Missing gradients in the learn.jquery.com CSS

[mgol]

learn.jquery.com CSS includes many vendor prefixes for linear-gradient but it misses the most important form: the prefixless one. An example:

    background-image: -webkit-gradient(linear, left top, left bottom, from(#ffea94), to(#FFEA5E)); 
    background-image: -webkit-linear-gradient(top, #ffea94, #FFEA5E); 
    background-image:    -moz-linear-gradient(top, #ffea94, #FFEA5E); 
    background-image:     -ms-linear-gradient(top, #ffea94, #FFEA5E); 
    background-image:      -o-linear-gradient(top, #ffea94, #FFEA5E); 

from:

jquery-wp-content/themes/learn.jquery.com/style.css

Lines 56 to 60 in 28fe8bd

	background-image: -webkit-gradient(linear, left top, left bottom, from(#ffea94), to(#FFEA5E));
	background-image: -webkit-linear-gradient(top, #ffea94, #FFEA5E);
	background-image: -moz-linear-gradient(top, #ffea94, #FFEA5E);
	background-image: -ms-linear-gradient(top, #ffea94, #FFEA5E);
	background-image: -o-linear-gradient(top, #ffea94, #FFEA5E);

By the way, Opera doesn't need a prefix since 12.10 (the last Presto version, current version is 26), Firefox from 16 (current version is 34); IE has never needed a prefix (only IE10 previews required one). The older WebKit gradient form also doesn't seem to be needed; the newer one is needed for the Android Browser. We only really need two forms IMO:

    background-image: -webkit-linear-gradient(top, #ffea94, #FFEA5E); 
    background-image:         linear-gradient(to bottom, #ffea94, #FFEA5E);

Other sites do this kind of things too. Not only with gradients btw. I'il assign this to me, I'm able to fix it shortly. Update: Oh. correct. I can't assign people here

This was also the reason why I wanted to re-open #66.
