Typography style in View app-doesn't work

It's hard to see where things are going wrong for you without seeing your actual configuration. But here's what works for me:

1) Upload the font files to the project. I'm using OpenType fonts, and they seem to work fine.

2) Add @font-face specifications to the top of your Application CSS file. These can be a little tricky, make sure to get the parameters right, especially the src property and all its components:

@font-face {font-family: 'Montserrat'; font-style: normal; font-weight: 400; src: local('Montserrat Regular'), local('Montserrat-Regular'), url(#{$resources}/Uploaded/Montserrat-Regular.otf) format('opentype');}
@font-face {font-family: 'Montserrat'; font-style: normal; font-weight: 500; src: local('Montserrat Medium'), local('Montserrat-Medium'), url(#{$resources}/Uploaded/Montserrat-Medium.otf) format('opentype');}
@font-face {font-family: 'Montserrat'; font-style: normal; font-weight: 700; src: local('Montserrat Bold'), local('Montserrat-Bold'), url(#{$resources}/Uploaded/Montserrat-Bold.otf) format('opentype');}

3) Reference the font files in your style classes as needed

.eacfont { font-family: Montserrat, "Courier New", serif; }

The font shows up as expected in View:
