Velo and multi-state boxes

Hi guys.

I have created an X close icon in a multi-state box using velo code.

It works great except, on tapping the close icon on mobile devices, it is briefly highlighted in grey to signify that the on-click command has been triggered.

Does anyone know how to disable this grey flashing please?

If (and only if) your website is connected to your own domain, you can try the following (I haven’t tried it, so I can’t promise it will work):
Go to Site Dashboard > Settings > Custom Code.
Create a snippet with the following code, set to head and apply to the relevant page:

 * {
 -webkit-tap-highlight-color: transparent;

Many thanks! Your help is very much appreciated.

It has worked perfectly - really chuffed!
