How to put Add to cart beside Qauntity Selecter DAWN theme HELP PLEASE.

[PixiePawsPets]

Hello, I am using DAWN theme and would like to move my Add to Cart button betside the qauntity selecter however I am also using Seal Subscriptions and I if I use code: 

<style>
.product-form__buttons {
width: calc(100% - 150px) !important;
margin-top: -72px;
margin-left: 150px;
}
</style>

Into the theme.liquid file above </head> it changes all products and works perfectly except for my Seal Subscription products. it ends up looking like this: 

Is their a way I can either exclude certain products without it effecting the seal subscriptions app products or is their a way I could please also have Add to Cart beside the qauntity selecter (which would be preferred)

New to coding, step by step please & thank you
