Theme development

Hello everyone,
I tried searching the forum but could not find anything.

I have the following problem:
I am trying to create a theme mioo starting from startekit Zen, following a guide found on the internet, but I'm stuck now.
Basically I would just like to put a background on my page, the guide says to edit the file:
background.css ... but I do not own this file.
I then created the file and put it in your info, but does not take the modifications, I tried to insert the code + css file, but the background color never changes.

Hi all

I created a content type called clubs, which shows nodes like:

example.com/clubs/some-name

The breadcrumbs only show

Home / Some Name

How would I inject clubs as a link to this trail?
So the breadcrumbs would look like

Home / Clubs / Some Name

I've done a bit of searching and found this snippet, though not sure how to use it or if this is what I need?

how do I shift my content in the main block to the center more? I would like to have the articles not so close to the side bar and just have articles centered? check it out Libertycabins.com. thank you for your time!

Hey everyone or anyone that can help me.I am managing a new project (which i was brought onto late) this is also my first time dealing with drupal. I have run into a problem where the original developers of this project choose to use the Bootstrap3 theme because its what they were familiar with and my clients had it listed as a possible theme to use. My question I am wanting to better understand is why is bootstrap 3 better than these other themes listed below?

I'm wondering how to adjust when the menu hides and displays the icon? I'd like to make that happen at a wider breakpoint.

Also, while it's closed, I can still see part of the menu peeking out on the left when I drag the viewport a bit larger than a typical mobile size before the menu snaps back into place. I already applied the padding-left:0 fix, and that worked to get rid of the extra space when it's mobile-sized. I want to keep it completely hidden until it snaps back out.

Thanks!

Hey there,

Is it possible (if so how) to use a drupal layout in an external application?

So I have Drupal in http://www.foo.bar and an application in http://app.foo.bar and both should share the same layout, menu and perhaps blocks.

I found out how to render the menu for instance with:
