How to achieve high gradient effect in css3

It can be achieved by using animation effect.

The animation attribute can set the animation effect of the element:
animation-name specifies the keyframe name that needs to be bound to the selector. .
animation-duration Specifies the time it takes to complete the animation, in seconds or milliseconds.
animation-timing-function specifies the speed curve of animation.
animation-delay Specifies the delay before the animation starts.
animation-iteration-count specifies the number of times the animation should play.
animation-direction specifies whether the animation should be played in reverse in turn.

The syntax is:

animation: name duration timing-function delay iteration-count direction;

Height gradients can use the transform attribute

The transform attribute applies a 2D or 3D transformation to an element. This property allows us to rotate, scale, move or tilt the element.

The example is as follows:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
    <style>
        div{
            width:100px;
            height:100px;
            background-color:pink;
            animation:fadenum 5s;
        }
        @keyframes fadenum{
   100%{height:300px;}
}
    </style>
</head>
<body>

How to Use useState() Hook in Functional React ComponentsApr 30, 2025 am 12:25 AM

useState allows state to be added in function components because it removes obstacles between class components and function components, making the latter equally powerful. The steps to using useState include: 1) importing the useState hook, 2) initializing the state, 3) using the state and updating the function.

React's View-Focused Nature: Managing Complex Application StateApr 30, 2025 am 12:25 AM

React's view focus manages complex application state by introducing additional tools and patterns. 1) React itself does not handle state management, and focuses on mapping states to views. 2) Complex applications need to use Redux, MobX, or ContextAPI to decouple states, making management more structured and predictable.

SEO Challenges with React: Addressing Client-Side Rendering IssuesApr 30, 2025 am 12:19 AM

SEO for React applications can be solved by the following methods: 1. Implement server-side rendering (SSR), such as using Next.js; 2. Use dynamic rendering, such as pre-rendering pages through Prerender.io or Puppeteer; 3. Optimize application performance and use Lighthouse for performance auditing.

Updating State Correctly with useState() in ReactApr 29, 2025 am 12:42 AM

Correct update of useState() state in React requires understanding the details of state management. 1) Use functional updates to handle asynchronous updates. 2) Create a new state object or array to avoid directly modifying the state. 3) Use a single state object to manage complex forms. 4) Use anti-shake technology to optimize performance. These methods can help developers avoid common problems and write more robust React applications.
