Comment: I have ignored the powerful functions of HTML5 before, but I don’t know that most of the data need to be verified by myself with it, and I don’t need to add-ons to display the calendar. I will share some small functions with you.
1.Email input box to automatically verify the validity of the email.<!DOCTYPE HTML>
<html>
<body>
<form action="#" method="get">
E-mail: <input type="email"/>
<input type="submit"/>
</form>
</body>
</html>
2.number digital input, verify that it is correct, and the start and end bit can be set.
<!DOCTYPE HTML>
<html>
<body>
<form action="#" method="get">
<input type="number" step="5" min="5"max="20" value="0"/>
<input type="submit"/>
</form>
</body>
</html>
3. The URL input box can verify the validity of URL input.

4.Date pickers (date, month, week, time, datetime, datetime-local) selection box, you can select date, time, month, and week.

5. Datalist input selection.
