    The correct way to write a self closing tag

    In HTML, closing a self closing tag with its closing tag is invalid. For example, closing a tag like is not valid.

    But the question is do we need to close these tags by using /> at the end of the tag. i.e
    ,

    The fact is there is no need to close self closing tags by a slash /> at the end of the tag. Although many people use it but there is no meaning of slash at the end of the start tag even though you use it is ignored by the browsers.

    But when using XHTML it is the rule to close the self closing tag by a slash at the end, so for the convenience of XHTML users HTML also allows closing tag like XHTML in HTML but simply ignores the slash.

    Even if you close the tag browser remove the slashes and then render the element. You can see the picture below to understand.

    Note - Even if the browser ignores the closing slash in void tags, it's good practice to close it because:
    1. in frameworks like react js if these are not close, it creates an error
    2. if you want your document to be readable by an XML parser then must close all elements
