How Can I Display Only a Portion of an Image Using HTML and CSS?

Displaying a Portion of an Image in HTML/CSS

When displaying an image, you may sometimes want to showcase only a specific part of it. HTML and CSS offer several techniques to achieve this.

Using the CSS 'Clip' Property

One approach is to use the 'clip' property in CSS. However, this property requires the element to be positioned absolutely, which can pose limitations in certain scenarios.

.container {
  position: relative;
}
#clip {
  position: absolute;
  clip: rect(0, 100px, 200px, 0);
}

Using 'css:url()' References

If you're working with 'css:url()' references, clipping the image is not directly feasible in CSS. In such cases, you can consider using the 'image-slicing' technique, which involves slicing the image into smaller parts and displaying only the desired portion.

<div class="container">
  <img src="image.jpg">

This technique allows you to display only the central 50x50px portion of the aforementioned 250x250px image.

Alternative Approaches

If you cannot use absolute positioning or the 'image-slicing' technique, you could explore other methods such as:

• Cropping the image: Crop the image externally using image editing software and use only the cropped portion.
• Using JavaScript: Use JavaScript to dynamically adjust the display size of the image, cropping it on the fly.
• Using an image viewer: Employ an image viewer that provides cropping functionality, such as the 'Image Viewer' tool in modern browsers.
