响应式布局的相册效果

<style> <!-- p {text-indent:2em; line-height:24px; font-size:14px} h1, img {margin:0.6em 0} h1 {font-size:16px; line-height:22px} --> </style> 响应式布局的相册效果，效果如下图所示，或者看看demo，记得调整浏览器宽度哟，或者直接下载。

开始制作吧，先来html

<ul class="pic">
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
	<li title="小猫小猫"><a href="#"><img src="images/cat.jpg" /></li>
</ul>

整体设置

*{
	padding: 0;
	margin:0;
}
.pic{
	width:98%;
	margin: 0 auto;
}
.pic:after{
	clear:both;
}

列表项实现

calc()设置列表项宽度，实现宽度等分。

.pic li{
	list-style: none;
	overflow: hidden;
	float: left;
	width: 16.6666667%; /* Fallback */
	width: -webkit-calc(100% / 6);
	width: calc(100% / 6);
	position: relative;
	z-index: 2;
}

:after伪对象选择器实现激活时的提示文本和背景。

.pic li:after{
	content: attr(title);
	display: table-cell;
	width: 90%;
	height: 94%;
	text-align: center;
	color: #fff;
	font-size:30px;
	background-color: rgba(71, 163, 218, 0.2);
	opacity:0;
	box-shadow: 1px 1px 2px rgba(255,255,255,.3);
	position: absolute;
	left: 5%;
	top: 3%;
	cursor: pointer;
	z-index: 30;

	-webkit-transform: scale(.2);
	-moz-transform: scale(.2);
	-ms-transform: scale(.2);
	-o-transform: scale(.2);
	transform: scale(.2);

	-webkit-transition: all .5s ease;
	-moz-transition: all .5s ease;
	-ms-transition: all .5s ease;
	-o-transition: all .5s ease;
	transition: all .5s ease;
}
.pic li:hover:after{
	opacity: 1;
	-webkit-transform: scale(1);
	-moz-transform: scale(1);
	-ms-transform: scale(1);
	-o-transform: scale(1);
	transform: scale(1);
}

图像的设置。

.pic li a,
.pic li a img {
	display: block;
	width: 100%;
	cursor: pointer;
}
.pic li img{
	position: relative;
	z-index: 4;
	-webkit-transform: scale(1);
	-moz-transform: scale(1);
	-ms-transform: scale(1);
	-o-transform: scale(1);
	transform: scale(1);

	-webkit-transition: all .5s ease;
	-moz-transition: all .5s ease;
	-ms-transition: all .5s ease;
	-o-transition: all .5s ease;
	transition: all .5s ease;
}
.pic li:hover img{
	-webkit-transform: scale(1.5);
	-moz-transform: scale(1.5);
	-ms-transform: scale(1.5);
	-o-transform: scale(1.5);
	transform: scale(1.5);
}

响应式布局

通过CSS3 Media Query实现响应式Web设计

@media screen and (max-width: 1190px){
	.pic li{
		width: 20%; /* Fallback */
		width: -webkit-calc(100% / 5);
		width: calc(100% / 5);
	}
}
@media screen and (max-width: 945px){
	.pic li{
		width: 25%; /* Fallback */
		width: -webkit-calc(100% / 4);
		width: calc(100% / 4);
	}
}
@media screen and (max-width: 660px){
	.pic li{
		width: 33.333%; /* Fallback */
		width: -webkit-calc(100% / 3);
		width: calc(100% / 3);
	}
}
@media screen and (max-width: 400px){
	.pic li{
		width: 50%; /* Fallback */
		width: -webkit-calc(100% / 2);
		width: calc(100% / 2);
	}
}
@media screen and (max-width: 300px){
	.pic li{
		width: 100%;
	}
}

完工！主要学习响应式布局的实现和calc的应用。
