Hello, it is impossible to change this in CSS. My code changes the headings on the pages. For example, previously on the timeline pages, no matter what you wrote, there would always be the same heading, for example: "Ivan added a message", which is very bad. With the changed code, the heading is generated from the first 70 characters of the text of the first paragraph, so it will be unique. I noticed this solution in one of the social networks, which is very well ranked by search engines.
