Hi there,

open style.css and add

@import url(https://fonts.googleapis.com/css?family=Work+Sans);

at the beginning of the file.

then specify the font family to the elements you wish to apply to

h1, h2, h3, h4, h5, h6, .item-title, .post-title, .post-title-no-link, .clapat-counter .number, .p-table-title, .p-table-num, .p-table-num sup{

...

}

and/or

input[type=\"text\"], textarea, .clapat-button, .more, .progress-bar li p, .progress-bar li span strong, .radial-counter input, .menu-title{

...

}

in theme options -> styling options -> custom css

thanks
