Twenty Twelve needs updates too.
And the new patch attached for other css files.

Thanks for your patch @man4toman,

In order to better track issues in each theme, could you please remove the Twenty Twelve fix from your patch and create a new ticket just for that theme. Thanks

Hi @ianbelanger
The new patch attached, I'll create a new ticket for "Twenty Twelve".

[ianbelanger]

Changes gradient direction in linear-gradient

[ianbelanger]

As pointed out by @joyously in #46786

The patch doesn't actually fix the problem, because this ticket was just written for syntax. The real problem is that the old syntax goes the other direction from the new syntax.
For example,
-webkit-linear-gradient(top, #f4f4f4, #e6e6e6);
will start at top with #f4f4f4 and go down to #e6e6e6. But
linear-gradient(to top, #f4f4f4, #e6e6e6);
will start at bottom with #f4f4f4 and go to top to #e6e6e6.

So in 46770.4.diff I have switched linear-gradient to use to bottom to correct the issue.

In 45109:

Twenty Eleven: Correct linear-gradient direction argument syntax.

In CSS, the linear-gradient function requires that the direction value explicitly use to instead of an implicit from.

Fixes #46770.
