Create a button with an electrical arc effect using HTML/CSS

picture[1]-Create a button with an electrical arc effect using HTML/CSS - PANDA-PANDA

Creating an electrical arc effect purely with HTML and CSS is quite complex since CSS is primarily intended for styling and layout. Simulating an electrical arc effect would typically involve JavaScript or a canvas element for more complex animations. However, I can provide a simple example of a button with a basic “electric” effect using CSS animations:
