Reset.CSS repeats HTML Selectors

Permalink
Hi there,

As I wanted to change a number of things in the CSS of the standard Greek Yogurt Theme. I firstly copied the theme from the standard location and pasted and renamed it to the public html/theme folder.

Then looking through the CSS in this 'new theme' I noticed that in the reset.css file that many of the selectors are duplicated: i.e. on the first line all the selectors are there separated by a comma then below some, which have css declarations are mentioned again. like this:
line1: a,abbr,acronym,address,applet,article,aside,audio,b,big,blockquote,body,canvas,
line#: body {height:100%}

Are they there for a reason?
Can I clean this up and remove all doubled up selectors?
Can I put them in alphabetical order which would make more sense to me?

Thanks for any input in trying to understand this.
