The style attribute is used when we want to declare the CSS style inline. The styleClass attribute is used when we want to use a predefined style in a CSS style sheet or inside a <style> tag in our page.

The following markup illustrates using the styleClass attribute to alter the style of error messages; it is a modified version of the input page we saw in the previous section:
