Awareness: Headings provide content structure to facilitate the screen-reading of a slide
Solution: Insert a new slide before Slide #1. Click above Slide #1 and a red line will appear. On the menu select Insert. Click New Slide and pick any one with a Title.
A new slide will be inserted. The section that is corresponding to the title on the slide would also appear. Right click to copy this title box. Go to the Slide #2 (the original Slide #1 before inserting a new slide) and paste the box. The title box will appear in front of the original content.
Enter the title for Slide #2. Make appropriate adjustment, if necessary, to the content so that it is readable. Repeat the process until all slides in the document have an appropriate heading. At the end, delete the Slide #1 that was added to provide the title feature. Save the document.
The presentation contains images that are missing a description
Awareness: A clear description for an image allows audience to better understand the content
Solution: Find the slide that contains such an image. Right click the image to Format Picture...
Click on the Size and Properties icon. Enter a meaningful Title and a thorough Description for the image. Save the document.
The presentation contains tables that are missing headers
Awareness: The top row of a table typically helps identify the content of the columns
Solution: If the top row is not the labels, insert a row and enter identifiers. Click anywhere on the table. Table Tools tab appears on the menu.
Click on Design and check the Header Row Box. Make sure that the data remain visible. After the Header Row box is checked, the font color could be changed. Such occurrence is due to the Table Style chosen when this presentation was originally created.
