Explanation:

HTML:

The DOCTYPE declaration specifies the document type and version of HTML being used.

<html>: Defines the root element of the HTML document.

<head>: Contains meta-information about the HTML document, such as the character encoding and viewport settings.

<meta charset="utf-8">: Specifies the character encoding of the document to UTF-8.

<meta name="viewport" content="width=device-width">: Sets the viewport width to the width of the device.

<title>: Sets the title of the HTML document.

<body>: Contains the content of the HTML document.

<img>: Inserts an image element.

class="image image-contain": Specifies classes for the image element, allowing CSS styling.

src="https://www.w3resource.com/html-css-exercise/html-css-practical-exercises/flower-9.jpeg": Sets the image source.

The second <img> element has similar attributes but with a different class name (image-cover).

CSS Code:

.image { background: #34495e; /* Comment: Sets the background color of the image */ border: 1px solid #34495e; /* Comment: Sets a solid border around the image */ width: 200px; /* Comment: Sets the width of the image */ height: 200px; /* Comment: Sets the height of the image */ } .image-contain { object-fit: contain; /* Comment: Specifies how the image should fit inside its container */ object-position: center; /* Comment: Specifies the position of the image inside its container */ } .image-cover { object-fit: cover; /* Comment: Specifies how the image should cover its container */ object-position: right top; /* Comment: Specifies the position of the image inside its container */ }

Explanation:

CSS:

.image: Styles applied to all elements with the class "image".

background: Sets the background color of the image.

border: Sets a solid border around the image.

width: Sets the width of the image.

height: Sets the height of the image.

.image-contain: Additional styles applied to elements with the class "image-contain".

object-fit: Specifies how the image should fit inside its container. In this case, "contain" ensures that the entire image is visible while preserving its aspect ratio.

object-position: Specifies the position of the image inside its container. In this case, "center" horizontally centers the image.

.image-cover: Additional styles applied to elements with the class "image-cover".

object-fit: Specifies how the image should cover its container. In this case, "cover" ensures that the entire container is covered by the image while preserving its aspect ratio.

object-position: Specifies the position of the image inside its container. In this case, "right top" positions the image to the top right corner of its container.
