Icons are a powerful tool to express something without words, indicating actions or area’s that should require the user’s attention, for example.
To provide you with a wide range of icons, Font Awesome is included in the theme and implemented in components.
To use these icons, simply create an element as follows:
<i class="fas fa-star fa-lg"></i>
.fas stands for Font Awesome solid, for all solid icons.
To include icons of brands, such as Github, use
<i class="fab fa-github fa-4x"></i>
A great variety of options is available to customize your icons, such as size, rotating, stacking, and more.
You can find these on the Font Awesome documentation
