[Feature] Improved Accessibility

[anonymous390759]

convert.to.it does not comply with various internet accessibility standards.
Here are the following details to improve:

Insufficient Color Contrast more info

Non-Focusable Elements more info

Invisible Text Labels more info

These parts of the code should be changed in order to improve user accessibility.

Rather than treating this as a separate issue, I'll tag #73 here to add it for consideration for the redesign. I don't think we'll be changing the frontend much until that comes along.
