How do i give a div an element the class silver-background and also how do i define a class named silver-background within the style element and assign the value of silver to the background-color property.

within <style> </style> add the class .silver-background {background-color: silver}. This will make the background silver.
Now assign the class to the <div> element within the Html , just find the <div> and type class="silver-background" ---> <div class="silver-background" >

Thanks, as i reset the code and input it as you stated it works…Thanks again.
