change font-size and color of the price and productname

I want to Change the font-size and Color of each Price and productname.
Which class Name must I take and where and how can I Change it.
kindly regards

Hey there,
I hope you’re doing well today

You’ll need to write the code like this.
Simply change the product ID number to the product you’d like the CSS applied to.

/*product title color and font*/
div#product-37 .product_title{
  color: red;
  font-size: 40px;
/*product price color and font*/
div#product-37 span.woocommerce-Price-amount.amount{

Best Regards,
