Create a personalized front-end progress bar: with ring and mouse prompts
In front-end development, it is often necessary to create custom progress bars that meet the design draft requirements. For example, a progress bar with a central ring and displays prompt information when the mouse is hovering. This article will explore how to achieve this effect.
According to design requirements, we can consider the following implementation solutions:
Solution 1: Use ready-made UI component libraries (such as Element UI Progress components)
This approach is quick and convenient, but it is often difficult to precisely control the details of the progress bar, such as adding custom rings in the center, and limited flexibility in style adjustments.
Solution 2: Pure native JavaScript implementation
Through HTML, CSS, and JavaScript native code, we can fully control every aspect of the progress bar and achieve highly customized effects. This is the recommended solution in this article.
Solution 3: Other methods
Other solutions include using third-party libraries for frameworks such as React and Vue, or using CSS3 animation to achieve progress bar effects.
Let's dive into how to solve the core problem:
-
Central ring effect:
We can represent the progress bar with one
divelement and use anotherdivelement as the central ring. The precise determination of the ring is located in the center of the progress bar throughposition: absoluteof CSS. The circular effect of the ring is created byborder-radiusproperty of CSS. For specific implementation, you can consider: the progress bardivsetting floats to the right, the length is dynamically calculated based on the progress percentage, and then the ring is absolutely positioned at the end of the progress bar. -
Mouse hover prompt message:
Add
mousemoveevent listener to the progress bar. In the event handling function, the current progress percentage is calculated based on the mouse position and the corresponding prompt information is displayed dynamically, such as using atooltipelement.
Through the above methods, we can create a custom progress bar that fully meets the requirements of the design draft, and has a high degree of style and functional flexibility.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.
