Step 1:Create index.html file and implement below code.
<textarea id="text-content" cols="70" rows="4" onKeyup="count_remaining_character()" placeholder="At least 100 character"></textarea> <h2 id="character-count" align="right">150</h2>
Step 2:Implement jQuery to count characters.
<script>
function count_remaining_character() {
var max_length = 100;
var character_entered = $('#text-content').val().length;
var character_remaining = max_length - character_entered;
$('#character-count').html(character_remaining);
if (max_length < character_entered) {
$('#character-count').css('color', '#FF0000');
} else {
$('#character-count').css('color', '#A0A0A0');
}
}
</script>
