Using the 'all' selector

When I use the 'all' selector

@media all (max-width: 960px) {

The CSS decleration does not work ??

When I take the all out

@media (max-width: 960px) {

It works fine.....

Why is that?

Venkataraman is right- you need an 'and' before your 'all'. The @media selector always needs an 'and':

@media all and (max-width: 960px) {}

@media screen and (min-width: 10px) {}

@media print and (max-width: 90000px) {}

I hope this helps!

you are missing the 'and', its @media all and ....
