Modern Approaches for Changing Backgrounds
These days, web design has its unique complexities, and one of the designers' concerns is making changes to the background without needing to alter the HTML structure or use JavaScript. The good news is that tools and CSS techniques provide us with this possibility to achieve this creatively.
One of the best ways to implement this is through CSS Animation and Keyframes. With this technique, we can change backgrounds in an attractive manner without adding a line of JavaScript code or touching the HTML.
To do this, we first need to define a CSS class that includes animations to change the color or background image of the element in question. Then, by applying that class to the targeted element, changes will automatically take effect.
The advantage of this method is that everything is centralized in CSS files, and it has a higher flexibility for managing fashionably appealing designs. Additionally, this technique enhances the usability of websites and their applications in professional projects.
Practical Example
body {
animation: changeBackground 10s infinite;
}
@keyframes changeBackground {
0% {
background-color: #FF5733;
}
50% {
background-color: #33FFBD;
}
100% {
background-color: #FF5733;
}
}
Code Explanation
body: This selector affects the entire body of the web page and alters its appearance.
animation: changeBackground 10s infinite;: This line applies an animation named
changeBackground which repeats every 10 seconds in a seamless loop.@keyframes changeBackground: Here, the keyframes are defined that specify the color changes.
0%, 50%, and 100%: These percentages indicate the progress of the animation and represent color changes at each stage.
