使用CSS:out-of-range选择器设置<input>元素的样式,使其值超出指定范围。
您可以尝试运行以下代码来实现:out-of-range选择器:
<!DOCTYPE html> <html> <head> <style> input:out-of-range { border: 3px dashed orange; background: yellow; } </style> </head> <body> <input type = "number" min = "5" max = "10" value = "15"> <p>The style only works for the value entered out of range</p> </body> </html>
