Here is a simple textarea:
<textarea name="content" id="content" class="form-control"></textarea>


Textarea will be expandable based on content height and also for content pasting.

$('textarea#content').on('keyup input', function() { 
    resizeTextarea(this); 
});

function resizeTextarea(obj) {
    var offset = obj.offsetHeight - obj.clientHeight;
    $(obj).css('height', 'auto').css('height', obj.scrollHeight + offset);
}
