Do Not Make Meta Tags Like in WordPress

[Hashigato]

Hello friends, on my WordPress site, the title section is in the format of "slogan - site name" such as "WordPress Help Blog - Wpyardimi.com." However, it is different on my DLE site where I specify keywords, description, and title in the panel, and only the "site name" appears in the title section as "Wpyardimi.com." To make it similar to WordPress, where it shows "Article Title --- Site Name," which file should I edit to achieve this on my DLE site, both for the titles and in the articles themselves?
