Change the background color of a button with CSS
To change the background color of a button, use the background-color property in CSS. This property allows you to set any color value to customize the button's appearance.
Syntax
button {
background-color: value;
}
Possible Values
| Value | Description |
|---|---|
| Color name | Predefined color names like red, blue, yellow |
| Hex code | Hexadecimal values like #FF0000, #00FF00 |
| RGB | RGB values like rgb(255, 0, 0) |
| HSL | HSL values like hsl(120, 100%, 50%) |
Example: Yellow Background Button
The following example demonstrates how to change a button's background color to yellow −
<!DOCTYPE html>
<html>
<head>
<style>
.btn {
background-color: yellow;
color: black;
padding: 10px 20px;
border: none;
border-radius: 5px;
font-size: 16px;
cursor: pointer;
}
</style>
</head>
<body>
<h2>Button Background Color</h2>
<button class="btn">Click Me</button>
</body>
</html>
A yellow button with black text and rounded corners appears on the page. The button has padding and shows a pointer cursor on hover.
Example: Multiple Color Options
You can create buttons with different background colors using various CSS color formats −
<!DOCTYPE html>
<html>
<head>
<style>
.btn {
padding: 10px 20px;
border: none;
border-radius: 5px;
color: white;
font-size: 16px;
margin: 5px;
cursor: pointer;
}
.btn-red { background-color: #FF4444; }
.btn-green { background-color: rgb(34, 139, 34); }
.btn-blue { background-color: hsl(240, 100%, 50%); }
</style>
</head>
<body>
<h2>Different Background Colors</h2>
<button class="btn btn-red">Red Button</button>
<button class="btn btn-green">Green Button</button>
<button class="btn btn-blue">Blue Button</button>
</body>
</html>
Three buttons appear with different background colors: red (using hex), green (using RGB), and blue (using HSL). All buttons have white text and rounded corners.
Conclusion
The background-color property is the primary way to change a button's background color in CSS. You can use color names, hex codes, RGB, or HSL values to achieve the desired appearance for your buttons.
