I did my best to try to use bootstrap locally with flask on a computer (without internet connection). My folders are like that : Templates
-layout.html -bootstrap -css -bootstrap.min.css -js -bootstrap.min.js -jquery-3.2.1.slim.min.js -popper.min.js And in my layout.html file, I use bootstrap with these lines :
<link rel="stylesheet" href="bootstrap/css/bootstrap.min.css"> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1" in the head tag and
<script src="bootstrap/js/jquery-3.2.1.slim.min.js"></script> <script src="bootstrap/js/popper.min.js"></script> <script src="bootstrap/js/bootstrap.min.js"></script> in the body tag. If I launch just this html file, the bootstrap is working but if I use this template in my app.py file like that :
@app.route("/") @app.route("/home/") def home(): return render_template("layout.html") The bootstrap isn't working... Thank you in advance for your help.
