Hello @user544 and @DOMINICANCOD. Welcome to the best Community in the world 
!
I am happy to provide you with a detailed CSS code that allows to change font size, family and color:
/* FAQ title font family, size and color */
.es-widget-title {
font-family: ‘Lora’, serif;
color: #009EE0;
font-size: 30px;
}
/* FAQ questions font family, size and color */
.eapps-faq-content-category-item-question-text {
font-family: ‘Lora’, serif;
color: #000;
font-size: 16px;
}
/* FAQ answers font family, size and color */
.eapps-faq-content-category-item-answer-text {
font-family: ‘Lora’, serif;
color: #000;
font-size: 16px;
}
Please add this code to the Custom CSS section on the Appearance tab in your widget’s settings and let me know if it helped.
@user544 I see that our support agent Natalia has already contacted you and our devs are in the process of creating a special CSS code for you. They’ll keep you updated
