W3.CSS DEFAULT COLORS
The w3.css stylesheet has pre-styled colors that can be applied to elements and containers such as bars, divs, borders and text..
Each container shows the colors with text in the color it appears when w3-color is used as a class.
These classes can be edited on a downloaded copy of the w3.css stylesheet.
Add a splash of color with a button or alert. This button is a w3-CSS modal often used to announce events or an account sign up prompt. Modals normally pop up a few seconds after the page loads.
