Bold not rendering Ubuntu font

I don’t seem to be able to get Ubuntu font to show its bold. If I style up text as bold it simply letterspaces the text.

Any ideas anyone?

Right now Ubuntu fonts are taken from Google Fonts Library and it uses default font-width, which is 400.

Here is how it is defined:
wp_register_style( 'google_font_ubuntu', '' );

Instead you have to change it to code like this

wp_register_style( 'google_font_ubuntu', ',700' );

and you will get font width of 400 and 700. You can also add italics, etc. Just look for reference inside Google Fonts Library

Oh, I’m sorry Aigars, I didn’t realise you’d replied to this! Thank you for the answer. Do I add this to my functions file?

Yes, you can also setup it via Child Theme functions.php or you can tweak current value which is already defined via them folder - library - functions - functions.php.

perfect, thank you!
