How to implement horizontal U-shaped step bar component?

Construction of custom horizontal U-shaped step bar components

In web development, it is often necessary to create step bars of different shapes to meet specific needs, such as the horizontal U-shaped step bars discussed in this article. This article will explore how to build such components.

Many developers seek ready-made components or CSS solutions to implement horizontal U-shaped step bars.

Solution

Although there may not be any ready-made components that directly provide "horizontal U-shaped step bars", we can achieve similar effects by combining existing components and custom CSS. The following figure shows an approximate horizontal U-shaped step bar design:

This design is not a perfect U-shaped shape, but simulates the U-shaped effect through clever layout and style. Implementation methods usually involve the following steps:

1. HTML structure: Use<div> Elements build the main structure of the step bar and use sub-<code><div> Elements represent each step. Consider using semantic HTML5 elements, e.g.<code><li> The element is in<code><ol> or<code><ul> in the list for better organization of steps.</ul>

CSS style: This is the key to achieving U-shaped effects. You need to use the border-radius property of CSS to create rounded corners, and control the shape of the step bar and the width of each step by adjusting margin , padding , and width properties. You may need to use pseudo-elements ( ::before and ::after ) to create curve parts at both ends of the U. Flexbox or Grid layouts can simplify the layout and alignment of step bars.

JavaScript (optional): If you need to update the progress or status of the step bar dynamically, such as highlighting the current step, you need to use JavaScript to manipulate DOM elements and CSS classes.

In some developer communities and code bases, implementation codes and tutorials similar to step bars can be found. These codes can be used as reference and foundation to modify and adjust to suit the specific U-shaped step bar design. It should be noted that the final effect depends on the specific CSS style and HTML structure, and needs to be adjusted and optimized according to actual needs.
