Don't see a border in PPT

After you use PowerPoint to make slides, you can't see the borders around the objects. The causes of this problem are many, mainly in the following three kinds.

The border function is turned off in 1.PPT, or the color of the border is a problem. To set the border color, select the object First, and then click Line Color in the drawing, and then press the next Triangle button to select a different color border color.

2. If the object adds a three-dimensional effect, the border disappears.

3. If you add a emboss or sculpture effect to an object, it can also cause the object's border to disappear.
