We can use the :hover selector to modify the style of the mouse hovering over the button.
Tips: We can use the transition-duration attribute to set the speed of the "hover" effect:

We can use the opacity attribute to add transparency to the button (it looks similar to the "disabled" attribute effect).
Tips: We can add the cursor attribute and set it to "not-allowed" to set a disabled image:
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>php中文网(php.cn)</title> <style> .button { background-color: #4CAF50; /* Green */ border: none; color: white; padding: 15px 32px; text-align: center; text-decoration: none; display: inline-block; font-size: 16px; margin: 4px 2px; cursor: pointer; } .disabled { opacity: 0.6; cursor: not-allowed; } </style> </head> <body> <h2>禁用按钮</h2> <button class="button">正常按钮</button> <button class="button disabled">禁用按钮</button> </body> </html>

button width
By default, the size of the button Determined by the text content on the button (matching length based on text content). We can use the width attribute to set the width of the button:
Tips: If you want to set a fixed width, you can use pixels (px) as the unit. If you want to set a responsive button, you can set it as a percentage. .
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>php中文网(php.cn)</title> <style> .button { background-color: #4CAF50; /* Green */ border: none; color: white; padding: 15px 32px; text-align: center; text-decoration: none; display: inline-block; font-size: 16px; margin: 4px 2px; cursor: pointer; } .button1 {width: 250px;} .button2 {width: 50%;} .button3 { padding-left: 0; padding-right: 0; width: 100%; } </style> </head> <body> <h2>按钮宽度</h2> <button class="button button1">250px</button><br> <button class="button button2">50%</button><br> <button class="button button3">100%</button> </body> </html>
