Hide and Show Textareafield border

[UbuntuPenguin]

Hello Everyone,
I have a Textareafield and I would like to show its border AND shadow while it is editable and hide it while it isn't. What is the best practices way of doing this. I have thought of using CSS, but I have absolutely no idea of how to use dynamic(?) css and there doesn't appear to be a border transparency option on the Textareafield class.

Any help is greatly appreciated.

You could set the focusCls (and overCls) for when active and cls when not?

After many hours and even more curse words, turns out I needed to use the 'readOnlyCls' property of the textareafield. My css looks like something like this.

.instructions-read-only .x-form-item-body textarea
{
border-top-style : hidden !important;
border-bottom-style : hidden !important;
border-left-style: hidden !important;
border-right-style: hidden !important;


background-image: none !important;
}

Thanks for the help and leading me down the path of looking for the various state csss.
