Image Elements in HTML

In this tutorial, we will explore Image Elements in HTML, which are used to embed images on a webpage. The <img> tag is used to display images in HTML, making it an essential element for enhancing the visual appeal and user experience of a website.

Key Points to Understand About Image Elements

Image Tag:

• The <img> tag is used to embed images on an HTML page.
• It is a self-closing tag, meaning it does not require an end tag.

Attributes of the <img> Tag:

• src (Source): Specifies the path to the image file. This is the most important attribute.
• alt (Alternative Text): Provides a text description of the image for accessibility purposes and when the image cannot be displayed.
• width: Defines the width of the image.
• height: Defines the height of the image.
• title: Adds a tooltip to the image, which is displayed when the user hovers over it.

Responsive Images:

• To make images responsive and adjust their size according to the screen width, use CSS properties like max-width: 100% and height: auto.

Image Formats:

• Common image formats used in HTML include JPEG, PNG, GIF, and SVG.
• Each format has its advantages: JPEG is best for photographs, PNG is ideal for images with transparency, and GIF is used for animated images.
