css javascript

Make a responsive navigation bar that can automatically change the style of the navigation bar with different screen resolutions or browser window sizes. The main thing used here is CSS3 Media Query.

It should also be mentioned that ie6-ie8 does not support CSS3 Media Query, so we need special treatment for ie6-ie8 and let them maintain the default style. This is This should be taken into consideration in layout and style.

First take a look at the layout. The html code is as follows:

<p class="navBar">
    <p class="nav">
        <ul id="menu">
            <li class="current"><a href="#">首页</a></li>
            <li><a href="#">电影</a></li>
            <li><a href="#">电视剧</a></li>
            <li><a href="#">动漫</a></li>
            <li><a href="#">综艺</a></li>
            <li><a href="#">纪录片</a></li>
            <li><a href="#">公开课</a></li>
        </ul>
        <p class="hot">
            <a href="#">钢铁侠3</a>
            <a href="#">中国合伙人</a>
            <a href="#">盛夏晚晴天</a>
            <a href="#">陆贞传奇</a>
        </p>
        <!--判断浏览器是否是IE9,IE10或者是非IE浏览器-->
        <!--[if (gt IE 8) | !(IE)]><!-->
        <h1 class="title" id="title">
            <a href="#"></a>
            <span class="btn" id="btn"></span>
        </h1>
        <!--<![endif]-->
    </p>
</p>
Copy after login

The html part also needs a conditional comment. When the browser is ie6-8, mount a class to the html tag." ie6-8", which facilitates processing in the style sheet:

<!DOCTYPE html>
<!--[if lt IE 9]><html class="ie6-8"><![endif]-->
<html>
...
Copy after login

The following is style control, first process the overall style and ie6-ie8

* {margin: 0; padding: 0;}
body {font: 14px/22px "宋体", arial, serif;}
.navBar {margin-top: 80px; width: 100%; height: 38px; background: #333;}
.nav {margin: 0 auto; border: 0px solid #ccc;}
.nav ul {list-style: none; width: auto;}
.nav ul li {height: 38px; text-align: center;}
.nav ul li a {display: block; font-size: 16px; color: #fff; text-decoration: none; line-height: 39px;}
.ie6-8 .nav {width: 1000px; height: 38px;}
.ie6-8 .nav ul li {float: left;}
.ie6-8 .nav ul li a {padding: 0 30px 0 30px;}
.ie6-8 .nav ul li.current {background: #f60;}
.ie6-8 .nav ul li:hover a {color: #f60;}
.ie6-8 .nav ul li a:hover {_color: #f60;}/*IE6 Hack*/
.ie6-8 .nav ul li.current:hover a {color: #fff;}
.ie6-8 .nav .hot {float: left; margin-left: 20px; padding-top: 8px;}
.ie6-8 .nav .hot a {padding: 0 5px 0 5px; font-size: 12px; color: #fff; text-decoration: none;}
.ie6-8 .nav .hot a:hover {color: #f60; text-decoration: underline;}
.ie6-8 .nav .title {display: none;}
Copy after login

ok, and then use Media Query.

When the screen width is greater than 1000px:

@media screen and (min-width: 1000px) {
    .nav {width: 1000px; height: 38px;}
    .nav ul li {float: left; width: auto;}
    .nav ul li a {padding: 0 30px 0 30px;}
    .nav ul li.current {background: #f60;}
    .nav ul li:hover a {color: #f60;}
    .nav ul li.current:hover a {color: #fff;}
    .nav .hot {margin-left: 20px; padding-top: 8px;}
    .nav .hot a {padding: 0 5px 0 5px; font-size: 12px; color: #fff; text-decoration: none;}
    .nav .hot a:hover {color: #f60; text-decoration: underline;}
    .nav .title {display: none;}
}
Copy after login

When the screen width is between 640px and 1000px:

@media screen and (min-width: 640px) and (max-width: 1000px) {
    .nav {width: auto; height: 38px;}
    .nav ul li {float: left; width: 14%; min-width: 50px;}
    .nav ul li.current {background: #f60;}
    .nav ul li:hover a {color: #f60;}
    .nav ul li.current:hover a {color: #fff;}
    .nav .hot {display:none;}
    .nav .title {display: none;}
}
Copy after login

When the screen width is less than 640px:

@media screen and (max-width: 640px) {
    .navBar {margin-top: 0; height: auto; background: #444;}
    .nav {width: auto; height: auto;}
    .nav ul li {margin-top: 1px; width: 100%; min-width: 100px;background: #333;}
    .nav ul li a:active {background: #f60;}
    .nav .hot {display:none;}
    .nav .title {position: relative; width: 100%; height: 38px; border-top: 1px solid #444; background: #333; text-align: center; font:normal 20px/35px "Microsoft YaHei", arial, serif; letter-spacing: 2px;}
    .nav .title a {color: #f60; text-decoration: none;}
    .nav .title .btn {position: absolute; right: 10px; top: 0; width: 34px; height: 34px; padding: 2px; background: url(btn.png) center center no-repeat; cursor: pointer;}
}
Copy after login

ok, the layout and style control is complete

Let’s take a look at js, but I won’t go into details about js. Let’s post the core code:

This part of the code is used to produce animation effects:

var move = function (obj, target) {
    var timer;
    clearInterval(timer);
    timer = setInterval(function () {
        var speed = (target - obj.offsetTop)/3;
        speed = speed > 0 ? Math.ceil(speed) : Math.floor(speed);
        if (Math.abs(obj.offsetTop - target) < 4) {
            clearInterval(timer);
            obj.style.marginTop = target + "px";
        } else {
            obj.style.marginTop = obj.offsetTop + speed + "px";
        }
    }, 30);
    }
Copy after login
