After the assessment I felt extremely comfortable with everything we have talked about, A LOT better then I expected actually. I found the errors and corrected them efficiently and quickly.The one that took me the longest (and it wasn’t all that long honestly) was the table. Since we haven’t really used them it kind of caught me off guard but, I finally realized it was missing the closing tag.
Other than that I am pretty comfortable with everything. When ever I forget something OR need help on somethings we haven’t discussed I am on google like white on rice. I mainly use http://www.w3schools.com/w3css/default.asp because it’s super easy to understand and they have a demos page that makes it even easier then most. In all actuality whatever google feeds me that I can look at and see how to do things coding wise is what I use. I’ve used a bunch of random sites and forums where people have shared some code and explained how it all works.
Overall though w3 school is where it’s at. 
I agree with the table on the troubleshooting assessment! It was so easy to miss it, but an easy fix. I’ve heard a lot of great stuff from w3 schools so I will have to check it out.
I love w3schools! It has helped me out so much!
