Image to Fit Containing Div - html

Question

I have done this many times before but it doesn't seem to work now for whatever reason. I want the image to be the full the width of the container but it doesn't. Any ideas?
jsFiddle: http://jsfiddle.net/Lqffk1ak/
Code:
img {
max-width: 100%;
max-height: 100%;
}
div {
background: #ccc;
}
<div>
<img src="https://s11.postimg.org/dpgqru2pv/Police2_600x250.jpg" class="full-width">
</div>

Answer 1

Just add width:100% to img
img {
width:100%
}

Answer 2

Looking at your class, what you should add is some CSS on the full-width class to make the img width 100%.
This way, only the images set as "full-width" will be forced 100%. The other one will keep the max-width rule of 100%, but won't be resized if they are smaller.
img {
max-width: 100%;
max-height: 100%;
}
.full-width {
width: 100%;
}
div {
background: #ccc;
}
<div>
<img src="https://s11.postimg.org/dpgqru2pv/Police2_600x250.jpg" class="full-width">
</div>

Answer 3

Just make your image width 100%. Even you resize your container image will fit on it.
img{
width:100%;
}

Answer 4

You can check the updated fiddle here
Change the css :
div {
height: 100%;
}
img {
width: 100%;
min-height: 100%;
}

Answer 5

I know this isn't directly an answer to your question but generally speaking, upscaled images look quite nasty. A way people get past this is to have the image centered and then add a blurred version behind it.
Like this:
body {
margin: 0;
}
.image {
position: relative;
text-align: center;
overflow: hidden;
font-size: 0px;
}
.background-image {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-image: url('https://s11.postimg.org/dpgqru2pv/Police2_600x250.jpg');
background-size: cover;
z-index: -1;
}
.blur {
filter: blur(10px);
}
<div class="image">
<div class="background-image blur"></div>
<img src="https://s11.postimg.org/dpgqru2pv/Police2_600x250.jpg" class="full-width">
</div>
I hope you find this helpful.

Because your Image is has 600px; height, and the you have set max-width:100%. So max-width property will only work when the parent dive will be smaller then 600px;.
To make image to the containing div, you have to give set image's property 100%; that is .full-width {width: 100%;}
