Here’s another helpful tip when working with text boxes. This tip comes into play when you’ve defined a fixed-sized text box (e.g., you’ve drawn the text box in the size you want it to remain). Now it used to be that you could ‘shrink text on overflow’, which is no longer an option and one that I wouldn’t recommend from an accessibility perspective. Why? Because the text could shrink to less than 12pt font size which would no longer be WCAG compliant.
Now, when you’re working with a fixed-sized text box, you can choose between two options: 1) allow a scrollbar, or 2) allow the text to overflow the bounds of the text box…in the latter, you would likely then have to go ahead and add a scrolling panel and it would be a whole, unnecessary to-do. Here’s what I would recommend doing.
