To render a huge number of images in a website, it is advisable to use webp format as it provides better compression.
We use the <picture> element to provide a fallback for unsupported browsers −
<picture> <source srcset="filename.webp" type="image/webp"> <source srcset=" filename.jpg" type="image/jpeg"> <img src=" filename.jpg"> </picture>
The following examples illustrate this fallback.
Example
<!DOCTYPE html>
<html>
<head>
<style>
* {
margin: 2%;
}
</style>
</head>
<body>
<picture>
<source srcset="sky.webp">
<img src="sky.jpg" />
</picture>
</body>
</html>Output
This will produce the following result −
Example
<!DOCTYPE html>
<html>
<head>
<style>
* {
margin: 10px;
}
</style>
</head>
<body>
<picture>
<source srcset="tree.webp" type="image/webp" />
<source srcset="tree.jpg" type="image/jpeg" />
<img src="tree.jpg" />
</picture>
</body>
</html>Output
This will produce the following result −
