How do I apply grid overlays when aligning elements in a poster?

Example Technique:

• Step 1 – Choose a grid system that suits your poster's purpose, such as a 3x3 or 4x4 grid, depending on the complexity of the content.
• Step 2 – Align key elements like titles, images, and text blocks to the grid lines to create a cohesive structure.
• Step 3 – Ensure consistent spacing and alignment by checking that elements are evenly distributed and visually balanced across the grid.
