问题:

Right now, I have 3 divs Content1, Content2, Content3

I want to add a simple stylized rule to separate the content in each. Here is the code that I am working with.

HTML

     <div id="Content1">
     <p><strong>Content1</strong></p>
     </div>

     <div id="Content2">
     <p><strong>Content2</strong></p>
     </div>

     <div id="Content3">
     <p><strong>Content3</strong></p>
     </div>

I want to add a Horizontal Rule inbetween Content1 and Content2 and between Content2 and Content3.

I have included an image so you can see exactly what I mean.

Thanks!

Don't use <hr> for this, as it's chiefly a semantic element rather than presentational. A bottom border is ideal for this. E.g. http://codepen.io/pageaffairs/pen/pjbkA

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">

<style media="all">

div {width: 500px; padding-bottom: 10px; }
#Content1, #Content2 {border-bottom: 3px solid #4588ba; margin-bottom:10px;}
div p {background: #4588ba; line-height: 150px; font-size: 2em; font-family: sans-serif; color: white; margin: 0; padding-left: 30px;}

</style>

</head>
<body>

     <div id="Content1">
     <p><strong>Content1</strong></p>
     </div>

     <div id="Content2">
     <p><strong>Content2</strong></p>
     </div>

     <div id="Content3">
     <p><strong>Content3</strong></p>
     </div>

</body>
</html>

You can use an hr tag to separate your div elements

<div id="Content1">
     <p><strong>Content1</strong></p>
</div>
<hr />
     <div id="Content2">
     <p><strong>Content2</strong></p>
</div>
<hr />
<div id="Content3">
     <p><strong>Content3</strong></p>
</div>

Demo

You can reset the default 3d style of an hr tag using solid border

hr {
    margin: 20px 0;
    border: 1px solid #f00;
}

回答3:

if you don't want to use hr tag. you can bound every div with another div and decorate it. Like this: See demo at : jsfiddle

<div id="Content1" class="divOutside">
    <div class="divInside">
        <strong>Content1</strong>       
    </div>
</div>
<div id="Content2" class="divOutside">
    <div class="divInside">
       <strong>Content2</strong>        
    </div>
</div>
<div id="Content3" class="divOutside last">
    <div class="divInside">
       <strong>Content3</strong>     
    </div>
</div>

And the Css:

.divOutside {
    border-bottom:2px blue solid;
    width:200px;
    padding-bottom:5px;
    padding-top:5px;
}
.divInside {
    width:200px;
    height:80px;
    color:#fff;
    background-color:blue;
}
.last {
    border-bottom:0;
}
