<meta charset="UTF-8"> 
<meta name="viewport" content="width=device-width, initial-scale=1.0"> 
<title>CSS Image Resize Example</title> 
<style> 
/* Define a class to control image resizing */ 
.image-container { 
width: 200px; /* Set the width of the container */ 
height: 200px; /* Set the height of the container */ 
overflow: hidden; /* Hide content that exceeds the container size */ 
} 
/* Control the size and display of the image */ 
.image-container img { 
width: 100%; /* The image width fills the container */ 
height: auto; /* Adaptive height */ 
object-fit: cover; /* Maintain proportions and fill the container */ 
} 
</style> 
</head> 
<body> 
<h1>CSS Image Resize Example</h1>

In this example, we use the .image-container class to control the image’s size. This class sets a fixed width and height and uses overflow: hidden; to hide any excess image size. The image itself uses width: 100%; and height: auto; to adjust its size within the container, and object-fit: cover; to ensure the image proportionally fills the entire container.

This approach gives developers flexible control over the display and size of https://coder-cafe.com/wp-content/uploads/2025/09/images on a web page, adapting to different layouts and needs.

Resizing https://coder-cafe.com/wp-content/uploads/2025/09/images in CSS is a common task in web design. Best practice is to use the CSS width and height properties to control the image size while maintaining its aspect ratio. This ensures that the image doesn’t appear distorted or stretched when resized.

Here is a simple example showing how to use CSS to resize an image:

<!DOCTYPE html> 
<html lang="en"> 
<head> 
<meta charset="UTF-8"> 
<meta name="viewport" content="width=device-width, initial-scale=1.0"> 
<title>Image Resize Example</title> 
<style> 
/* Set the image size to 200 pixels wide and automatically adjust the height */ 
.image { 
width: 200px; 
height: auto; 
} 
</style> 
</head> 
<body> 
<!-- The image will be resized to 200x200 pixels --> 
<img class="image" src="example.jpg" alt="Example Image"> 

</body> 

</html>

The effect of executing this code is as follows:

How to change image size in CSS

In this example, we define a CSS style with the class name image to set the image’s width to 200 pixels and automatically adjust its height to maintain the image’s original aspect ratio. This ensures that the image does not become distorted when resized.

Of course, you can also use percentages to specify the image size. For example, if you want an image to take up 50% of the width of its parent element, you can set it like this:

.image {
width: 50%;
height: auto;
}

This way, the image will resize accordingly, regardless of the width of the parent element.

Image sizing in CSS is a crucial part of responsive design. By setting image width and height appropriately, you can ensure that your web pages display correctly on different devices and provide a good user experience.
