Format the image to fit within a div container

Question

Format the image to fit within a div container

I'm currently utilizing Bootstrap and am looking to insert some images into my div while ensuring they are all the same size (standardized).

If the images are too large (as they typically are), I want to resize them to fit within my div and crop them if needed.

Here is what I have attempted so far:

I have tried adjusting the image style using jQuery within a function:

• If the height exceeds the width, I modify the style to max-width:100% and auto for height.

• Conversely, if the width is greater than the height.

However, since I am new to jQuery, I suspect I may be making a mistake; can someone provide guidance?

Below is my jQuery code:

$(document).ready(function(){
  photoResize();
  $(window).resize(function(){
    photoResize();
  });   
});

function photoResize(){
  image_w = $('img').width();
  image_h = $('img').height();

  if(image_h > image_w)
  {
    $('img').css("max-width","100%");
    $('img').height("auto");
  } 
  else if(image_w > image_h)
  {
    $('img').css("max-height","100%");
    $('img').width("auto");         
  } 
}

The Beauty of Simplicity

Working in the CMS at my job, I frequently use a jQuery library called imgLiquid.js for creating galleries. This library allows me to transform inline images into background images within the parent div. The beauty of this method is that it enables me to achieve the desired visual effect by cropping the image and applying inline styles like background-size: cover; and

background-position: center center;

.

If you're interested, you can check out the plugin here.

To implement the plugin, all you need is:

$(".myele").imgLiquid();

Efficiency

Despite its functionality, the plugin is incredibly light, weighing in at only around 5.106 KB. This means you can use it without worrying about slowing down your page. It truly is the simplest method I've encountered for this purpose (aside from using server-side generated thumbnails - mentioned at the end).

Crafting with CSS

After thorough testing, I can confirm that this method produces excellent results. One common concern is regarding the parent divs when the plugin hides the img element - causing the parent element to lose its height reference. To easily resolve this issue, you can use the following CSS trick:

.myelement:before{
    content: "";
    padding-top: 50%;
    display: block;
}

This CSS snippet will restore the height properties to the wrapping element. By adjusting the padding-top percentage, you can control the proportions of your elements.

For a live demonstration, check out this working example.

A Word of Advice

Although technically using thumbnails would be more efficient, my recommendation of imgLiquid.js stems from the lack of control I have over the CMS's image rendering capabilities. It provides a simple solution for managing code output, especially when control is limited.

If you're looking to ensure uniform image sizes without the hassle of javascript or complicated calculations, why not simply adjust it in your CSS?

.uniqueImageContainer img{
  width:300px;
  height:300px; // or adjust to your desired height
}

It seems like you might actually want to crop all your images to a specific width and height. In that case, you'll likely need a server-side script to handle that task.

Consider where your images are sourced from - if they're easily editable, that might be the most straightforward solution. However, if they're user-generated, you'll likely need to resize or crop them on the server side during the file upload process.

Is something like this what you are looking for? This code is written in pure CSS, without any jQuery included, so it may not be suitable for your specific case.

body {
margin-top:20px
}
.col-xs-3 {
margin: 5px 0;
width: 500px;
height:120px
}
.col-xs-3 > div {
width: 100%;
height: 120px;
background-repeat: no-repeat;
background-position: center;
background-size: cover;
}
