Wording and grammar.  (#200)

* Update :smile:

Wording, grammar
Removed contractions ie we're to we are for consistency (we're was used sometimes and we are others) and formality 

On ln 9: specified what "these" effects were 

:smile:

On ln44: the comma between 'css file ...' and 'if' is not needed and creates an unnecessary pause

* Returned contractions

* Update README.md
