Moving elements

Hi everyone

I’m new to WordPress.

I’m having trouble moving anything around on my homepage.

candiceluper.com

I’d like to move the logo up (temporary logo), the menu down a little, the slider up and the body up. I’d also like to change the footer so that if I add another widget, it goes to the right not underneath.

I’m also having no luck with editing the child theme, whatever changes I have seem to have no effect whatsoever. I like the idea of wordpress but because each theme is so different and edited
differently, I don’t really see how anyone can ever really use it. Sorry to moan, I’m just frustrated by the whole process.

I’d appreciate any help. Thanks.
