Creates an input with a visual, non-editable prefix.

• Use display: flex to create a container element.
• Remove the border and outline from the <input> field. Apply them to the parent element instead to make it look like an input box.
• Use the :focus-within pseudo-class selector to style the parent element accordingly, when the user interacts with the <input> field.
