What does a placeholder in a document signify?

A placeholder in a document signifies a temporary text or image that is meant to be replaced or completed later. Placeholders are often used during the drafting process to indicate where specific content will eventually be inserted. This allows the document creator to structure the layout and flow of the document without having all the final content ready. By using placeholders, authors can focus on the overall design and organization first, ensuring that the document has a cohesive format before adding the detailed information. This is especially useful in collaborative projects where different team members may be responsible for adding specific sections at different times.
