Range: surroundContents() method
The surroundContents() method of the Range interface surrounds the selected content by a provided node. It extracts the contents of the range, replaces the children of newParent with the extracted contents, inserts newParent at the location of the extracted contents, and makes the range select newParent.
An exception is thrown if the range partially contains any non-Text node. The range must only contain text nodes and completely selected nodes.
