By default, your Twitter feed should inherit the font from your website. If this isn’t the case then it’s possible that something in the theme is preventing this from happening. An issue that we’ve run into before is that <code> tags are added into the plugin HTML by either the theme, another plugin, or perhaps even the shortcode being wrapped in code tags in your page editor. To fix this;
1) First – go to your page editor, click on the ‘Text’ tab in the top right of the editor box, and check whether the shortcode is being wrapped in <code>, like so: <code>[custom-twitter-feeds feed=1]</code>. If it is, then remove them.
2) Se isto não resolver o problema, tente adicionar o seguinte à secção CSS personalizado do plug-in(Twitter Feed > Definições > Feeds > CSS personalizado):
#ctf code { font-family: sans-serif; }
Pode substituir a font-family por qualquer tipo de letra que o seu tema esteja a utilizar.
Nota: também pode definir tipos de letra personalizados do Google no seu feed seguindo as instruções nesta FAQ
