Empty HTML elements refer to elements that do not have any content or closing tag. 

These elements are also called void elements or self-closing elements. 

Examples of empty HTML elements include the <br> and <hr> tags, which are used to create line breaks and horizontal lines, respectively. 

Empty elements can be written as either <element> or <element />, with the latter being more commonly used in XHTML and XML documents.

Examples of empty HTML elements include:

<br>: creates a line break

<hr>: creates a horizontal line

<img>: displays an image

<input>: creates an input field for user input

<link>: creates a link to an external resource

<meta>: provides metadata about the document

<source>: specifies the source of a video or audio element

<wbr>: indicates a possible line break opportunity

Note that these elements are written as self-closing tags, like <br />, <hr />, <img src="image.jpg" />, <input type="text" />, <link href="styles.css" rel="stylesheet" />, <meta name="description" content="A website about cats" />, <source src="video.mp4" type="video/mp4" />, <wbr />.
