I dont know the default style, but you can apply the same CSS to both, overriding the existing CSS.Something like .charsheet button.yourstylename { /* your style here */ } or .charsheet button[type="action"].yourstylename, .charsheet button[type="roll"].yourstylename { /* your style here */ } You can find the current CSS, by using the browser's inspect feature (usually rightclick the button and select Inspect or a similar label).
