Instead of manually changing aspects such as heading size, colour, and font, modify all headings classified under that specific heading type you would like to edit. To modify headings:
In the Home tab, you will see an area called styles Styles where all of the different heading types are displayed.
Right-click on the heading you would like to edit and select modify.
A window appears with options to change the font type, size, colour, etc.

More options under the Modify tab

Shortcut key: allows you to customize a specific command by adding keyboard shortcuts.
Text Effects: allows you to modify the text for that specific heading by using effects such as text fill and text outline.
Columns and page section breaks
In accessible documents, using columns is a good way to create a table format that is accessible.
...
Highlight the text you would like to add a border around.
In the Home tab, click on drop-down menu to view the border options.
Select any of the given options (e.g. all borders, outside borders).
To modify borders, click on the same drop-down menu and select Borders and Shading.
Go through the tabs to change the border type and to fill/shade in the borders
...
When you are modifying borders and shading, you will see an option that says Apply to: which allows you to select if you want the changes applied to the whole document or a specific section of the document.
The Developer tab
The developer tab provides more specific options such as checkboxes and date fields. If the developer tab does not show up automatically in your MS Word Ribbon:
...
You will see options for Rich Text Content Control
or Plain Text Content Control 
which allows you to add an accessible text box for writing in. Example: If you are making a form that someone is filling out online, you can select either the Rich Text or Plain Text Content Control, and a text field will show up that allows the individual to click and write in the box that looks like this:
Another option that is given is the Check Box Content Control
which allows you to add a checkbox to your document.
Example: If there is a “circle yes or no” question on a document, use the Check Box Content Control instead to make it accessible:
Have you received all the required training?
Under the Developer tab, there is also an option to use the Date Picker Content Control which allows you to insert a date picker to your document.
Example: Perhaps you are asking someone to fill out their birthday online. Instead of having them type out the date manually, the Date Picker Content Control allows them to select the date by using a calendar provided:
There are other Content Controls provided in the Developer tab and by hovering over them, it will give a brief description of what they are and what they are used for.
...
The blue boxes in the pictures below represent form fields. Sometimes extra form fields can be accidentally added, and can look something like this:
The picture below represents what a correct form field should look like:
To get rid of extra form fields, click on the form and then click the 3 grey dots and hit Delete. This will delete the entire form field, so you must go back in the Developer tab and re-add whichever Content Control was in place.
Using Alternative text
When any image/snipping is used in a Word/PDF document, it is important to ensure that the information you are trying to convey can be interpreted by those who may not be able to see the image.
...
Right click on the image/snipping in your document.
Click on the Format Picture button.
In the right-hand menu that pops up, click on the Layout and Properties symbol.
Select Alt Text.
In the Description field, describe the image/write the alt text.
Once you are satisfied with your alt text, click the exit button to return to your document.
Note:
The alt text will automatically save once you exit out of the format picture window.
Checking accessibility
Microsoft Word has a built-in accessibility checker that allows you to review your document and ensure that it is accessible for users who have disabilities.
...
If there are any accessibility issues in your document, a tab on the right-hand side will appear telling you what the problem is. Example:
When there are no accessibility concerns, the Accessibility Checker displays as follows:
Making PDF files fillable
Adobe Acrobat Pro DC allows you to edit files by making them accessible to fill out, once they are converted from a Word Document format to a PDF.
...
After you are finished with your Word Document, click File in the MS Word Ribbon.
Click Save as Adobe PDF.
If you haven’t already saved your Word Document, a message will pop-up that says that your file must be saved before creating a pdf. Click Yes.
It will then prompt you to name your file. Name your file and choose where you would like to save it to, and then click Save.
Another window will pop-up and will ask you to do the same, but this time it will save as a PDF file instead. You now have two copies of your file. Click Save.
...
If you have already added Textboxes or Content Controls in your original Word Document, you will need to Delete them (either in Word or Adobe Acrobat Pro DC) in order to create fillable replacements.
To delete Content Controls directly in Adobe:
Click on the Tools tab at the top of your Adobe PDF file.
Look for the Edit PDF tool and click Open.
You can now erase any of the Content Controls you previously added in your Word Document. Click on the writing (e.g. “Click here to enter text.’”) and erase the text you wish to delete.
Once you have finished erasing all of the Content Controls, click on the Tools tab to return to all the tool options.
Click Open on the Prepare Form tool, to return to your fillable PDF. (It may ask you to save your file before opening the form).
You will now notice that there are either blank spaces or a Text Field automatically added beside each of your fields to fill out. If a Text Field does not automatically show up, you can manually add a Text Field in Adobe to replace Content Controls.
To add Text Fields:
Right-click on the area in your PDF where you would like to add a Text Field.
A list of options will display. Select Text Field.
Drag your mouse to move the Text Field to the size you would like.
To change the font size, colour, and so forth, right-click on the Text Field and select
A window will then pop-up where you can go through the tabs such as appearance, to change the font, size and colour.
...
In the top-right corner you will see a Preview button. While you are editing, at any time you can click on that button to test or view what the file would look like outside of edit mode. For instance, if you added a Text Field, by clicking on the Preview button, you can type into that field to test if it is working. Once you are done, click the Edit button to return to editing the file.
Save your file once you are finished with it, by clicking on the File tab at the top of the document and then by selecting Save as. Name your file, choose where you would like it saved and then click Save.
Important things to remember
There are some important considerations to keep in mind while writing the content of your Word/PDF document:
Make sure that acronyms and abbreviations are defined on the first use. Once it is introduced the first time it is used, you can use the acronym/abbreviation throughout the rest of your content without writing the full name.
Example: “The Arts computing office (ACO), provides students, faculty and staff with computing accounts, computer and lab printing access, technical support and more.”
Make sure text follows sentence casing. Only the first letter of the first word should be capitalized according to accessibility and style guide compliance.
Example: For a title-“Accessible checklists, files and documents”.
