Telephone input field can be created using type=”tel”: <input type="tel" name="phone_num" id="phone_num"/> This looks like every other input field, with the difference that it optimizes the keyboard. Certain platforms like tablets, or smartphones will pop-up only-numeric keyboard for this input field. It is hard to enforce particular regular expression through HTML because of variety of phone number formats used along with differences in country codes, and number separators.
When date input was added by HTML5, many believed that it would offer the users a friendly, interactive and known method of entering a date on a website. However; this new addition has failed to live up to the expectations and the major reason behind it remains the fickle nature of the format of the input given by the user. Originally, the date input attribute was designed as a form element to pick values through a datepicker.
