Can you help me?

Hi,
You are really incredible
How you want a answer ?
It's a CSS problem, so this can only be solved on checking your live site. SO please provide a URL if you need a right answer.

Sorry about bothering you with my 'basic problem' questions.
I'm a really very beginner and unfortunately, my site is only on my localhost.

I thought anyone of forum members have had same issue earlier and can give me a hint, in which css file should I look after the issue . . .

You use non standard template, so the problem come from your template.
So it cannot be solved without having access to the page(or with some luke). The problem can be a container margin or padding problem. And no one can know the  rule to apply only with a screenshot.
SO use your browser inspector (f12 with a PC computer) and try to live change your CSS

Thanks for your response.
I use only the common templates (protostar, etc.)  The only what I changed is the body background color.
K2 and VM templates are as I installed these.
Anyways, I'll try to find the css file which cause this problem. Thanks
