opacity

Using LESS, I know that I can change the saturation or tint of a color variable. That looks like this: background: lighten(@blue, 20%); I want to change the alpha opacity of my color, though.

I'm having some issues on creating a fade in effect of a grid. I want a grid coming out after a click, is this possible? Thanks! You can use a Storyboard and animate the Opacity property to produce a Fade In effect, the following thread covers the code required :- http://social.msdn.microsoft.com/Forums/is/windowsphone7series/thread/a8e05145-364d-412c-8fb5-faf65e80344e A tad too late to the party, as I just wrote pretty much the same as Hermit Dave, but maybe it helps to contribute to an even better understanding: Another way is, setting your Storyboard items in XAML view, which, in my opinion
