我试图让文本出现在包含背景图像的 div 元素之后，但它下面没有出现任何文本。我不确定要添加什么，该段落不存在，并且我已经为“这是一个测试”尝试了多种样式。
<div id="opener">
<p id="introText">
Adam Ginther is a<class id="blueText"> front-end developer</class> with an interest in responsive & mobile design
</p>
</div>
<br>
<div id="bottomOpener">
<p id="awesome">
I'm also 100% awesome
</p>
</div>
<p> This is a test</p>
