I thought maybe this method was removed in the new version of jQuery 3.1.1, but connecting the old version 1.11.0 still doesn’t have a smooth appearance. What's the matter?
$(document).ready(function(){ $('div').text('Ля-ля').fadeIn(1000); }); div { width: 200px; height: 300px; background: black; color: red; } <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script> <div></div>
