Hi delinea
You can replicate it by changing the base font in JA Focus template.
Open the file: /templates/ja_focus/less/variables.less
Look for this code:
//@font-family-sans-serif: 'Heebo', sans-serif;
@font-family-sans-serif: "Roboto", "Helvetica Neue", Helvetica, Arial, sans-serif;
@font-family-serif: 'Noticia Text', serif;
@font-family-monospace: Monaco, Menlo, Consolas, "Courier New", monospace;
@font-family-base: @font-family-sans-serif;
Change the font-family-sans-serif to Roboto as above
and compile less to css: http://www.t3-framework.org/documentation/bs3-configuration#compile-less
REMEMBER to backup all CSS files before compiling.
