Landing Page, finally can see it in a cell-phone

Hi campers! It seems at last I worked around my way and now I can see it OK in the cell-phone screen. I did a little Photoshop design. Does it count? It was the only way I could enter text without messing the nav-bar, which by the way was working fine when I took it out of the header. But I defeated the header.
Please tell me what you think.

I’m sorry I tried to remove this topic because my pen isn’t ready yet. I’ll try to make important changes in the layout so I’ll make a new topic when it’s ready. Sorry @sobadrdb I deleted the post you liked. You did me incredible good with that flex page and I’m gonna use it to the max. Thanks again!
