Remove the indentation on the site

Hi Oleg. Is Customizer > Layout > Content Layout set to "One Container"?

Yeah ... I knew but had forgotten!

Glad you got it fixed.

I'm sorry, but I have to ask for help again. I found that a content is also contained an empty strip. How can I remove it?

Part of it is in the theme, part of it is Visual Composer. Try this css:

article.hentry, .entry-content .vc_row {
    margin-bottom: 0;
}

Yes, it helped. But I found another problem. Your last tip is not working as it should.

Oleg - I don't see the sample page you showed in your post. Is it still available? Or were you able to remove the spacing?

No, I have not solved the problem. I returned to the place of the page: http://olegte.bget.ru/sample-page/. Please log in to the control panel: http://olegte.bget.ru/wp-admin/, login: demo, password: demo.

Give this css a try:

.one-container .inside-article {
    padding-bottom: 0;
}
.entry-content {
    margin-top: 0;
}

Yeah, great, thanks!
And finally, even the part to the administrator.

I discovered another problem. When one container, the background image is not displayed in block with the contents.

Hi Oleg,

For the first issue, you'll need to remove the footer meta:

footer.entry-meta {
      display: none;
}

For the second issue, try removing the content background color in "Customize > Colors > Content Colors" - simply delete the value from the "Content" area - it looks like the white is just covering the background image.

Let me know :)

Tom, footer meta - great.
Removing the content background color in “Customize > Colors > Content Colors” - there is no such settings. I do not have add-on "Color". I bought add-on "Background" to make a transparent PNG background content.

In that case, try this CSS:

.inside-article {
      background-color: transparent;
}
