How to set the design to the page of a certain tag?

Question

DLE

I want to bring to mind pages with tags on the site so that something like what is on Tj https://tjournal.ru/category/deletefacebook
That is, when you click on any tag from the DLE tag cloud, the tag itself was written on the page , and if necessary, some special block displayed in a specific tag.
For example, the {tag-title} tag will display the tag name on the page https://site.ru/tags/any+tag
.
