CourseBuffet Instant answer

**What does your instant answer do?**
Displays relevant free online college courses

**What problem does your instant answer solve (Why is it better than organic links)?**
There are over 1200 free college courses available but they are created by over 200 universities and spread over a dozen platforms. A user can go to each provider’s site or go to a site that aggregates courses. Both of these methods are time consuming. The aggregation sites cut down on the time a little bit but the user is still faced with lots of courses to look at with little direction and has to figure out which courses are directly comparable and which order to take courses. 
CourseBuffet is better. We look at each course individually and then classify it under a subject, generic title and level/year that is roughly equivalent to what the course would be at a US university. This enables users to know which courses are directly comparable even if their title is different. No more time consuming searching and guessing! This also allows them to get a good idea of what order to take courses even if they are taking courses from multiple providers/platforms.

**What is the data source for your instant answer? (Provide a link if possible)**
CourseBuffet(http://www.coursebuffet.com) - We(CourseBuffet) receive the data from providers(MOOCs) then we use our own classification system to create our own database. This means a human looks at every course and analyses it. This gives users the most relevant results.

**Why did you choose this data source?**
Our database produces better results and saves users’ time and lessens their confusion.

**Are there any other alternative (better) data sources?**
No - There are other sites that aggregate courses from different MOOCs, but does not properly classify it.

**What are some example queries that trigger this instant answer?**
"computer science course", "Human Physiology", "udacity computer science"

**Which communities will this instant answer be especially useful for? (gamers, book lovers, etc)**
People trying college education for the first time and people who are lifelong learners

**Is this instant answer connected to a DuckDuckHack [instant answer idea](https://duck.co/ideas)?**
Not that we could find. We were approached by DDG to create this instant answer

**Which existing instant answers will this one supersede/overlap with?**
None that we could find

**Are you having any problems? Do you need our help with anything?**
In development environment, it seems like the `text` template is not behaving properly on Firefox and IE, the link to the individual tile does not go anywhere, It works on Chrome/Safari/Opera. I tried running the `github_search` answer on my dev server and it had the same issue, any help on this will be great!

- Ellipsis at the second line (because of `-webkit-line-clamp: 2`)
- The professor gets overlayed on top of the title.
