Applying a Design Template to All Slides in PowerPoint

1. Open Your PowerPoint Presentation
   Launch PowerPoint and open the presentation to which you want to apply a design template.

2. Access the Design Tab
   Navigate to the 'Design' tab located on the Ribbon at the top of the window. This tab contains various tools for customizing the appearance of your slides.

3. Choose a Design Template
   In the 'Design' tab, you will see a gallery of design templates. Browse through the available templates to find one that suits your presentation.

4. Apply the Template to All Slides
   Click on the desired design template. The template will automatically be applied to all slides in your presentation. If the template does not automatically update all slides, you may need to apply it manually by selecting each slide and applying the template.

5. Customize the Design (Optional)
   If you want to make further adjustments to the design, you can use the 'Variants' options within the 'Design' tab to modify colors, fonts, and effects. You can also use the 'Slide Master' feature for more advanced customization.

6. Save Your Presentation
   Once you are satisfied with the new design, save your presentation to ensure that all changes are preserved.

By following these steps, you can efficiently apply a design template to all slides in your PowerPoint presentation, ensuring a consistent and professional appearance throughout your slides.

Additional Tips:

• Preview Templates: Use the 'Design Ideas' feature to get suggestions and preview how different templates will look with your content before applying them.
• Save Custom Templates: If you frequently use a particular design, consider saving it as a custom template for future presentations.
