Images play a crucial role in enhancing the visual appeal and conveying information on web pages. In HTML, images are inserted using the <img>
tag.
Inserting Images
The <img>
tag is used to insert images into an HTML document. Unlike most HTML tags, the <img>
tag does not have a closing tag and is self-closing.
Example:
In the example above:
- The
<img>
tag is used to insert an image; - The
src
attribute specifies the source (URL) of the image file; - The
alt
attribute provides alternative text for the image. This text is displayed if the image cannot be loaded or for accessibility purposes.
Before exploring a real-world example, let's understand the essential attributes of the img
tag and how they impact its content.
