I've run into trouble using my own stylesheet while using Bootstrap. This is the beginning of my header.php (which I import in the beginning of index.php):
<html>
<head>
<link href="includes/css/bootstrap.min.css" rel="stylesheet">
<link href="includes/mystyle.css" rel="stylesheet">
EDIT:
I've found out that for some reason I can include the file if it is in the same folder by: <link mystyle.css" rel="stylesheet">
but if I move the folder the includes folder and do as I did in the beginning, for some reason it won't import the stylesheet. Very weird...
