我已经按照https://www.webdesignerdepot.com/2012/10/creating-a-modal-window-with-html5-and-css3/的详细说明创建了模态。
我已经做了所有计划，但是当我单击navBar箭头链接中的模态时，它会打开，说明找不到#openModal。
随附了我的HTML和CSS代码：
body { /* General Body Properties */

<h2>Modal Box</h2>
<p>This is a sample modal box that can be created using the powers of CSS3.</p>
<p>You could do a lot of things here like have a pop-up ad that shows when your website loads, or create a login/register form for users.</p>
