Invisible Options on Checkout Page/Products

My whole checkout page is blank/invisible. If you highlight the entire page you can see everything properly such as where you fill in your Address, Full Name, and basically all of your checkout information. This is also occurring on some of my products on the shop page and also when you want to click onto the 2nd page of an item, you cannot see the numbers (2,3,4,5..etc). Some will not show the price under them, but when highlighted you can clearly see it. This is making me lose a lot of customers because they simply cannot navigate my website or even checkout properly. Please place an item in your cart to see the issue or just browse the website. Any help is greatly appreciated!
