For some reason on just one of my pages I get an empty space that I believe is generated by the bootstrap's library.
I am including the page into a section <section class="container col-md-8">
from another page, and the empty line shows up at the start of the section. On the F12 inspector it is seen as " " and when I select to edit it as HTML, a small red dot appears. What might be the reason for it ? And it is generated only on this page, every other included page in the section is fine.
Here are some screenshots:

Your file is encoded in
UTF-8 with BOM
, change the encoding toUTF-8 without BOM
So it relates to the Byte Order Mark rendering in Chrome, and is a similar issue to:
Invisible character rendered between Twig includes
Chrome apparently shows those dots also in cases like zero-width-space characters, such as in the jsfiddle here
