This is an example of a date-picker, designed using HTML, CSS, JavaScript, and Bootstrap framework 4. A jquery plugin has been used to implement the functionality of the date picker and the CSS properties of the form. The body of the form is given a background color as #AA00FF. The calendar button is created as a warning type button and given a color as #fff. The input date filed is given a border value of 1px solid #ed433e. In a focus event, the input date field takes a border effect of #f8c146. The jquery library has been used to scroll through the dates and months of the calendar. The min year is defined as 1970 and the range of years is defined as 10, in JavaScript. The calendar is given a fade-in animation, and the format of the date is set as m/d/y in JavaScript.
