Determine the background color you want to use. HTML colors are dictated by codes on a per-shade basis. Click a base color you'd like to use in the "Pick a Color" section. Select a shade on the right side of the page. Write down the numeric code to the right of the shade.

Open your HTML file in your favorite text editor. Background color, along with all other style aspects of your page, should be handled using CSS. Add the "html" header to your document. Create a blank line between the "style" tags. Add the "body" element. Method 2. Find your document's "html" header.

It should be near the top of the document. Add the "background-color" property to the "body" element. Type background-color: between the body brackets. Add your desired background color to the "background-color" property.

Type your selected color's numeric code followed by a semicolon next to the "background-color:" element to do so. Review your "style" information. Use "background-color" to apply background colors to other elements.

Just as you set it in the body element, you can use "background-color" to define the backgrounds of other elements such as headers, paragraphs, and so on. Method 3. Understand the basic syntax of this process. You can select multiple colors to have the gradient move between all of them, and you can set a direction or angle for the gradient.

Make a vertical gradient. If you don't specify the direction, the gradient will go from top to bottom. Make a directional gradient. If you'd rather create a gradient that isn't strictly vertical, you can add direction to the gradient in order to change the way the color shift appears.

Use other properties to adjust the gradient. There's a lot more that you can do with gradients. For example, not only can you add more than two colors, you can also put a percentage after each one. This will allow you to set how much spacing you want each color segment to have. Add transparency to your colors.

This will make the color fade. Use the same color to fade from the color to nothing. You'll need to use the rgba function to define the color. The ending value determines the transparency: 0 for solid and 1 for transparent. Review your completed code. Method 4. Add the animation property to the "body" element.

Add your colors to the animation. Now you'll use the keyframes rule to set the background colors through which you'll cycle, as well as the length of time each color will appear on the page.

Again, you'll need separate entries for the different sets of browsers. Review your code. Use the background-size property inside of the "body" element. For example, "background-size: px px" makes the background pixels wide and pixels high. Not Helpful 15 Helpful Not Helpful 20 Helpful My text goes here!
