When I tried serving dynamic CSS (I wanted to dynamically control
colors, fonts, etc), I had to do some work to get the result served as
text/css (which is necessary). I ended up hacking that (and some other
header stuff, like caching) in the controller, but I suppose it could
happen in the view.
I notice that there's no generic.css.
I have a controller, css.py, that looks like this:
import time
from gluon.storage import Storage
def __cssheaders():
'''
edit default response headers for CSS
serve text/css with limited caching
'''
response.cookies = Storage()
response.headers['Content-Type']='text/css'
response.headers['Cache-Control'] = 'max-age=3600, must-revalidate'
if 'Last-Modified' in response.headers: del response.headers
['Last-Modified']
if 'Expires' in response.headers: del response.headers['Expires']
if 'Pragma' in response.headers: del response.headers['Pragma']
def xxx():
'''
app/css/xxx.css
set fonts and colors to be substituted via xxx.css view
'''
__cssheaders()
font_serif = 'cambria, georgia, "times new roman", serif'
font_sans = 'corbel, "Helvetica Neue", Helvetica, Arial, sans-
serif'
return dict(dark_color="#8e1650", second_color="#635e54",
light_color="#e9e7de",
accent_color="#edab05", flash_color="white",
flash_background="#8e1650",
body_background_color="#e8e8e8",
content_background_color="white",
font_body=font_serif,
font_logo=font_sans,
font_head=font_sans,)
