An icon is a graphic that represents a website or application. They are often used on webpages and applications to help users find and identify the source.
In most cases, icons are made up of a series of small squares or rectangles.
There is no one specific icon design, but most icons typically use a simple, geometric shape. Icons can be brightly coloured or completely black and white, but they are typically designed to stand out and be easily recognisable.
Some popular icon designs include the Windows 10 Start Menu and the Apple Watch Home Screen. While there is no definitive answer to what the blog icon should look like, many popular blog platforms, such as WordPress and Medium, use icons that generally resemble this simple design: a rectangular box with a small circle in the middle.
