btnIcon

btnIcon refers to a common naming convention used in software development, particularly in front-end web development, to identify and style elements that represent an icon within a button. The prefix "btn" typically signifies that the element is part of a button component, and "Icon" indicates that its primary purpose is to display an icon.

This convention helps developers quickly understand the role and styling of a particular HTML element, such as a `<span>` or `<i>` tag, when it's used in conjunction with a button. For example, a CSS class named `btnIcon` would likely contain styles for the icon's size, color, and positioning within the button. It might also be used in conjunction with other classes to specify different types of icons, such as `btnIcon-search` or `btnIcon-save`.

The use of `btnIcon` as a class name promotes a structured and maintainable codebase. It aligns with object-oriented CSS principles, where components are broken down into smaller, reusable parts. This makes it easier to manage styles, update icons across an application, and ensure visual consistency. While not a formal standard, it's a widely adopted practice that contributes to efficient front-end development workflows.
