Bootstrap theme not as wide as parent container

I need help with bootstrap container and row width.

I have created a container and a row inside it. I have everything inside the row, but for some reason content sizes are different as displayed on jsfiddle and image preview.

<!DOCTYPE html>
<html lang="cs">
    <head>
        <title>xGhost.cz | Československý Gamehosting.</title>

Image preview

On the image you can clearly see, where the spaces are. It all should be aligned from side to side inside the container. Logo column width is missing a few pixels on the right and the two boxes in the bottom are not touching the sides of parrent container.
