我正在使用 Nivo 滑块,但想在滑块上放置一个 PNG 图像,以便它只显示透明的部分.使用 JavaScript 或 CSS 执行此操作的最佳方法是什么?
I'm using Nivo slider, but want to place a PNG image over the slider so it only shows through the parts that are transparent. What would be the best way to do this using JavaScript or CSS?
使用下面的代码更改演示,看看如何做到这一点.有很多方法可以做到这一点,因此您应该找出最适合您的情况的方法.下面的代码将滑块和另一个相对放置的图像包装在同一个 div 内.使用一点 CSS 来定位图像,您可以看到效果.
Change the demo using the code below to see how this can be done. There are a lot of ways to do this so you should figure out what works best for your situation. The code below wraps the slider and another relatively placed image inside of the same div. A bit of CSS is used to position the the image and you can see the effect in action.
HTML
<div id="outer-wrapper">
<div id="slider" class="nivoSlider">
<img src="images/toystory.jpg" alt="" />
<a href="http://dev7studios.com"><img src="images/up.jpg" alt="" title="This is an example of a caption" /></a>
<img src="images/walle.jpg" alt="" />
<img src="images/nemo.jpg" alt="" title="#htmlcaption" />
</div>
<div id="slider-mask"></div>
</div>
CSS
#outer-wrapper {
