Need help aligning modals side by side : Hey StackOverflow Members!

This is my first post. I usually find all my solutions to problems on here, but this question I cant seem to find the answer to. I am horrible at coding, but a am learning by making lots of mistakes. Im most comfortable with CSS and HTML, however java and other codes scare me to death! Speaking of JAVA, I am using modals for a website page I am working on. Everything has been working good, but I cant seem to get them to align how I would like them. If you do answer with a solution, if you could explain it so I can make this a learning process that would be great :)

So here it goes. I am trying to make a web page which has 3 buttons which trigger a modal. A Monthly Subscription, Yearly Subscription, and Purchase Add-Ons. Both membership buttons open a modal with a PayPal subscription page. Now as soon as I add the PayPal code, i loose the ability to keep the 2 buttons side by side. Instead they are stacked. I have tried <Center>, Text-Align, Putting the modal in a DIV, and still no success. 

**Here Is The Code** (Yes I know...tisk tisk I have CSS with my HTML)

I dont know how to add code in this message correctly. Hope this is ok.


Any help would be great :)
