The picture
element is an HTML5 element that allows you to specify multiple versions of an image for different device sizes and resolutions. This can help to improve the performance and visual quality of your website on a variety of devices.
Here’s an example of how to use the picture
element:
<!DOCTYPE html>
<html>
<head>
<title>Picture Element Example</title>
</head>
<body>
<h1>Picture Element Example</h1>
<picture>
<source media="(min-width: 800px)" srcset="large-image.jpg">
<source media="(min-width: 500px)" srcset="medium-image.jpg">
<img src="small-image.jpg" alt="A small image">
</picture>
</body>
</html>
In this example, we have three versions of an image: large-image.jpg
, medium-image.jpg
, and small-image.jpg
. The picture
element contains three child elements: two source
elements and an img
element.
The source
elements each have a media
attribute that specifies a media query. The first source
element specifies a media query for devices with a minimum width of 800 pixels, and the second source
element specifies a media query for devices with a minimum width of 500 pixels.
The srcset
attribute on each source
element specifies the image to use for that device size. For devices with a minimum width of 800 pixels, the large-image.jpg
file will be used. For devices with a minimum width of 500 pixels, the medium-image.jpg
file will be used.
Finally, the img
element specifies the image to use as a fallback for devices that do not match either of the media queries. In this case, the small-image.jpg
file will be used.
Using the picture
element in this way can help to reduce the file size of your web pages and improve the load time and performance of your website on a variety of devices.
