Most page and document settings options can be found in the "Page" and "Document" tabs of the context pane. Click on the white background of a page to pull up the Page tab and click on the grey canvas background to open the Document tab. These tabs are similar, but while changes made in the Page tab will only be applied to the selected page, those made in the Document tab will affect every page in the document.
Select a size for your page or document from the drop-down or select "Custom" and manually adjust the width and height of your page(s) in the boxes underneath.
To flip the dimensions of your page(s) 180˚, switch the orientation setting from portrait to landscape or vice versa.
If you check the box next to "Header" or "Footer," an editable region will be added to the top or bottom of every page of your document. The region will be defined by a horizontal dotted line, visible when you hover your mouse over the top or bottom of the page. If you double-click in this region, a black bar will appear across the top of the canvas, and the dotted line will remain selected, indicating that it is in editing mode.
You can adjust this line’s distance from the top/bottom of your document by clicking and dragging the and tabs, or by typing a value into or toggling the arrows next to the "From Top" or "From Bottom" text boxes.
If you want different header/footer settings for different pages, you can select "First page is different" or "Left and right pages are different."
Anything that you put between the dotted line and the top/bottom of the document while in editing mode will become a part of your header or footer. This includes shapes, text boxes, page numbers, and other content. You can auto-fill your header or footer with linked content from the insert tab of the menu bar. See these content options below.
If you select “Page Number,” each page of your document will be populated with the corresponding page number. If you want your page numbers to begin on the second page of your document, make sure to enable "First page is different" in the context pane.
When you have finished editing your header and footer, press ESC to exit editing mode.
To adjust all of the margins of your page or document at once, apply changes to the text box at the top right of this section.
To show the margin lines on your canvas, navigate to View > Show Margins.
If you are in the Documents tab of the context pane, you will see an option to add bleed to your document in the bottom right. Not sure what bleed is? See Page Bleeds to learn all about it.
Change the background's opacity by moving the blue dot horizontally across the "Opacity" bar or by typing a percentage into the box on its right.
In lieu of a solid color, you can create a linear or radial gradient or upload an image to use as your page/document background. See Edit Shape Fill and Edit Image Fill to learn more about these options.
If you are creating a magazine or book, enable this feature to adjust the layout of pages in the canvas to match that of your printed document.
Page Lock: Lock down a page entirely so that edits cannot be made to its content or layout and so that it cannot be deleted, duplicated or copied. Enabling this feature will automatically enable all of the options described below, but you can deselect these options individually to turn them off.
Page Cannot be Deleted: Prevent a page from being deleted.
Prevent Adding Content: Prevent any new content from being added to a page.
Lock Properties and Settings: Lock down all features of a page besides content, including size and orientation, margins, and background.
Guides are another great tool for object alignment. To add a guide to your document, right-click on the canvas and select “Create Vertical Guide” or “Create Horizontal Guide.”
Move these guides across the canvas by clicking and dragging or enable “Lock Guides” to prevent further movement. If you navigate to View > Guides in the menu bar, you will also find options to show/hide, snap objects to, and clear guides.
Show Comments: When this is enabled, a small icon will appear in the top left corner of any object containing a comment. See Sharing and Collaborating with Team Members for more information on commenting.
Show Locking Restrictions: When this is enabled, objects that contain locking restrictions will be marked with a yellow or red outline and lock icon. When this feature is disabled, you must select an object to see these markings.
Show Off-page Content: When this is enabled, any content that is dragged off a page of your document will extend into the grey background. Otherwise, the content will be hidden.
Page Thumbnails: Enable this option to pull up a display of your document’s page thumbnails on the left of the canvas. You can also show page thumbnails by clicking on the arrow at the middle left of the editor.
Context Pane: Enable this option to display the context pane on the right of the canvas.
Show Rulers: Enable this option to display rulers on the top and left side of the editor.
