Warnings using Netbeans 8.2 and Bootstrap 4

Question

Using Bootstrap 4 a lot of warnings show up in Netbeans vs. 8.2 saying that certain classes are not found – all the classes belong to Bootstrap 4. This is rather irritating. These warnings however don't seem to influence the project. The css file is imported using CDN.

    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/css/bootstrap.min.css" integrity="sha384-/Y6pD6FV/Vv2HJnA6t+vslU6fwYXjCFtcEpHbNJ0lyAFsXTsjBbfaDjzALeQsN6M" crossorigin="anonymous">

What is the reason for these warnings and how can I get rid of them?

Answer 1

Hi just ignore that message , the tag is OK but netbeans show you a error cause the tag is too big and contains the property integrity. Everything is ok in your app. Try with another IDE and the error is not aviable.
