Choose Options / Add To Cart button too big on mobile

[centralperkp]

On mobile, the buttons to Choose Options or Add to Cart are too big, on mobile. Both in my main page and in the collection page. How do I edit this? I tried some of the codes from other topics, but was not successful. Thank you so much! 

my website is centralperkpets.com. 

Any help is greatly appreciated.

Add this style to base.css file

@media(max-width: 767px){
.quick-add__submit {
    min-height: 30px !important;
    font-size: 12px !important;
}
}
