问题
In my site I don't have any LESS code or such set up but there seem to be some CSS LESS generating in my site when I check in FireFox inspector but I don't know the cause of it. Things are being generated are like:
grid-framework.less | normalize.less | table.less | scaffolding.less
I can't unfortunately post all the code because is huge. So here are the CSS includes
<link href="css/bootstrap.min.css" rel="stylesheet">
<link href="css/myStyle.css" rel="stylesheet">
<link rel="stylesheet" href="css/font-awesome.css">
Script includes
<script src="js/jquery-3.1.0.min.js"></script>
<script src="js/bootstrap.min.js"></script>
<script src="js/lib/screenfull/screenfull.js"></script>

It's coming from your .map file that LESS/SCSS/SASS creates once compiled. The purpose of this file is to give the original file location of the CSS styles for easier debugging and development.
You don't need it if you aren't using a compiler, but it is nice to have in the event you are.

It's coming from a sourcemap reference at the end, which would look like this:
/*# sourceMappingURL=bootstrap.min.css.map */
The file it links to will contain encoded references to these less files.
Feel free to remove both the above line with the sourceMappingURL and the .map file it refers to, from your local folder.
