Clip/Crop background-image with CSS

I have this HTML:

<div id="graphic">lorem ipsum</div>

with this CSS:

#graphic { background-image: url(image.jpg); width: 200px; height: 100px;}

The background image I'm applying is 200x100 px, but I only want to display a cropped portion of the background image of 200x50 px.

background-clip does not appear to be the right CSS property for this. What can I use instead?

background-position should not be used, because I'm using the above CSS in a sprite context where the image part I want to show is smaller than the element on which the CSS is defined.

may be you can write like this:

#graphic {
background-image: url(image.jpg);
background-position: 0 -50px;
width: 200px;
height: 100px;
}

You can put the graphic in a pseudo-element with its own dimensional context:

#graphic {
position: relative;
width: 200px;
height: 100px;
}
#graphic::before {
position: absolute;
content: '';
z-index: -1;
width: 200px;
height: 50px;
background-image: url(image.jpg);
}


#graphic {
width: 200px;
height: 100px;
position: relative;
}
#graphic::before {
content: '';
    

position: absolute;
width: 200px;
height: 50px;
z-index: -1;
    

background-image: url(http://placehold.it/500x500/); /* Image is 500px by 500px, but only 200px by 50px is showing. */
}
<div id="graphic">lorem ipsum</div>

Browser support is good, but if you need to support IE8, use a single colon :before. IE has no support for either syntax in versions prior to that.

Another option is to use linear-gradient() to cover up the edges of your image. Note that this is a stupid solution, so I'm not going to put much effort into explaining it...

.flair {
min-width: 50px; /* width larger than sprite */
text-indent: 60px;
height: 25px;
display: inline-block;
background:
linear-gradient(#F00, #F00) 50px 0/999px 1px repeat-y,
url('https://championmains.github.io/dynamicflairs/riven/spritesheet.png') #F00;
}


.flair-classic {
background-position: 50px 0, 0 -25px;
}


.flair-r2 {
background-position: 50px 0, -50px -175px;
}


.flair-smite {
text-indent: 35px;
background-position: 25px 0, -50px -25px;
}
<img src="https://championmains.github.io/dynamicflairs/riven/spritesheet.png" alt="spritesheet" /><br />
<br />
<span class="flair flair-classic">classic sprite</span><br /><br />
<span class="flair flair-r2">r2 sprite</span><br /><br />
<span class="flair flair-smite">smite sprite</span><br /><br />

I'm using this method on this page: https://championmains.github.io/dynamicflairs/riven/ and can't use ::before or ::after elements because I'm already using them for another hack.
