What is the default border of an image?

The default border of an image typically refers to the styling parameters that define how the image is displayed within a web page or application. In HTML and CSS, images usually have no border by default, meaning they are displayed without a visible outline. However, users can apply CSS styles to add borders, adjust thickness, and change colors as needed. The absence of a default border allows for flexible design choices based on the context of the image's use.
