@suraj deleting the node_module folder from project. and instaiing `npm install` does it will help. or any removing platform and adding platform does it will help ? — hybrid Dev, May 01 '17 at 14:00
try resetting node_modules..I dont see anything wrong with the code though — Suraj Rao, May 01 '17 at 14:01
@suraj resetting means deleting it and adding it again right ? — hybrid Dev, May 01 '17 at 14:03
yes.. delete and `npm install`.. have you set any content security policy? — Suraj Rao, May 01 '17 at 14:04

The squares probably signal that the font is either not getting loaded properly or the browser is trying to use an alternate font face. An easy way to verify that the ionicons font is being loaded at all is to check your sources in Chrome Dev Tools. Mine looks like this: http://localhost:8100/assets/fonts/ionicons.woff2?v=3.0.0-alpha.3

If you don't see that file (or something similar) getting loaded then there's no font to render.

The ionicon font should get loaded automagically if it's referenced in your package.json file and exists in the node_modules folder. After verifying this, if the font is not getting loaded, make sure you don't have any other CSS imports/variables that are overriding the ionicons font import. e.g something like this:

 * {font-family: 'Lato' !important;}

The above will result in the ionicons font never being loaded because Lato is specified to be used for all glyphs, overriding the earlier @ionicons import.
