You could do this:

    .box {
        position: relative;
        width: 500px;
    }
    .border {
        position: aboslute;
        background: #ccc;
        left: 100px;
        bottom: 0;
        width: 300px;
        height: 1px;
    }

    <div class="box">
        <div class="border">
        
        </div>
    </div>

But there are infinite possibilities. Some are more semantically correct than others; this solution is simply a quick fix.

    width: 50%;

Can you throw an <hr> at the bottom of your box?
```
<div class="box">
    ...
    <hr>
</div>

.box{
    width:500px;
}

.box hr{
    width: 300px;
    border-bottom: 1px solid #ccc;
}
```

.box {
    padding-bottom: 10px;
    background-image: linear-gradient(#ccc,#ccc);
    background-size: 50% 2px;
    background-position: bottom left;
    background-repeat: no-repeat;
}

You can Use ::after or ::before pseudo-selectors. Like:

<div> something here </div>

CSS:

div {
    width: 500px;
    height: 100px;
    position: relative;
    padding-top: 20px;
    margin-top: 50px;
}

div::before {
    content: '';
    display: block;
    position: absolute;
    top: 0;
    width: 50%;
    left: 25%;
    border-top: 1px solid red;
}

Here is the jsfiddle

I would suggest doing something like this, works well in Firefox

<style type="text/css">

.box{

    width: 500px;

    height: 20px;

}

.boxHalfWidth{

    width: 250px;

    height: 1px;

    border-bottom: 1px solid #CCC;

}

</style>

</head>

<body>

<div class="box">

some data

<div class="boxHalfWidth"></div>

</div>

</body>
