Many people like to use textboxes in Word to highlight certain sections of a document, the problem is text boxes aren’t accessible.  However, if you want the same look you can modify an existing style within Word for the same effect.  Select the section of text you would like highlighted and boxed.  Goto the home tab, and in the style menu select “intense quote”.  At first this will make the text blue, italicized, and between two blue bars.  Now right click on “intense quote” in PC or control click on a Mac to modify this style. You can change the text to black, and bold, or whatever you would like.  At the bottom of the window you can select format and then select borders.  Now you can choose a box and you’ve just achieved the same look, but accessibly.   You can modify it to achieve various looks.  You can do these modifications for this document only or save for future documents.
