I have checked external css file doesn't work in Flask framework etc. other SO questions and my original Udemy source tutorial, but I still can't seem to get my Flask Boostrap app. to pick up my custom CSS file.
From base.jinja2 HTML template file:
{% include 'html_dependencies.jinja2' %}
</head>
<body>
Entire CSS test file in Source/static/css/style.css:
body {
background-color: yellow;
}
(This is test file, body does not change to yellow currently, therefore my CSS appears not to be loading.. I don't really want a yellow background if any style police reading!)
Complete HTML Dependencies file below code, which is loading the main bootstrap files fine, my custom CSS is last file, with url_for and static format syntax as I understand should be correct. Maybe I got the order wrong or some interference from one of Bootstrap files here? Also, I have problem with Bootstrap collapsed nav menu not functioning when window minimised, not sure if this is same cause, the standard lines in box icon shows for navigation when window is below cutoff width, but nothing happens when I click on it.:

I'm quite a Bootstrap newbie, any suggestions grateful.
