Custom fonts not rendered in bold or italic in IE - html

Question

I'm trying to load local fonts with custom names. Everything works perfectly in all browsers except IE, as always. The font isn't being rendered in bold or italic. I can't seem to understand what I'm doing wrong here.
Here is a demo:
http://jsfiddle.net/maitreyjukar/5ga5k2oa/
I am loading the font using the following CSS
#font-face {
font-family: k_Arial;
src: local("Arial"),
local("Helvetica"),
local("sans-serif");
font-weight: normal;
font-style: normal;
}
for all combinations of font-weight and font-style.

Answer 1

This is not only not an IE-specific issue it doesn't work on other browsers like Firefox.
Just write one font-face Rule istead of four like this:
#font-face {
font-family: k_Arial;
src: local("Arial"),
local("Helvetica"),
local("sans-serif");
}

Answer 2

It's not an IE-specific issue - I'm on Firefox 38 and it doesn't work here either...
local sources are usually used to search on a user's machine before pointing to a URL, in order to speed things up.
However, you seem want to solely use locally installed fonts with a certain fallback order.
To achieve this, you could simply do the following:
body {
font-family: Arial, Helvetica, sans-serif;
}
.bold {
font-weight: bold;
}
.italic {
font-style: italic;
}
Bonus tip: Combine the bold and italic classes and you don't need an additional class bolditalic.

Answer 3

you can define your font like below example, this will work in all the browsers.
#font-face {
font-family: 'ProximaNovaRegular';
src: url('../fonts/ProximaNovaRegular.eot');
src: url('../fonts/ProximaNovaRegular.eot') format('embedded-opentype'),
url('../fonts/ProximaNovaRegular.woff2') format('woff2'),
url('../fonts/ProximaNovaRegular.woff') format('woff'),
url('../fonts/ProximaNovaRegular.ttf') format('truetype'),
url('../fonts/ProximaNovaRegular.svg#ProximaNovaRegular') format('svg');
}
