Responsive Web Design — Images

Resize the browser window to see how the image scales to fit the page.

Using The width Property

If the width property is set to a percentage and the height property is set to «auto», the image will be responsive and scale up and down:

Example

Notice that in the example above, the image can be scaled up to be larger than its original size. A better solution, in many cases, will be to use the max-width property instead.

Using The max-width Property

If the max-width property is set to 100%, the image will scale down if it has to, but never scale up to be larger than its original size:

Example

Background Images

Background images can also respond to resizing and scaling.

Here we will show three different methods:

1. If the background-size property is set to «contain», the background image will scale, and try to fit the content area. However, the image will keep its aspect ratio (the proportional relationship between the image’s width and height):

Example

div <
width: 100%;
height: 400px;
background-image: url(‘img_flowers.jpg’);
background-repeat: no-repeat;
background-size: contain;
border: 1px solid red;
>

2. If the background-size property is set to «100% 100%», the background image will stretch to cover the entire content area:

Example

div <
width: 100%;
height: 400px;
background-image: url(‘img_flowers.jpg’);
background-size: 100% 100%;
border: 1px solid red;
>

3. If the background-size property is set to «cover», the background image will scale to cover the entire content area. Notice that the «cover» value keeps the aspect ratio, and some part of the background image may be clipped:

Example

div <
width: 100%;
height: 400px;
background-image: url(‘img_flowers.jpg’);
background-size: cover;
border: 1px solid red;
>

Different Images for Different Devices

A large image can be perfect on a big computer screen, but useless on a small device. Why load a large image when you have to scale it down anyway? To reduce the load, or for any other reasons, you can use media queries to display different images on different devices.

Here is one large image and one smaller image that will be displayed on different devices:

Example

/* For width smaller than 400px: */
body background-image: url(‘img_smallflower.jpg’);
>

/* For width 400px and larger: */
@media only screen and (min-width: 400px) body <
background-image: url(‘img_flowers.jpg’);
>
>

You can use the media query min-device-width , instead of min-width , which checks the device width, instead of the browser width. Then the image will not change when you resize the browser window:

Example

/* For devices smaller than 400px: */
body background-image: url(‘img_smallflower.jpg’);
>

/* For devices 400px and larger: */
@media only screen and (min-device-width: 400px) body <
background-image: url(‘img_flowers.jpg’);
>
>

The HTML Element

The HTML element gives web developers more flexibility in specifying image resources.

The most common use of the element will be for images used in responsive designs. Instead of having one image that is scaled up or down based on the viewport width, multiple images can be designed to more nicely fill the browser viewport.

The element works similar to the and elements. You set up different sources, and the first source that fits the preferences is the one being used:

Example

Flowers

The srcset attribute is required, and defines the source of the image.

The media attribute is optional, and accepts the media queries you find in CSS @media rule.

You should also define an element for browsers that do not support the element.

CSS Styling Images

Use the border-radius property to create rounded images:

Paris

Example

Paris

Example

Thumbnail Images

Use the border property to create thumbnail images.

Paris

Example

img <
border: 1px solid #ddd;
border-radius: 4px;
padding: 5px;
width: 150px;
>

Example

img <
border: 1px solid #ddd;
border-radius: 4px;
padding: 5px;
width: 150px;
>

img:hover box-shadow: 0 0 2px 1px rgba(0, 140, 186, 0.5);
>

Paris

Responsive Images

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

Resize the browser window to see the effect:

Cinque Terre

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:

Center an Image

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

Paris

Polaroid Images / Cards

Cinque Terre

Norway

Example

div.polaroid <
width: 80%;
background-color: white;
box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19);
>

div.container text-align: center;
padding: 10px 20px;
>

Transparent Image

Image Filters

The CSS filter property adds visual effects (like blur and saturation) to an element.

Note: The filter property is not supported in Internet Explorer or Edge 12.

Example

Change the color of all images to black and white (100% gray):

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 element that closes the modal
var span = document.getElementsByClassName(«close»)[0];

// When the user clicks on (x), close the modal
span.onclick = function() <
modal.style.display = «none»;
>

Responsive Images

An image can be set to automatically resize itself to fit the size of its container.

If you want the image to scale down if it has to, but never scale up to be larger than its original size, use the w3-image class.

Example

If you want the image to scale both up and down on responsiveness, set the CSS width property to 100%:

Example

Lights

If you want to restrict a responsive image to a maximum size, use the max-width property:
