Editing Forms Accessibility in Adobe Acrobat (section)

=== Checkbox options ===

==== Checkbox appearance ====

Checkboxes seem to constructed with a border, padding inside the border, and a fill area. 

When the checkbox is selected, there is always padding between the border and the box used to indicate that the checkbox has been selected. 

The style of the check mark can be controlled with '''Properties''' > '''Appearance''' tab > '''Text''' > '''Font Size''', which will control the size of the box displayed when the checkbox is selected, and ''Properties''' > '''Appearance''' tab > '''Text''' > '''Text Color''' which will control the color of that box. 

==== Checkbox groups ====

It doesn't appear possible to group checkbox form fields together. If they have the same '''Name''' they will be have like radio buttons, i.e. only one option out of all options with the same name can be selected at one time.
