Why should I use UL/LI in my HTML?

Question

I have the following structure that seems really nice for me and I always use HTML5:

Answer 1

Since the release of HTML 5,

can be used for website navigation block instead of div.

Referring to the HTML Standard

The nav element represents a section of a page that links to other pages or to parts within the page: a section with navigation links.

The HTML Standard includes an example that use

followed by

and
• .

  
    
  
     
  Home
     
  Current Events
     ...more...
    
  
  

  But it also says

  A nav element doesn't have to contain a list, it can contain other kinds of content as well.

  
   
  Navigation
   
  You are on my home page. To the north lies my
   blog, from whence the sounds of battle can be heard. To the east
   you can see a large mountain, upon which many school papers are littered. Far up thus mountain
   you can spy a little figure who appears to be me, desperately
   scribbling a thesis.
  
  

  Based on the Standard, the use of ul and li is personal preference as long as you have nav to indicate navigation.
