代码用文档方式给大家,直接插入到你们网站里面就行了,PC端和移动端都适用有点基础的可以改下代码让他更好看!
代码如下:
<div class="web_notice" style=" position: fixed; top: 0; left: 0; width: 100%; height: 100%; background: rgba(0,0,0,0.3); z-index: 99999; "> <div style=" position: fixed; top: 50%; left: 50%; width: 550px; background: #FFF; transform: translate(-50%, -50%); border-radius: 40px; padding: 50px 40px; "> <h3 style=" font-weight: bold; text-align: center; font-size: 30px; ">网站通知</h3> <div style=" font-size: 16px; margin-top: 26px; line-height: 30px; color: #999; ">公告</div><a style=" display: block; background: #98a3ff; color: #FFF; text-align: center; font-weight: bold; font-size: 19px; line-height: 60px; margin: 0 auto; margin-top: 45px; border-radius: 32px; width: 80%; " onclick="javascript:document.querySelector('.web_notice').remove()">我知道了</ a> </div> </div>
