I have an error message that is outputted as so:

\<%= flash[:notice] %\>

flash[:notice] is defined in my web\_controller. I want a fading effect  
on this text to draw more attention to it. Is there a simple way to do  
this that I can’t seem to find on Google?

I appreciate your patience.

You’ll have to use a javascript library. By default, rails includes the  
prototype.js library. Use the ajax helper methods to achieve the effect  
you desire.

You could also use jQuery.

Cheers,

Yeah, I’ve had a look at prototype already. I just wanted another option  
really. Thanks - I’ll look into jQuery.

Nope. This has nothing to do with Ajax – it’s just a JS visual effect.  
You can do it with [scrip.aculo.us/Prototype](http://scrip.aculo.us/Prototype), or with jQuery, or with any  
other JS library.
