今天,我想与大家分享一些专门为网格布局的图像制作的很酷的 CSS 加载动画效果。您可以把这些效果用在你的作品集,博客或任何你想要的网页中。设置很简单。我们使用了下面这些工具库来实现这个效果:
- Normalize.css 来替代传统的 CSS 复位;
- ZURB Foundation 创建具有响应式的网格;
- Masonry 创建一个动态的网格布局;
- imagesLoaded 检查是否已加载图像;
- Infinite Scroll加载更多图片并追加到画廊。
现在,让我们来看看一些实际的代码,这应该是大家最想知道的!
HTML 代码
其实 HTML 代码都是很简单的,复杂和创意的部分在 CSS。代码如下:
<div class="row">
<div class="large-12 columns main">
<ul class="small-block-grid-2 medium-block-grid-3 large-block-grid-3 masonry">
<li class="masonry-item"><a target="_blank" href="#"><img src="data:images/01.jpg" alt="" /></a></li>
<li class="masonry-item"><a target="_blank" href="#"><img src="data:images/02.jpg" alt="" /></a></li>
<li class="masonry-item"><a target="_blank" href="#"><img src="data:images/03.jpg" alt="" /></a></li>
<li class="masonry-item"><a target="_blank" href="#"><img src="data:images/04.jpg" alt="" /></a></li>
<li class="masonry-item"><a target="_blank" href="#/"><img src="data:images/05.jpg" alt="" /></a></li>
<li class="masonry-item"><a target="_blank" href="#"><img src="data:images/06.jpg" alt="" /></a></li>
<li class="masonry-item"><a target="_blank" href="#"><img src="data:images/07.jpg" alt="" /></a></li>
<li class="masonry-item"><a target="_blank" href="#"><img src="data:images/08.jpg" alt="" /></a></li>
<li class="masonry-item"><a target="_blank" href="#"><img src="data:images/09.jpg" alt="" /></a></li>
<li class="masonry-item"><a target="_blank" href="#"><img src="data:images/10.jpg" alt="" /></a></li>
<li class="masonry-item"><a target="_blank" href="#"><img src="data:images/11.jpg" alt="" /></a></li>
<li class="masonry-item"><a target="_blank" href="#"><img src="data:images/12.jpg" alt="" /></a></li>
<li class="masonry-item"><a target="_blank" href="#/"><img src="data:images/13.jpg" alt="" /></a></li>
<li class="masonry-item"><a target="_blank" href="#"><img src="data:images/14.jpg" alt="" /></a></li>
<li class="masonry-item"><a target="_blank" href="#"><img src="data:images/15.jpg" alt="" /></a></li>
</ul> <ul class="pagination">
<li><a class="next" href="index-02.php">Next Page</a></li>
</ul> <div class="loading"></div>
</div><!-- End .main -->
</div><!-- End .row -->
CSS 代码
CSS 部分主要是动画效果,我们以 tada 效果为例:
@keyframes tada
{
0%
{
-webkit-transform: scale(1);
-moz-transform: scale(1);
-ms-transform: scale(1);
-o-transform: scale(1);
transform: scale(1);
} 10%,
20%
{
-webkit-transform: scale(.8) rotate(-2deg);
-moz-transform: scale(.8) rotate(-2deg);
-ms-transform: scale(.8) rotate(-2deg);
-o-transform: scale(.8) rotate(-2deg);
transform: scale(.8) rotate(-2deg);
} 30%,
50%,
70%,
90%
{
-webkit-transform: scale(1.04) rotate(2deg);
-moz-transform: scale(1.04) rotate(2deg);
-ms-transform: scale(1.04) rotate(2deg);
-o-transform: scale(1.04) rotate(2deg);
transform: scale(1.04) rotate(2deg);
} 40%,
60%,
80%
{
-webkit-transform: scale(1.04) rotate(-2deg);
-moz-transform: scale(1.04) rotate(-2deg);
-ms-transform: scale(1.04) rotate(-2deg);
-o-transform: scale(1.04) rotate(-2deg);
transform: scale(1.04) rotate(-2deg);
} 100%
{
-webkit-transform: scale(1) rotate(0);
-moz-transform: scale(1) rotate(0);
-ms-transform: scale(1) rotate(0);
-o-transform: scale(1) rotate(0);
transform: scale(1) rotate(0);
}
} .tada
{
-webkit-animation-name: tada;
-moz-animation-name: tada;
animation-name: tada;
}
jQuery
当图像被加载进来后,我们给图像添加上 CSS 效果,然后我们找到并显示该项目,最后会刷新 Masonry 布局。当用户滚动页面的时候,无限滚动插件将装载更多的图像并重复前面的步骤。代码如下:
jQuery(document)
.ready(function($) {
// Replace "tada" with an effect from the "effects.css" file.
var effect = 'animate tada'; var masonry_selector = '.masonry'; var masonry_item_selector = '.masonry-item'; // Initialize Masonry.
var $masonry = $(masonry_selector)
.masonry({
itemSelector: masonry_item_selector
}); // Find and hide the items.
var $masonry_items = $masonry
.find(masonry_item_selector)
.hide(); // Wait for the images to load.
$masonry
.imagesLoaded()
// An image has been loaded.
.progress(function(instance, image) {
// Add the effect.
var $image = $(image.img)
.addClass(effect); // Find and show the item.
var $item = $image
.parents(masonry_item_selector)
.show(); // Lay out Masonry.
$masonry
.masonry();
}); // Load more items.
$masonry
.infinitescroll({
navSelector: '.pagination',
nextSelector: '.pagination .next',
itemSelector: masonry_item_selector,
loading: {
finishedMsg: 'No more pages to load.',
img: 'images/loader.gif',
msgText: 'Loading the next page.',
selector: '.loading'
}
}, function(items, data, url) {
var $items = $(items)
.hide()
.imagesLoaded()
.progress(function(instance, image) {
var $image = $(image.img)
.addClass(effect); var $item = $image
.parents(masonry_item_selector)
.addClass('infinite-scroll-item')
.show(); $masonry
.masonry('appended', $item);
});
});
});
