html+css3+jquery全屏页面跟随导航切换滚动
1、新建html文档。

2、书写hmtl代码。
<div class="nav">
<ul>
<li class='bg'>首页0</li>
<li>首页1</li>
<li>首页2</li>
<li>首页3</li>
<li>首页4</li>
</ul>
</div>
<div class="containter">
<div class="page current">0</div>
<div class="page page1">1</div>
<div class="page page2">2</div>
<div class="page page3">3</div>
<div class="page page4">4</div>
</div>
<div class="dian">
<ul>
<li class='da'>1</li>
<li>2</li>
<li>3</li>
<li>4</li>
<li>5</li>
</ul>
</div>

3、书写css代码。
<style>
* { margin: 0; padding: 0; list-style: none; }
a { text-decoration: none; color: #fff; }
.page { width: 100%; height: 100%; background: pink; }
.page1 { background: orange; }
.page2 { background: yellow; }
.page3 { background: green; }
.page4 { background: cyan; }
.containter { width: 100%; height: 100%; position: absolute; left: 0; top: 0; }
body, html { height: 100%; overflow: hidden; }
.dian { position: absolute; right: 20px; top: 50%; text-align: center; }
.dian ul { text-align: center; width: 14px; }
.dian li { width: 10px; height: 10px; border-radius: 50%; background: #fff; text-align: center; margin: 0 auto; margin-bottom: 10px; cursor: pointer; }
.dian .da { width: 14px; height: 14px; }
.nav { width: 100%; height: 100px; background: purple; position: absolute; left: 0; top: 0; z-index: 111; }
.nav li { float: left; width: 100px; height: 30px; margin: 35px 30px; background: black; cursor: pointer; border-radius: 5px; text-align: center; line-height: 30px; color: #fff; }
.nav li a { width: 100px; height: 30px; display: block; }
.nav .bg { background: yellow; color: #000; }
</style>

4、书写并添加js代码。
<script src="js/jquery-1.11.2.min.js"></script>
<script src="js/jquery.mousewheel.min.js"></script>
<script>
$(function() {
var nowpage=0;
var lock=true;
function donghua(){
$('.containter').animate({'top': -100*nowpage+'%'}, 500);
$('.page').eq(nowpage).addClass('current').siblings().removeClass('current');
$('.dian ul li').eq(nowpage).addClass('da').siblings().removeClass('da');
$('.nav ul li').eq(nowpage).addClass('bg').siblings().removeClass('bg');
}
$(document).mousewheel(function (event,delta) {
if(lock){
nowpage=nowpage-delta;
if(nowpage<0){nowpage=0;}
if(nowpage>4){nowpage=4;}
donghua();
lock=false;
setTimeout(function () {
lock=true;
},1000);
}
})
$('.nav ul li').click(function(event) {
nowpage=$(this).index();
if(nowpage<=4){donghua();}
});
$('.dian ul li').click(function(event) {
nowpage=$(this).index();
donghua();
});
});
</script>

5、代码整体结构。

6、查看效果。
