As shown in the above program, we have used the code inside $(document).ready which is an event which fires up when document is ready. It will run once the page document object model is ready for JavaScript code to execute.
$(“:input”).css(“border”,”2px solid green”); line defines input selector which selects all the elements of type input. It uses CSS style property to set all input elements border with green color.
The :valid selector allows to select input elements that contain valid content determined by its type attribute.
