javascript - How to create a responsive image that also scales up in Bootstrap 3

Question

I am currently using twitter bootstrap 3 and I am facing a problem to create a responsive image. I have used img-responsive class. But the image size is not scaling up. If I use width:100% instead of max-width:100% then it works perfectly. Where is the problem? This is my code:

    <div class="col-md-4 col-sm-4 col-xs-12 ">
        <div class="product">               
                <div class="product-img ">
                   <img class="img-responsive" src="img/show1.png" alt="" />
                </div>
             </div>
     </div>

Answer 1

Bootstrap's responsive image class sets max-width to 100%. This limits its size, but does not force it to stretch to fill parent elements larger than the image itself. You'd have to use the width attribute to force upscaling.
