- How to style a progress bar with CSS
- To use CSS to customize progress bar styles, you need to override the browser's default styles with pseudo-elements. The Webkit browser uses -webkit-progress-bar and -webkit-progress-value, and Firefox uses ::-moz-progress-bar. By setting the background, rounded corners and other attributes of these pseudo-elements, you can achieve a beautiful progress bar across the browser, and combine animation and gradients to enhance visual effects. However, if you need to fully control the style, it is recommended to use a div structure to replace native progress elements to ensure consistency.
