In the shayhowe site it is mentioned that ..

Here is the answer that always made the most sense to me. Normalize does change a lot of things but it keeps some of the default padding around block level elements and other things that are right about the browser default agents. Reset.css is kinda like a nuke it sets everything to 0 and lets you build from square one. I find that when I use Reset.css a lot of times I have to put back in margin, padding, etc that normalize would have kept. So if you want to start a project from CSS scratch and control padding, margin, and everything from the get go use Reset If you just want to make things look the same everywhere and tinker a little bit with styles use normalize.css

All normalise does is resets the default browser styles for all the major browsers so that when you're starting a project, you're on as big a level playing field as possible and all browsers should look the same.

But if you want to customise it, that's when you should familiarise yourself with what's going on inside the CSS file.

If you want to use normalize.css like this...

<link rel="stylesheet" type="text/css" href="normalize.css" />

As it would appear in the head element on a HTML document, then make sure it is the first file referenced in your list of CSS files. Remember that the order of styles applied in a HTML document matters. :-)

Good luck!

This one I'm talking about

There are a bunch of different resets available to use, all of which have their own fortes. One of the most popular resets is Eric Meyer’s reset, which has been adapted to include styles for the new HTML5 elements.

If you are feeling a bit more adventurous, there is also Normalize.css, created by Nicolas Gallagher. Normalize.css focuses not on using a hard reset for all common elements, but instead on setting common styles for these elements. It requires a stronger understanding of CSS, as well as awareness of what you’d like your styles to be.

Normalize resets a lot more than reset.css does, so it just depends on what you need. I tend to use normalize over reset as it's a bit more comprehensive and I find how opinionated it is generally still works for me.
