I just want to share something that you might already know anyway, but I couldn't find it in the forum.
I had for a while problems to display borders on elements with Hotmail. I tried to break down the border shorthand declaration to see if it would work but nothing changed.
Eventually i found that if you use color keywords in the css declaration then Hotmail display the borders without any problem.
I go back to the rest of my Hotmail probnlem list.
merry christmas a bit late to you all :)
Just to say that i encountered this issue with inline style, style from the<head><style></style></head> are fine.
