Custom style for a progress bar updating a textbox

Hi,

I wish to set up a custom progressbar and message, with a different style than the default one.

For instance when using an async command to update a textbox value, the progress bar shown when performing the action call makes the textbox to be filled with progressbar which is to big to fit.

I have tried to override the css style caf-progress-box but then of course all of the progress bars is changed, which is not my intension.

Regards,

Eric Piper
