1. div固定在页面最下面

 <div style=" position:fixed;bottom:0;left:0;width: 100%;">

2. 将百度搜索框嵌入页面

<style type="text/css">

input.bdbtn {width: 65px;height: 28px;line-height: 28px;font: 12px \5b8b\4f53;cursor: pointer;outline: none;display: inline-block;text-align: center;color: #fff;border: none;background-color: #1a89ed;}

input.bdtext {width: 240px;padding-left: 5px;margin-left: 10px;margin-right: 10px;height: 30px;line-height: 30px;}

</style>

<div style='overflow:hidden'>

    <form onsubmit="return baiduWithHttps(this)" action="http://www.baidu.com/baidu" target="_blank">

    <input name="tn" type="hidden" value="SE_zzsearchcode_shhzc78w"> 

    <input class='bdtext' type="text"  onfocus="checkHttps" name="word"  size="30">

    <input class='bdbtn' type="submit"value="百度搜索">

    </form>

    <script src="http://s1.bdstatic.com/r/www/cache/global/js/BaiduHttps_20150714_zhanzhang.js"></script>

    <script>

        function checkHttps () {

            BaiduHttps.useHttps();    

        };

        function baiduWithHttps (formname) {

            var data = BaiduHttps.useHttps();

            if (data.s === 0) {

                return true;

            }

            else {

                formname.action = 'https://www.baidu.com/baidu' + '?ssl_s=1&ssl_c' + data.ssl_code;

                return true;

            }

        };

    </script> 

</div>
