Selfclosed

Selfclosed refers to a programming concept primarily found in markup languages like HTML and XML. It describes elements that do not require a closing tag. Instead, their opening tag contains all the necessary information to define the element and its content, if any. This is often achieved by appending a forward slash to the closing bracket of the opening tag. For example, in HTML, the line break element is typically written as <br/> or <br>. Similarly, an image element is written as <img src="image.jpg" alt="Description"/>, where the tag itself defines the image source and alternative text. The term "self-closing" emphasizes that the element is complete and terminates its own definition within a single tag. This syntax helps to simplify markup and reduce the potential for errors caused by mismatched opening and closing tags. Not all elements support this syntax; it is specific to the design of the markup language and the nature of the element being defined.
