Using <input type=number> is expected to be implemented so that the user 
can input a number via some user interface, and the set of allowed 
values depends on other attributes of the element, and may allow numbers 
with a decimal part or with a sign.

To specify that a-z only be accepted, you can use <input type=text 
pattern="[a-z]"> or (if uppercase is to be allowed too) <input type=text 
pattern="[a-zA-Z]">
