wps method of making Template:
Before you make a ppt template, you should first select the material, for example, you want to download or use Photoshop yourself to make a picture, to do ppt background
Open PowerPoint, find it in the toolbar, view options, click Enter, and we'll see all the apps under the view options. We choose the slide master.
To add a background picture, in the blank space of the master, right click, pop-up option box, we click on the open background. Action as shown in the following figure. We can do our own background.
Then we can set up the text-editing bar in our template. We can change the font, the position of the caption and so on.
Add a logo on the template, if you want to represent the school or company to give lectures or report work, may be used, in the PPT to add the school badge, or the company's logo.
The final step is to save the template, or maybe all the work you've done is in vain. When you save, you need to keep it handy for your memory.
