How to change class in modx?

Question

MODX

The template template has a div with the class example.
I apply this template to several pages, but the fact is that on different pages I need a different class for this div (somewhere example, somewhere bla-bla, not the point). Please tell me how you can make a universal solution so that, for example, you can write the right class on the right page and it will automatically be substituted into the template.
PS in fashion is not strong at all.

Answer 1

Answer 2

Check by template id and substitute your classes.
