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

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>

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.

I guess image is than corrupted. Example: image size is 195px X 146px.

It will work inside lower resolutions like tablets. When you have 1280 X 800 resolution it will force larger as there is also width 100 %. Maybe CSS inside media query like icons fonts is the best solution.

Not sure if it helps you still... but I had to do a small trick to make the image bigger but keeping it responsive

@media screen and (max-width: 368px) {
    img.smallResolution{
        min-height: 150px;
    }

}

Hope it helps P.S. The max width can be anything you like

I found that you can put the .col class on the image will do the trick - however this gives it extra padding along with any other attributes associated with the class such as float left, however these can be cancelled by say for example a no padding class as an addition.

Sure things!

.img-responsive is the right way to make images responsive with bootstrap 3 You can add some height rule for the picture you want to make responsive, because with responsibility, width changes along the height, fix it and there you are.

If setting a fixed width on the image is not an option, here's an alternative solution.

Having a parent div with display: table & table-layout: fixed. Then setting the image to display: table-cell and max-width to 100%. That way the image will fit to the width of its parent.

Example:

<style>
    .wrapper { float: left; clear: left; display: table; table-layout: fixed; }
    img.img-responsive { display: table-cell; max-width: 100%; }
</style>
<div class="wrapper col-md-3">
    <img class="img-responsive" src="https://www.google.co.uk/images/srpr/logo11w.png"/>
</div>

Fiddle: http://jsfiddle.net/5y62c4af/

Try the following in your CSS stylesheet:

.img-responsive{
  max-width: 100%;
  height: auto;
}

Try to do so:

1) In your index.html

<div class="col-lg-3 col-md-4 col-xs-6 thumb">
  <a class="thumbnail" href="#">
    <div class="ratio" style="background-image:url('../Images/img1.jpg')"></div>
  </a>
</div>

2) In your style.css

.ratio {
  position:relative;
  width: 100%;
  height: 0;
  padding-bottom: 50%; 
  background-repeat: no-repeat;
  background-position: center center;
  background-size: cover;  
}
