Let’s say you have a certain number of words in a textbox, how can you do that if there are not enough characters to receive a message? c #
What you are asking is not clear.
I guess you may be wondering how do I specificy the maximum number of characters allowed in a textbox. if so you can use the attribute MAXLENGTH like below:
<input type="text" name="username" id="username" maxlength="10">
In the code above the user can only enter a username of 10 characters.
