* Arguments: |
| 1808 |
* - instance [string] - UD plugin|theme's slug. E.g.: wpp, denali, wpi, etc |
| 1809 |
* - element [string] - specific element in template which will use the current classes. |

* Element should be called as {template}::{specific_name_of_element}. Where {template} is name of template, |
