Better solution than using JavaScript alerts to show output of quizzes

[jkokocha]

Currently, when submitting an answer in quizzes (as seen in some info/content pages), the output is given in the form of a JavaScript alert.

This should be upgraded, so that the output displays on the page itself.

The outputs may be changed to make this solution prettier. Some ideas are:

• Remove the submit button, instantly get a response when clicking on the answer.
• Quiz responds in color instead of text, the selected option lighting up in red or green depending on if the answer is correct. This could also be coupled with some text below.

However, these are just ideas. If you have a better solution, please go ahead and give it a shot! This issue is not straightforward, and whoever decides to help with it should be ready to get creative and create a good, modular and pretty solution for quiz output that doesn't introduce limitations. There's quite a bit of freedom here!
