What Are The Advantages of Building a Web-Page with Django as Opposed to Solely Using HTML5/CSS3?
Django is a python web application framework that allows you to send requests from your page to a server that will in turn provide a response back to your web page.  

Advantages: The power of Django is the ability to quickly get both the client ( your page ) and the backend ( the server-side logic ) setup.  The backend can include writing to a database, processing information, retrieving information which is subsequently a response delivered to your web page. 
HTML5/CSS3 is markup languages for your web page.  You can use a editors like sublime or even notepad ++ if you are building a static web page. Django, like most web app frameworks, are used because of what I've described in #1 ( and many other unlisted reasons ).
HTML5 provides the ability to make dynamic web pages ( using a client side library like JQuery as an embedded script ), Django helps you build web apps.  You can write a web page using only HTML5 and JQuery to display list of tv shows that are currently on ABC by listing what is currently playing today, but what about for tomorrow?  You need server-side help by creating response that will fetch all shows for tomorrow by calling the ABC API.  Take a look at server-side logic and web applications. 

In short, there are web pages and web applications.  Sounds like to me you are building the former, so Django might be overkill.
Essentially, my questions are as stated above in the title. What I'm really seeking to know is why it would be privy of me to build a web-page utilizing the Django framework as opposed to solely building it out with HTML5 and CSS3. 
I do know that Django utilizes bootstrapping of HTML5 and CSS and this is where my questions are raised over the efficiency of using the Django framework as opposed to solely using HTML5/CSS3.
1.) What are the advantages of Django?
2.) What does utilizing the Django framework offer me that HTML5/CSS3 do not? 
3.) HTML5 can also build dynamic web-pages as can Django. Why would Django be better for a dynamic web-page?
I am looking for a very valid answer here as I am about to start building my web-page. The responses I get to these questions will be the nail in the coffin for which method I will be using to build the web-page. Thanks ladies and gentleman and I hope you find this question to be worth your while in answering.
