Can You Nest Buttons in HTML?

Nesting Buttons: A Semantic Conundrum

Can button elements be nested within other buttons? The answer, according to the W3C recommendation, is a resounding no. The specification specifically states that "Phrasing content, but there must be no interactive content descendant."

Interactive content includes elements that allow user interaction, such as buttons, input fields, and links. Therefore, nesting a button within another button violates this rule.

In the provided HTML example, the child button is not responsive to CSS styles and appears outside its intended container. This is because the DOM parser interprets the nested button as a separate, independent element, not as a descendant of the parent button.

Since nesting buttons is invalid, developers seeking a solution must consider alternative approaches. One option is to replace the parent button with a different element, such as a div or span. However, it is important to select a tag that semantically aligns with the desired functionality.

For example, if the parent element's purpose is to toggle the visibility of a section, it could be replaced with a details or summary element. Alternatively, if the element's role is to trigger an action, a button or link element would be more appropriate.
