How do CSS3 properties achieve scrolling effects on web pages?

Introduction: With the development of the Internet, web design is paying more and more attention to user experience. In web design, scrolling effect is a very common animation effect. By using CSS3 properties, we can easily achieve various cool scrolling effects. This article will introduce how to use CSS3 properties to achieve scrolling effects in web pages, and provide code examples for readers' reference.

1. Use the CSS3 attribute transition to achieve the scrolling effect

The transition attribute can add a transition effect to the element. We can use the transition attribute to add a scrolling effect to the page element. The following is a sample code:

.container {
  overflow-y: scroll;
  height: 300px;
  transition: transform 0.3s cubic-bezier(0.165, 0.84, 0.44, 1);
}

.container:hover {
  transform: translateY(-50px);
}

.content {
  height: 1000px;
  width: 100%;
}

In the above code, we first set the fixed height and overflow-y attributes for the .container element so that scroll bars appear when the content exceeds the height of the container. Then, we added a scrolling effect to the .container element using the transition attribute, where the transform attribute is used so that the container element moves up 50px when the mouse is hovered. By adjusting the value of the transition attribute,
you can control the speed and easing effect of the scrolling effect.

2. Use the CSS3 attribute scroll-behavior to achieve smooth scrolling

The scroll-behavior attribute can add a smooth transition effect to the browser scrolling behavior. The following is a sample code:

html {
  scroll-behavior: smooth;
}

In the above code, we can achieve a smooth transition effect when the browser scrolls by setting the scroll-behavior attribute to smooth. This effect will be applied to the scrolling behavior of the entire page, there is no need to add scrolling effects separately for each element.

3. Use CSS3 attribute animation to achieve scrolling effect

The animation attribute can be used to create a continuous animation effect. We can use the animation attribute to achieve the scrolling effect on the web page. The following is a sample code:

.container {
  height: 300px;
  overflow-y: scroll;
}

@keyframes scroll {
  0% {
    transform: translateY(0);
  }
  100% {
    transform: translateY(-100%);
  }
}

.container:hover {
  animation: scroll 2s linear infinite;
}

In the above code, we first set the fixed height and overflow-y attributes for the .container element so that scroll bars appear when the content exceeds the height of the container. Then, we use @keyframes to define an animation called scroll that does not move the element at 0% and moves 100% upward at 100%. Finally, we use the animation attribute on the .container element and set the time and speed of the scroll animation. By adjusting the value of the animation property, you can control the speed and direction of the scrolling effect.

Summary:

In this article, we introduced how to use CSS3 properties to achieve scrolling effects in web pages, and provided corresponding code examples. By using CSS3 properties such as transition, scroll-behavior and animation, we can easily achieve various cool scrolling effects and improve the user experience of web pages. Readers can select and modify the corresponding code examples according to their own needs to achieve the scrolling effect they want. I hope this article will be helpful to everyone in implementing scrolling effects in web design.
