida Grande", "Verdana";
  text-decoration: none;
  padding: 7px 0 7px 28px;
  z-index: 3;
  color: #ccc;
  line-height: 14px;
  vertical-align: middle;
}
#slideshow #menu li a:hover {
  color: #fff;
}
#slideshow #menu li.current a {
  font: 15px "Georgia";
  color: #fff;
  padding: 5px 0 5px 28px;
  line-height: 18px;
}
#slideshow #pictures .subscribe {
  height: 91px;
  width: 252px;
  position: relative;
  margin-top: 100px;
  float: left;
  bottom: 0;
  z-index: 2;
  background: url('images/SubscribeButton.png');
}
#slideshow #pictures .subscribe:hover {
  background: url('images/SubscribeButton-Dark.png');
}

Mark-up:

<div id="slideshow">    
      <ul id="pictures">
        <li style="visibility: hidden; zoom: 1; opacity: 0; "> <a class="subscribe"></a><img src="style/images/sample1.jpeg" alt="Slide 1" title="Sample 1" style="display: none; width:926px; height:335px "></li>
        <li style="visibility: hidden; zoom: 1; opacity: 0; "><a class="subscribe"></a><img src="style/images/sample2.jpeg" alt="Buenos Aires" title="Buenos Aires" style="display: none; width:926px; height:335px "></li>
        <li style="visibility: hidden; zoom: 1; opacity: 0; "><a class="subscribe"></a><img src="style/images/Slideshow-Image1.jpg" alt="Our design team creates the perfect collections of white shirts each season" title="Creation" style="display: none; width:926px; height:335px "></li>

      </ul>

      <ul id="menu">
        <li><a href="style/images/sample1.jpeg">three</a></li>
        <li><a href="style/images/sample2.jpeg">two</a></li>
        <li><a id="first" href="style/images/Slideshow-Image1.jpg">one</a></li>

      <li class="background" style="visibility: hidden; zoom: 1; opacity: 0; left: 0px; top: 188px; width: 166px; height: 28px; "><div class="inner"></div></li></ul>
    </div>

我想你已经很接近了。但为了简单起见,我只是将 z-index 放在稍微不同的元素上(即主容器元素)。

尝试一下这里的代码: http://jsfiddle.net/irama/GwcsF/1/

关键是:

#slideshow {
    position: relative;
}

#slideshow #pictures {
    left: 0;
    z-index: 1;
    position: absolute;
}

#slideshow #menu {
    right: 0;
    position:relative;
    z-index: 3;
}

#slideshow #pictures .subscribe {
    position:absolute;
    bottom: 0;
    z-index: 2;
}

这就是您想要的吗?让我们知道你进展如何!

I think you're close. But to keep it simple, I would just put the z-index on slightly different elements (namely the main container elements).

Have a play with the code here: http://jsfiddle.net/irama/GwcsF/1/

The key bits being:

#slideshow {
    position: relative;
}

#slideshow #pictures {
    left: 0;
    z-index: 1;
    position: absolute;
}

#slideshow #menu {
    right: 0;
    position:relative;
    z-index: 3;
}

#slideshow #pictures .subscribe {
    position:absolute;
    bottom: 0;
    z-index: 2;
}

Is that roughly what you were looking for? Let us know how you go!

您需要对任何父 DIV(其中包含图像)使用 position:relative。任何覆盖该 DIV 的图层都必须嵌套在父级中,并且 CSS 属性设置为 position:absolute

这会将嵌套的 DIV 标签设置为位于其父级的左上角,并覆盖它。那么 z-index 应该可以工作。

希望有帮助。

参考: http://css-tricks.com/3118-text-blocks-图像过度/

You need to use position: relative for any parent DIV (with the image in it). Any layers to overlay that DIV must be nested inside the parent and with the CSS attribute set to position: absolute.

This sets the nested DIV tag to sit at the top left of it's parent, and overlay it. Then the z-index should work.

Hope that helps.

请发布相关的 HTML!

然而,块的内容似乎正在获取z索引,但这通常不会起作用,因为“堆叠上下文”。请参阅重叠和 ZIndex

因此,根据 HTML,您可能需要在 #pictures#menu 容器上设置 z-index

Post the related HTML, please!

However, the contents of blocks appear to be getting the z-indices, but this will often not work because of the "Stacking contexts". See Overlapping And ZIndex.

So, depending on the HTML, you'll probably need to set z-index on the #pictures and #menu containers.
