You can specify the background color of an element using a valid color name (e.g., “red”), a HEX value (e.g., “#ff0000”), an RGB (red, green, blue) value (e.g., “rgb(255, 0, 0)”) or an RGBA (red, green, blue, alpha) color value. Here are some examples:
<div class="demo-container">
<p>background-color: #FFFFFF;</p>
<p>background-color: rgb(255, 255, 255);</p>
<p>background-color: rgba(255, 255, 255, 1.0);</p>
<p>background-color: rgba(255, 255, 255, 0.64);</p>
</div>
