Wix Web Specialist

I use Wix.com for my website and I need help with the following:

1) Make sure all page content (shapes, text, images) stays within the gridlines to prevent any elements from being hidden or pushed off the screen.
2) ***Ensure this site is optimized for mobile*** This is the most important part of this project. The site should be fully optimized to look and function seamlessly on mobile devices.
3) Ensure all buttons and links work and go where they should go. (Ex: "Contact Us" button should go to the "Contact Us" page)
4) Ensure the site looks professional and follows best practices.

This is a straightforward project, and if it goes well, it could lead to more in the future. Thank you!
