Learn how to create responsive images with CSS

With the increase of internet-connected devices, their sizes and specifications vary.If you have ever dreamt of creating a website in the future or now, you will get to know that having responsive images on your webpages is very important.

Unresponsive images will make the website or webpage layout horizontally scrollable giving users poor experience.

If you have ever used a modern front-end framework like Materialize CSS or Bootstrap. These frameworks have classes that you have to give or add to an image to make it responsive

For example in Materialize CSS, you give an image the class of responsive-img whereas in Bootstrap you give an image the class of img-responsive in order for the image to be responsive despite the screen size

That's for frameworks, you just add a class and the image becomes responsive. But what really goes in the background it's nothing big or magic. You can also come up with a custom class and give it these properties and values shown below and later add it to any image you want to be responsive.

Making images responsive with CSS is actually very simple. Instead of applying an absolute width to an element, like this:

/*Bad Practice*/
img { width: 720px; }

Below is the right way to make images responsive:


/*Good Practice*/
img {
max-width: 100%;
display: block;
height: auto;

Now let's digest the above CSS properties and values.

The max-width property of 100% scales the image to fit the width of its container, but the image won't stretch wider than its original width.

Setting the display property to block changes the image from an inline element (which is the default) to a block element on its own line.

The height property of auto keeps the original aspect ratio of the image.

Major Points to NOTE::
  • Your img tag should have a max-width set to 100%.
  • It should have a display property set to block.
  • Lastly, it should have a height set to auto.
