I usesd external bootstrap and css to create a sytlish menu bar but the bar doesnt appear on mobile device. it just displays an empty space where the menu is supposed to be. Oh the same with logo.

It has to do with the way you implemented it.

If you are referring to the Bootstrap framework, then follow this link:

Of course you also need to implement mobile css to display well in mobile devices, and can make use of the @media rule to customize according to screensize:

Is it too big to fit on the screen?

It could be your Glyphicons isn't setup correctly. Check the URL in the bootstrap.css leading to the Glyphicon file and that the files are actually in the directory.

it is large according to the screen.

The OP seems to have left the building a month ago. Unless (s)he comes back with more info, pointless floating this thread to the top of the forum - so let's stop posting here.
