In web front-end design, circles are widely used. Among them, the design of dividing a circle into two halves has become increasingly popular in recent years. Web designers use this design technique to increase the visual appeal of a web page while maintaining its simplicity. This article will introduce several ways to split a circle in half in a web front-end.
Method 1: Use CSS borders
The first method is to use CSS borders. In this case, we can divide the circular container into two halves by representing the upper and lower halves of the circular container with different border colors. We can create this effect by setting a wider upper half border and a narrower lower half border.
Here is some CSS code to create this effect:
<code>.container { width: 100px; height: 100px; border-radius: 50%; border: 15px solid black; border-bottom: none; } .top { border-color: red; }</code>
In the above code, we create a div element named .container
where Turn it into a circular container by setting the border-radius
property. We then split it in half by setting the top and bottom borders of the border
property. Finally, we use the .top
class to set the border color of the top half to red.
Method 2: Use CSS Transforms
The second method is to use CSS Transforms. In this case, you can use the transform: skew()
attribute and the :before
and :after
pseudo-elements to split the circular container in half.
Here is some CSS code to create this effect:
<code>.container { width: 100px; height: 100px; border-radius: 50%; position: relative; } .container:before, .container:after { content: ""; position: absolute; width: 50%; height: 100%; top: 0; transform-origin: center center; transform: skew(45deg); } .container:before { left: 0; background: black; } .container:after { right: 0; background: red; transform: skew(-45deg); }</code>
In the above code, we create a div element named .container
where Turn it into a circular container by setting the border-radius
property. We then use the :before
and :after
pseudo-elements to create the upper and lower halves. We can create this effect by setting their width and transform: skew()
properties.
Method Three: Use SVG
The third method is to use SVG. In this case, you can use the <path></path>
element to create a semicircular path and combine it with other SVG elements to create a separator effect.
Here is some HTML and SVG code to create this effect:
<code><div class="container"> <svg viewbox="0 0 100 100"> <path d="M50,0 A50,50 0 0 1 100,50 L50,50 Z" fill="black"></path> <circle r="50" cx="50" cy="50" fill="none" stroke="black"></circle> </svg> </div></code>
In the above code, we create a div element named .container
, and add an SVG element inside it. We then created a semicircular path using the <path></path>
element and set its color to black using the fill color. Finally, we create this effect by using round elements and placing them inside a round container.
Conclusion
In web front-end design, the use of circular containers is very common. Splitting a round container in half can increase the visual appeal of the page while keeping it simple. This article describes three ways to split a circular container into two halves in a web frontend: using CSS borders, using CSS Transforms, and using SVG. Each method has its advantages and disadvantages, and you can choose the method that suits you based on your needs.

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 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 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.

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.
