Last week, we announced that CSS updates were on the way—and now they're here! You can now generate CSS files just as quickly and easily as JS files. In the video below, we give a quick demo of the new functionality. If you have a Smart Script loaded in your project, you can instantly add CSS.

In the demo, we also show how to add CSS in the Webflow designer. Give it a try and let us know what you're building!

Javascript 101: CSS & JS Part II

In the last Javascript 101, we explored how to modify styles with JavaScript to create dynamic websites. We looked at manipulating inline styles, toggling CSS classes, and updating CSS variables to respond to user input. Each approach gave us a different level of control over styling changes, and by keeping animations smooth and maintainable, we can create interactive user experiences.

Now, let’s combine what we learned last week with CSS transitions and animations. We’ll use CSS transitions for smooth property changes and @keyframes animations for more complex effects.

​

```
<style>
.box {
width: 100px;
height: 100px;
background-color: lightblue;
position: relative;
transition: background-color 0.5s ease; /* Transition for color changes */
}

@keyframes moveBox {
0% { left: 0; }
50% { left: 100px; background-color: tomato; } /* Color changes midway */
100% { left: 200px; background-color: skyblue; }
}

.animate {
animation: moveBox 2s forwards; /* Triggers the movement animation */
}​
</style>
​
<button id="animateBtn">Animate Box</button>
<div id="box" class="box"></div>
​
<script>
const button = document.getElementById('animateBtn');
const box = document.getElementById('box');
button.addEventListener('click', () => {
box.classList.add('animate');
});
</script>

```

How It Works:

CSS Transitions: We apply a transition to smoothly change the background color. In this case, the box will smoothly transition its color when it reaches certain stages in the animation.

CSS Animations: We use @keyframes to animate the box’s movement from left to right, changing its position and color at key stages (0%, 50%, and 100%).

User Interaction: Clicking the button adds the animate class to the box, triggering the movement and color change. The animation takes 2 seconds to complete, and the background color smoothly transitions thanks to the transition property.

This approach integrates both CSS transitions for smooth property changes and CSS animations for complex, multi-step movements. By combining them, you can create more engaging user interactions with minimal JavaScript, leveraging the power of CSS for visual effects.

Happy coding!
