10. Ready?


#1


On the stylesheet, why are there two .pull-me class selectors defined?


.pull-me{
    -webkit-box-shadow: 0 0 8px #FFD700;
    -moz-box-shadow: 0 0 8px #FFD700; ...

&

.pull-me {
    display:block;
    position:relative; ...


#2

A number of developers separate the selectors so vendor prefixes are written exclusively in one, and normal W3C selectors written in the other.


#3

Interesting.

Thanks!

Should have added that with the advent of CSS3 it was common to see CSS 1 and 2 written in one selector rule, and CSS3 rules written in another.


#5

Helpful insights, again. Thanks.
