What Are The Advantages of Building a Web-Page with Django as Opposed to Solely Using HTML5/CSS3?
1.) What are the advantages of Django?
Server-side scripting without the necessity to use PHP. If you already worked with Python, you don't need to learn another language for you server-side.
2.) What does utilizing the Django framework offer me that HTML5/CSS3 do not?
Hm, deployment to a server, handling user requests and dynamically generated webpages. You mentioned making an intricate website in a comment. I don't know what you mean by that, but a framework will let you do this way faster then without. Especially, if you only rely on client-side JS with static HTML5 and CSS3, I'm fairly certain you will have a hard time achieving your goal.
3.) HTML5 can also build dynamic web-pages as can Django. Why would Django be better for a dynamic web-page?
I'm not really sure you understand what dynamic means. Dynamic means generated from code, as opposed to static, which means served directly from an .html file. Django let's you do both, it's a framework and offers lots of flexibility.
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.
