我有一个div使用 jquery+css 消失的。它工作得很好，但我遇到了一个问题。div下次用户在同一个 wordpress 网站上打开页面时，我如何才能让它不重新加载。因为div存在于 中header.php，所以每次调用新页面时都会如此div，即使用户之前关闭了它。
有没有办法使用现有的基础设施确保每次访问只加载一次横幅？我觉得必须有某种方法可以做到这一点，特别是因为 wordpress 是在 php 上运行的，但我有点超出我的深度。
这是我目前正在编辑的网站，这里是与横幅相关的代码。
HTML：
<div id="greenbanner">
<img src="<?php bloginfo('template_directory'); ?>/Devices.png" id="devices">
<img src="<?php bloginfo('template_directory'); ?>/bigx.png" id="bigx">
<div id="bannertext">Spundge lets you discover, <br />curate, and create better content. <br /><br />
<div id="jointhedarkside"><a style="color:#ffffff;" href="https://www.spundge.com/account/signup/">Get Started - It's Free</a></div>
</div>
</div>
查询：
$(document).ready(function(){
$("#headershadow").hide();
$("#bigx").click(function(){
$("#greenbanner").hide(1000);
$("#headershadow").show();
});
});
CSS：
