Base on BOOTSTRA.386 with tiny modify.
Not Bootstrap 4
Assume your MVC project theme didn't modify before, just replace/add following folder to project.
Content
fonts
Scripts
Then add bootstrap-386.js in App_Start\BundleConfig.cs
.
bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
"~/Scripts/bootstrap.js",
"~/Scripts/bootstrap-386.js"));
If need, add js setting in Views\Shared\_Layout.cshtml
or other place you like to.
<script>
_386 = { onePass: true, speedFactor: 1.5 };
</script>
That's all.
