Themes are expansive customizations that change multiple elements of the style of your forum design, and often also include additional front-end features.
Larger and more encompassing than theme components, themes have the ability to significantly change the look and layout of your forum.
Depending on which elements are already included in a theme, it is also possible to combine other theme components with them to further individualize your site.
