The design signature type has a shadow.

1. Select a font, right-click the window, and then click the font.

2. In the first case, in the old version, the "shadow" was directly ticked off in the "Effect" column of the "Font" window.

3. In the second case, for the latest version, click the text effect bar in the lower left corner of the font window to open a window "Format Text". Click the effect in the rich text window, and the first drop-down bar is displayed as "Shadow".

4. Click the box to the right of "Shadow" and a drop-down box will appear. Click on "No Shadow" at the beginning.

5. Finally, remember to click OK in the font window.
