Image Attributes

Image attributes are used to provide additional information or control the appearance and behavior of the `<img>` element. Some commonly used image attributes include `src`, `alt`, `width`, `height`, `title`, and `style`. Here's an explanation of each attribute along with examples:

  1. `src` (required): Specifies the URL or path of the image file to be displayed. The image file can be in formats like JPEG, PNG, GIF, SVG, or WebP.

Example:

<img src="example-image.jpg" alt="An example image">
  1. `alt` (required): Provides a text description of the image, which is displayed if the image cannot be loaded. The `alt` attribute is also important for accessibility, as screen readers use it to describe the image to visually impaired users.

Example:

<img src="example-image.jpg" alt="A beautiful landscape">
  1. `width` and `height`: Define the dimensions of the image in pixels. Setting these attributes can help improve the page layout, as the browser knows the image size before it loads, which prevents content reflow.

Example:

<img src="example-image.jpg" alt="A beautiful landscape" width="300" height="200">
  1. `title`: Provides additional information about the image, which is displayed as a tooltip when a user hovers over the image with the mouse pointer. While the `title` attribute can be helpful, it's not a substitute for the `alt` attribute, as screen readers may not read the `title` attribute.

Example:

<img src="example-image.jpg" alt="A beautiful landscape" title="Landscape with mountains and a lake">
  1. `style`: Inline CSS styles can be applied to the `<img>` element to control its appearance, such as border, margin, or padding. However, it's generally recommended to use an external stylesheet for better organization and maintainability.

Example:

<img src="example-image.jpg" alt="A beautiful landscape" style="border: 2px solid black;">

Here's a combined example demonstrating the use of various image attributes:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Image Attributes Example</title>
</head>
<body>
    <h1>Image Attributes</h1>
    
    <h2>Image with Src and Alt Attributes</h2>
    <img src="example-image.jpg" alt="A beautiful landscape">
    
    <h2>Image with Width and Height Attributes</h2>
    <img src="example-image.jpg" alt="A beautiful landscape" width="300" height="200">
    
    <h2>Image with Title Attribute</h2>
    <img src="example-image.jpg" alt="A beautiful landscape" title="Landscape with mountains and a lake">
    
    <h2>Image with Style Attribute</h2>
    <img src="example-image.jpg" alt="A beautiful landscape" style="border: 2px solid black;">
</body>
</html>

Remember to always include the `src` and `alt` attributes for all `<img>` elements, and use external stylesheets instead of inline styles when possible for better organization and maintainability.
