Can't load bootstrap css file

Question

I'm creating a django project in pycharm and I'm trying to use bootstrap blog example( https://getbootstrap.com/docs/4.4/examples/blog/ ). I came across a problem: bootstrap.min.css file is not working properly, when I link it like this it works properly,

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous">

but when I download this file then save it in my_app/static/my_app/bootstrap.min.css and link it like this,

<link rel="stylesheet" href="{% static 'blogs/bootstrap.min.css' %}" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous">

it doesn't work, the django development server is properly loading the css file

[14/Jan/2020 19:04:26] "GET /static/blogs/bootstrap.min.css HTTP/1.1" 304 0

but it just doesn't have any effect on the site apperance, the blog.css file does have effect as I can see fonts and a few thing change but the bootstrap.min.css file just doesn't.

Answer 1

Try to log your path if it return where your bootstrap.min.css file exists. Then check if your browser's cache is clear if not then give it a try.

Answer 2

I checked the console in browser, as @tao said, turns out the problem was the

integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh"

in

<link rel="stylesheet" href="{% static 'blogs/bootstrap.min.css' %}" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous">
