所以如果你有：

 < div id =containerIntro> 
< h1>标题< / h1> 
< p>这里的文字就在...之后...< / p> 
< / div> 
 

您的CSS应该看起来像这样：

  #containerIntro h1，
 #containerIntro p {
 display：inline; 
 vertical-align：top; 
 font-family：'Open Sans'，sans-serif; 
 font-size：16px; 
 line-height：28px; 
}

I'm trying to place some text inside the P tag after the closing H1 tag like this:

Headline And here are the text right after....

But I can't get it to work. I made this CSS, but something is perhaps missing?

CSS:

p.start {
    font-family: 'Open Sans', sans-serif;
    font-size: 16px;
    line-height: 28px;
    text-align: justify;
    display: inline;
}

h1.start {
    font-family: 'Open Sans', sans-serif;
    font-size: 16px;
    line-height: 28px;
    margin: 0;
    display: inline-block;
}

HTML:

<div id="containerIntro">
    <h1 class="start">Headline </h1>
    <p class="start">Text......</p>
</div>

So if you had:

<div id="containerIntro">
<h1>Headline</h1>
<p>And here the text right after...</p>
</div>

Your CSS would have to look something like this:

#containerIntro h1,
#containerIntro p {
    display: inline;
    vertical-align: top;
    font-family: 'Open Sans', sans-serif;
    font-size: 16px;
    line-height: 28px;
}
