Hi, On another video Nick used two stylesheets, one to normalize and the other to apply a new style. Is that necessary?
I mean, to normalize the different browser's default stylings. Is that always necessary or in which cases would that be the important?

Every browser comes with it's own base stylesheet... these bases are not necessarily consistent and may counteract some of the styles in your stylesheet. You want to start with a clean slate, and by attaching the normalize stylesheet, you are provided with this clean slate. In one of the later courses under "CSS Layout Techniques," Guil actually edits a normalize stylesheet. I highly recommend taking the course.

Normalize is an easy way to set up some basic styles that will work across all browsers. It sets up the basic behaviors you'd expect to see in any website. He placed that one first in the html doc so that the Main.css file he was using could override any styles. Hence the term "Cascading Style Sheet". The one placed furthest down in the html doc gets preference, but if there are no new rules the previous one's rules apply
It is not necessary, but it is very common to do so.
Many of us have a normalization stylesheet that we have developed over time with our preferences etc to remove specific browser inconsistencies. Some people just have a like a few normalizations and will just list them at the top of their main stylesheet instead of in a separate stylesheet.
