Question

I have code like this:

<div class="container">
    <img src="img_url" alt="" />
</div>​

Container’s width has set on 600px but if image is bigger, container’s width should adjust to image size.
How I should fix my css?

.container {
    margin: auto;
    margin-bottom: 30px;
    padding: 10px;
    width: 400px;
    background-color: #2a2929;
    border: 1px solid #212020;    
}

.container img {
    display: block;
    margin-left: auto;
    margin-right: auto;    
}​

Answer 1

add to the container img

width:100%;
height:auto;

that should keep the image within the container
