How to change all default font, using google font early access?

Hello

I have foreign languages on my website. Therefore I want to change all default font (website header, blog title, menu, blog & page’s title and content, etc.)
I want to use Google font earlyaccess https://www.google.com/fonts/earlyaccess

I’ve added below code to custom css but nothing changed. Can anyone guide me through this? Thanks a lot!

@import url(http://fonts.googleapis.com/earlyaccess/cwtexhei.css);
#site-title a {
	font-family: 'cwTeXKai', serif;
}

body,input,textarea,article {
	font-family: 'cwTeXKai', serif;
}

.post-title {
	font-family: 'cwTeXKai', serif;
}

.blog-description {
	font-family: 'cwTeXKai', serif;
}

.blog-title {
	font-family: 'cwTeXKai', serif;
}

.blog-title a {
	font-family: 'cwTeXKai', serif;
}

h1, h2, h3, h4, h5, h6, p, blockquote, address, big, cite, code, em, font, img, small. stritd, body {
	font-family: 'cwTeXKai', serif;
}
