Multiple modification on 2011-child theme.

Hi!

First I want to say that I’m not very skilled in css and generally codes. I’m more into design to be honest. But right now I’m making a WordPress site for a company, and I need some help.

Here’s the site: https://oraeiendomverdal.no/

Parent theme is 2011. Yes, I have managed to make a child theme : D

Ok, so here we go:

1. Remove the shadow from the menu. So far I have managed to remove the gradient to a solid color.

This is the CSS for the menu right now:
#access {background: #f15a22;}

2. Remove the speech bubble in the top right of every post. I have not done anything about this so far.

3. Remove the border around post images. I did find some post about it, but it didn’t work for me.

4. Is there any way I can align everything? Right now the menu and the boarder is far more to the left that the posts. I don’t know how to explain this properly, so I hope you understand.

There is sure more to come. I’m trying to search on the forum to fix thing for myself, but I do not succeed in every attempt.

Thank you for any help!
