<code class="html"><div class="tips">
    xxxxx
</div></code>

<code class="css">.tips{
    position:fixed;
    display:block;
    bottom:0;
    left:0;
    height:100px;
    width:100%;
    background:#ccc;
    color:#fff;
    z-index:999;
}</code>

Use fixed positioning

HTML:

<code><div class="nologin">
    这个是内容
</div></code>

css

<code>.nologin{
    position:fixed; 
    bottom:0;
    left:0;
    height:100px;
    width:100%;
    background:#eee;
    color:#333;
    z-index:999;
    display:none
}</code>

Then hide and listen for scroll events. When the scroll is larger than the position you want, the prompt will be displayed, otherwise it will be hidden
