Zoho Writer lets you add different watermarks to specific pages or sections of your document using text boxes. You can place a text box behind the text on a page or in a section’s header to mark only the content you choose, such as “Draft” or “Confidential.”
Click Insert > Text Box to insert a text box anywhere in your document.
Add the desired text, format it as needed, and rotate it with the cursor if you want the watermark to be diagonal.
In the Text Box options pane, set the wrap type to Behind Text. The text box will now appear like a watermark in the specific section of the document.
Make sure your document is divided into appropriate sections.
To add sections,
Place the cursor before the page after which page orientation has to be changed.
Insert Tab → Page Break → Section break → Next Page , to insert a section break.
Now insert a text box by clicking Insert > Text Box.
Add the desired text, format it as needed.
In the Text Box options pane, set the wrap type to Behind Text. The text box will now appear like a watermark in the header of the document.
