I am developing a mobile theme for my dynamic website. I heard about the role of Viewport in converting a website to mobile-friendly. How can I set the Viewport on a custom dynamic website?

I have a small website developed in PHP and HTML 5. Now, I plan to publish it. Though it is a small website, it has a high potential to grow.

My problem is finding the right web hosting for this website. How can I find the best web hosting account for this new dynamic website?
