Description
Exercise 1
Below is an example of an invalid XHTML page. Your goal is to rewrite the code so that:
• No deprecated/obsolete tags are being used
• All elements are nested correctly (i.e. Hello)
• It validates as XHTML 1.0 Strict (See https://validator.w3.org/)
• Presentation is separated from content (All style should be specified in the head)
