Big Questions


Welcome to our home page. We are going to attempt to answer the hardest questions in the universe!




The big question #1


The meaning of life? Arrg. Do tell us what you think!


Responses:


{% for review in reviews %}
	
{{review.title}}

	
Name:{{review.name}} on date:{{review.date_posted}}

	
Review comment: {{review.comment}},

{% endfor %}


{% endblock content %}

  The second line {{% block content %}} contains an invisible styling block

  The img tag contains a link to the CSS styling document.

  It is most likely contained in the layout.html page which it is inheriting from.

  It is most likely contained in an external HTML file which is not part of this project.

 9. The following code seeks to link the About link to the about page. What is missing?

  The code should be: {{url_for('about')}}

  Nothing is missing. The code is correct.

  The code should be: {{url_include('about')}}

  The code should be: {{url:('about')}}

 10. The following is the code contained in the about.html page. The page will not render correctly. Can you spot what is missing? 
{% extends "layout.html" %}
{% block content %}
