Some element IDs use underscores and others use dashes

[nfoert]

I'm not really sure how this happened. The IDs with dashes (-) should be replaced to use underscores (_) instead.

@nfoert is this like a major refactor? If so, would you think it would be ideal after the automated tests have been implemented then we should tackle this?

@mSaurabh, it's not too much of a change, there's just a few element IDs from the first few weeks of this project using dashes instead of underscores, it could probably be fixed now, it's just not something that I've gotten around to yet

[mSaurabh]

I can take this quick clean up @nfoert

Sounds good, thank you @mSaurabh!

@nfoert I have refactored the code. Here's the PR.
