The theme is mobile responsive so it will shift the elements around depending on the screen.
The customizer has been updated so you have a few more options there but ensure that you have installed any pending updates available via Dashboard > Editor.
I would have to see this issue, can you add a link to your site and an image of that issue?
You can use the following CSS code to remove the bars by going to Appearance > Customize > Additional CSS and pasting it there.
You need to ensure that each post has a featured image assigned to it, simply edit the post and on the right hand side there should be the featured image section.
YOu can edit it via Appearance > Customize > General Options > Footer or remove it with this CSS:
Reg question nr 5 link is still the same as above but here is also screenshot (11.43)
Reg nr 7 I tried to put in extra css with the code you gave me but it did not work. In the general options view I was not able to remove it as well. Also sending a screenshot for this (11.47)
Additional question, how do I chanhe font and colour to headlines on first page as well as H1 on the blog. Or maybe that is the same all over haha.
