The provided article appears to contain only technical CSS styling code rather than actual journalistic content. While the title suggests an article about Werner Jeker creating a memory of Lausanne through posters, the body text consists entirely of web development code including CSS styling rules, HTML elements, and technical specifications.

Without access to the actual article content, it is impossible to provide a complete and detailed rewrite that would include information about Jeker's work, his artistic approach to poster design, or his connection to Lausanne's cultural memory.

To properly rewrite this article, the original French text content would need to be provided instead of the technical code that appears to have been mistakenly included in the source material.
