Is it possible to enlarge the "Send" button?

My SEO advisor has encouraged me to enlarge the “Send” button on my Contact Form 7 contact form so it’s physically larger, making it easier for visitors to see and click it.

Is that possible? How would I do it?

If not, is it possible to do something else to highlight it, like changing its color?

Thanks!
