Hi,

Typography is a big part of a design. We strongly recommend to use the default fonts provided by the theme. The theme is fine tuned for these font families (padding, line height, font-weight and text-transform control). If you must to change the fonts you can use one of the plugins available such as Easy Google Fonts or Google Fonts for WordPress.

If you have installed it already - use it as way to load the google font family you want. then assign the font to the portfolio header.

Send us a screenshot with the portfolio header you want to change (so we know exactly what we are discussing about). and wp admin access.
