All of these things are possible, and we can help you do each one. Feel free to post a new topic on how to do a specific task. In the meantime, here’s a few links to manual/videos that should help 
- Getting Started Guide
- How to align components
- Let’s Rebuild this Tech Website
- Responsive Breakpoints
There’s are both good videos to watch for those coming from Classic or thinking about it:
Stick with Elements, once it clicks and you get the hang of it there’s no going back!
And again, please post a new topic if you get stuck and I’ll record a video showing you how to do exactly what you want
Cheers!
