Is there any css class or attribute for pointer:cursor
in bootstrap 4 specially for button or link?
The cursor: pointer;
rule has been restored, so buttons will now by default have the cursor on hover:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">
<button type="button" class="btn btn-success">Sample Button</button>
No, there isn't. You need to make some custom CSS for this.
If you just need a link that looks like a button (with pointer), use this:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css">
<a class="btn btn-success" href="#" role="button">Sample Button</a>
