i have 3 routes and one of them hasnt css style.
actually /en_blog/sd and /en/ work fine.
but  if i try this route /en/blog/ template will show without any style.
how i can fix it?
this is my flask view code
@core.route('/en/')
def en_home():
    return render_template('en_home.html')
@core.route('/en/blog/')
def en_blog():
    return render_template('en_blog.html')
@core.route('/en_blog/')
def en_siteintroducing():
    return render_template('en_blog.html')
