Set The Background Color Using Hex Color Code

Hex color code with the background-color property is the most popular way to set the HTML background color. Hex color has a hashtag '#' and an RRGGBB color code (#RRGGBB). This is an example of applying a Hex color code directly to the HTML element.

Example 3:

        <!DOCTYPE html>
        <html>
        <head>
            <title>Document</title>
        </head>
            <body style="background-color:#FFFFFF">

                <div style="background-color:#FF0000">
                    <h2>Coloring the background of div Element Using Hex color</h2>
                    <p>Hex Color #FF0000</p>
                </div>

                <div style="background-color:#00FF00">
                    <h2>Coloring the background of div Element Using Hex color</h2>
                    <p>Hex Color #00FF00</p>
                </div>

                <div style="background-color:#0000FF">
                    <h2>Coloring the background of div Element Using Hex color</h2>
                    <p>Hex Color #0000FF</p>

Set The Background Color Using HTML Color Name

A second way to set the background color in HTML is to use an HTML color name. The color name is the easiest way to change the color in the HTML document. Just type the color name like a Red, Green, or Blue with the background-color property.

Example 4:

        <!DOCTYPE html>
        <html>
        <head>
            <title>Document</title>
        </head>
            <body style="background-color:white">

                <div style="background-color:Red">
                    <h2>Coloring the background of div Element Using Color Name</h2>
                    <p>Color Name Red</p>
                </div>

                <div style="background-color:Green">
                    <h2>Coloring the background of div Element Using Color Name</h2>
                    <p>Color Name Green</p>
                </div>

                <div style="background-color:Blue">
                    <h2>Coloring the background of div Element Using Color Name</h2>
                    <p>Color Name Blue</p>
                </div>

                <div style="background-color:cyan">
                    <h2>Coloring the background of div Element Using Color Name</h2>
                    <p>Color Name Cyan</p>
                </div>

                <div style="background-color:magenta">
                    <h2>Coloring the background of div Element Using Color Name</h2>
                    <p>Color Name Magenta</p>
                </div>

                <div style="background-color:yellow">
                    <h2>Coloring the background of div Element Using Color Name</h2>
                    <p>Color Name Yellow</p>
                </div>

        </body>
        </html>

Set The Background Color using RGB Color Values

Now, we'll set the HTML background-color property using the RGB values. Use the same style attribute as before, but, replace the Hex Color or Color Name with the RGB Values.

Example 5:

            <!DOCTYPE html>
            <html>
            <head>
                <title>Document</title>
            </head>
                <body style="background-color:rgb(255,255,255)">

                    <div style="background-color:rgb(255,0,0)">
                        <h2>Coloring the background of div Element Using RGB values</h2>
                        <p>RGB values rgb(255,0,0)</p>
                    </div>

                    <div style="background-color:rgb(0,255,0)">
                        <h2>Coloring the background of div Element Using RGB values</h2>
                        <p>RGB values rgb(0,255,0)</p>
                    </div>

                    <div style="background-color:rgb(0,0,255)">
                        <h2>Coloring the background of div Element Using RGB values</h2>
                        <p>RGB values rgb(0,0,255)</p>
                    </div>

            </body>
            </html>

This is how the HTML code above will be displayed in a browser:

HTML5 Tutorial : Set or Change HTML Background Color - using RGB Color Value

When using the RGB values, you have the additional option to set specifies the level of opacity with the alpha channel. That will control the transparency level of the background. The alpha is declared with the "a". If alpha is used, the format code is "rgba". The value of alpha is 0 and 1, 0 for full transparency and 1 for opaque. This is an example of using the "rgba" values.

Example 6:

            <!DOCTYPE html>
            <html>
            <head>
                <title>Document</title>
            </head>
                <body style="background-color:rgb(255,255,255)">

                    <div style="background-color:rgba(255,0,0,0.5)">
                        <h2>Coloring the background of div Element Using RGB with Alpha</h2>
                        <p>rgba(255,0,0,0.5)</p>
                    </div>

                    <div style="background-color:rgba(0,255,0,0.5)">
                        <h2>Coloring the background of div Element Using RGB with Alpha</h2>
                        <p>rgba(0,255,0,0.5)</p>
                    </div>

                    <div style="background-color:rgba(0,0,255,0.5)">
                        <h2>Coloring the background of div Element Using RGB with Alpha</h2>
                        <p>rgba(0,0,255,0.5)</p>
                    </div>

            </body>
            </html>

Set The Background color using HSL color values

The HSL Color Values are less popular than the ways before. The HSL is Hue, Saturation, and Lightness. Just follow the same syntax as RGB values, to use them to set HTML Background color.

Example 7:

        <!DOCTYPE html>
        <html>
        <head>
            <title>Document</title>
        </head>
        <body style="background-color:hsl(0,100%,50%)">
        </body>
        </html>

This is how the HTML code above will be displayed in a browser:

HTML5 Tutorial : Set or Change HTML Background Color - using HSL Color Value


Same as RGB, you can also add the alpha channel to set the level of opacity to the HSL values.

Example 8:

        <!DOCTYPE html>
        <html>
        <head>
            <title>Document</title>
        </head>
        <body style="background-color:hsl(0,100%,100%))">

            <div style="background-color:hsla(0,100%,50%,0.5)">
                <h2>Coloring the background of div Element Using HSL with Alpha</h2>
                <p>hsla(0,100%,50%,0.5)</p>
            </div>

        </body>
        </html>

This is how the HTML code above will be displayed in a browser:

That are several ways to set or change HTML background color. It's so easy and simple, remember this if you want to set the color, use the "style" attribute and CSS background-color property. The syntax is like this:
