Best way to color change text box and make it stick once you click out of it.
I have a chart that people will fill out with custom text. However, not every box in the chart will be completed. What is the best way to have the text boxes that are completed change colors so they stand out once you click off of them? I can get the boxes to change color when you type into it but it won't stick once you click into another text box. I've tried various validation statements, but nothing seems to work. I'm at a loss. Do I need an if than statement? I'm not the best at JavaScript. Thanks in advance.
