1. I have my intro page that I want it to be in the center. On desktop it looks fine, but when it displays it on mobile device the logo just sit right at the top, and half of the screen is fill with background. so I want to center everything on that ONE PAGE.

2. In settings>reading.I set my front page as “splash page”, the problem is when I clicked the logo in home page it take me to front page. I want them to point to POST PAGE(home page). is there a solution to this or is it better setup.
front page -> splash page
post page -> home page
