Responsive Images

Responsive images will automatically adjust to fit the size of the screen.

Resize the browser window to see the effect:

If you want an image to scale down if it has to, but never scale up to be larger than its original size, add the following:

Example

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

Center an Image

To center an image, set left and right margin to auto and make it into a block element:

Example

img {
  display: block;
  margin-left: auto;
  margin-right: auto;
  width: 50%;
}

img {
  filter: grayscale(100%);
}

Responsive Image Gallery

CSS can be used to create image galleries. This example use media queries to re-arrange the images on different screen sizes. Resize the browser window to see the effect:

Cinque Terre
Add a description of the image here
Forest
Add a description of the image here
Northern Lights
Add a description of the image here
Mountains
Add a description of the image here

Example

.responsive {
  padding: 0 6px;
  float: left;
  width: 24.99999%;
}

@media only screen and (max-width: 700px){
  .responsive {
    width: 49.99999%;
    margin: 6px 0;
  }
}

@media only screen and (max-width: 500px){
  .responsive {
    width: 100%;
  }
}

Image Modal (Advanced)

This is an example to demonstrate how CSS and JavaScript can work together.

First, use CSS to create a modal window (dialog box), and hide it by default.

Then, use a JavaScript to show the modal window and to display the image inside the modal, when a user clicks on the image:

Northern Lights, Norway

Example

// Get the modal
var modal = document.getElementById('myModal');

// Get the image and insert it inside the modal - use its "alt" text as a caption
var img = document.getElementById('myImg');
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
img.onclick = function(){
  modal.style.display = "block";
  modalImg.src = this.src;
  captionText.innerHTML = this.alt;
}

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];

// When the user clicks on <span> (x), close the modal
span.onclick = function() {
  modal.style.display = "none";
}
×

// Get the modal var modal = document.getElementById('myModal2'); var images = document.getElementById('eh'); var modalImg = document.getElementById("img01"); var captionText = document.getElementById("caption"); images.onclick = function(){ modal.style.display = "block"; modalImg.src = images.src; modalImg.alt = images.alt; captionText.innerHTML = images.alt; }
