Recent posts

Hello,

Currently my recent posts on my homepage are posting one underneath the other. I want it to be two posts per line. The plugin I am using to post on my homepage is Posts to Page. Also, my banner is not stationary. The position changes whenever I minimize or maximize my screen. It also looks different on different size screens likes phones, macs, hp’s etc. Thank you in advance for your help. The link to my website is simplyjess.com.
