We would like to change the background color of the text box so the placeholder text can be seen and read as well as darken the paper airplane graphic on the send button. We tried the CSS below, based on manually changing it in the Google Chrome dev tools. Yet, the colors do not change. Any suggestions would be greatly appreciated. Thanks, John
