How to crop not stretch a background-image - html

Question

I want to use a background image to my section element with width:100% and height:40%.
So i used CSS3 and used this solution:
background-image: url(My_Local_Image);
background-repeat: no-repeat;
background-size: 100% 40%;
background-position: center top;
It worked nice!
My problem now is that i want the background-image to be cropped to fit the size i specify. Now image is streched to fit.
Is there ant way that i can achieve this?

Answer 1

Unfortunately you cannot do something like
background-size: cover 40%;
cause you'll loose the 100%
the solution would be so make a separate image container, and after it an element for your (I suppose) text, setting simply background-size: cover; for the image container,
setting also width: 100%; and height : 40%; for the same.
But what you can do is

<section>
<div class="sectionImage" id="first"></div>
<div class="sectionContent">1</div>
</section>
<section>
<div class="sectionImage" id="second"></div>
<div class="sectionContent">2</div>
</section>
<section>
<div class="sectionImage" id="third"></div>
<div class="sectionContent">3</div>
</section>
section{
background:#444;
position:relative;
margin:10px auto;
height:300px;
width:800px;
color:#fff;
}
.sectionImage{
width: 100%;
height:30%;
background: transparent none no-repeat center center;
background-size: cover;
}
.sectionContent{}
#first{
background-image: url('1.jpg');
}
#second{
background-image: url(2.jpg);
}
#third{
background-image: url(3.jpg);
}

Answer 2

If I understand what you're trying to do, simply remove the 40% from your background-size and the image will fill the div at the 800x300px size.

Answer 3

You must place the background container inside your main container. After that you must provide width and height of main containter and make overflow:hidden.
You can then play with main container's width and height to change crop size. (You can use width:40%; and height:100% too)
Here is JSFidde.
HTML:
<section id="first">
<div id="bg"></div>
</section>
CSS:
#first{
height:300px;
width:200px;
overflow:hidden;
}
#bg{
background-image: url('https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcQOhLJod_xPxdgo339zfIJipPzOUZg9BunbT-ftIgDMiu2HLi0o');
background-repeat: no-repeat;
background-size: 100% 100%;
background-position: center top;
width:800px;
height:300px;
}

Answer 4

Use an inner div to get the crop effect:
Fiddle
CSS
#first{
height:300px;
width:800px;
}
#first div{
width:100%;
height:40%;
background-image: url('https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcQOhLJod_xPxdgo339zfIJipPzOUZg9BunbT-ftIgDMiu2HLi0o');
background-repeat: no-repeat;
background-size:100%;
background-position: 50% 50%;
}

Answer 5

Use the :before pseudo class
#first:before {
content: '';
position: absolute;
top: 0px;
left: 0px;
width: 100%;
height: 40%;
background-image: url(image.jpg);
background-repeat: no-repeat;
background-position: center center;
}
This will give you many CSS options to deal with both bigger/smaller images, stretching/cropping, etc., without messing with the html
