Leveraging bootstrap for generating a grid structure with image sizes that adjust dynamically

Just dipping my toes into the world of CSS, so please be kind ;). Here's a setup I have for a grid:

<div class="row">
     <div class="col-lg-2 col-sm-3 col-xs-4">
       <a href="#" class="thumbnail">
          <img src="http://placehold.it/150x150" class="img-responsive">
       </a>
     </div>
     <div class="col-lg-2 col-sm-3 col-xs-4">
        <a href="#" class="thumbnail">
          <img src="http://placehold.it/150x150" class="img-responsive">
        </a>
     </div>
</div>

The issue arises when I replace the placeholder image with an actual one; I want it to fill the space completely regardless of size. Essentially, I'm looking for a way to maintain the 150x150 ratio no matter what. While the width (max-width: 100%) seems to work fine, the height doesn't cooperate. Tinkering with height, width, max-height, etc. hasn't yielded any results.

Answer №1

I am also a beginner in using bootstrap. I may have spent more time on this than necessary, but here is what I discovered works well:

It's best to create a custom stylesheet that loads after the bootstrap.css file. This way, you can make customized adjustments without affecting the original css. Here is an example of how you can make these adjustments:

.thumbnail-image {
    overflow: hidden;
    height: 150px; 
}

.thumbnail-image > img {
    width: 100%;
}

To implement this, simply place the image within a div with the "thumbnail-image" class in your HTML code.

<div class="row">
     <div class="col-lg-2 col-sm-3 col-xs-4">
       <a href="#" class="thumbnail">
       <div class="thumbnail-image"><img src="http://placehold.it/150x150"></div> 
       </a>
     </div>
     <div class="col-lg-2 col-sm-3 col-xs-4">
        <a href="#" class="thumbnail">
       <div class="thumbnail-image"><img src="http://placehold.it/150x150"></div> 
       </a>
     </div>
</div>

You may need to adjust the custom height property for the .thumbnail-image class as the column sizes change at different breakpoints. But aside from that, this solution should work perfectly!

Answer №2

To enhance your image display, consider including height and width attributes within the img tag as shown below:

<img src="..." height="200" width="200">

It is uncertain how this will affect bootstrap's responsive image class. The recommended approach is to use an image that already has the desired dimensions.
