Button styling

Hi,

Could I ask how to contorl the css on the ‘show/hide’ button?

I’m using the Quick ccs and able to control most of the features, but it is ignoring my request for a black border. Should i be using a another class to control that aspect?

I’m using the following css:

a.button, button, input[type=submit], input[type=reset], input[type=button] {margin-left:30px!important; margin-bottom:10px!important; color:black!important; background:white!important;border-color: black!important; border-radius: 0px!important; border:1!important}

Kind regards,
A
