Customizing the Footnote Area
You can customize the size and appearance of the footnote area using page style settings.
From the Format menu, choose Styles and Formatting.
Click the Page Styles icon at the top of the Styles and Formatting window.
Right-click a page style to which you want to customize the footnote style and click Modify.
Click the Footnote tab.
Select your preferred settings. In general, you should set your footnote area not to exceed the page area. If you choose to set a maximum size for your footnote area you risk having Writer automatically push a footnote reference to the next page.
Click OK.
