A smarter way for integrating bootstrap(or even fr

Question

I am looking for a smarter way for integrating bootstrap classes into my less file ?

What I do at the moment is ,but this has the drawback that not every "subclass" or connected class is going to be inherit for my own control:

.BWForm_form-control {
    .form-control;
}

I solved that issue( connected classes) I took the classes from bootstrap and adjust it to my control:

  /*#region ".BWForm_form-control" addition from bootstrap */

    .BWForm_form-control:-moz-placeholder {
        color: #999999;
    }

    .BWForm_form-control::-moz-placeholder {
        color: #999999;
    }

    .BWForm_form-control:-ms-input-placeholder {
        color: #999999;
    }

    .BWForm_form-control::-webkit-input-placeholder {
        color: #999999;
    }

    .BWForm_form-control:focus {
        border-color: #66afe9;
        outline: 0;
        -webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075), 0 0 8px rgba(102, 175, 233, 0.6);
        box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075), 0 0 8px rgba(102, 175, 233, 0.6);
    }

    .BWForm_form-control[disabled],
    .BWForm_form-control[readonly],
    fieldset[disabled] .BWForm_form-control {
        cursor: not-allowed;
        background-color: #eeeeee;
    }

textarea.BWForm_form-control {
    height: auto;
}

.has-warning .BWForm_form-control {
    border-color: #c09853;
    -webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
    box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
}

    .has-warning .BWForm_form-control:focus {
        border-color: #a47e3c;
        -webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075), 0 0 6px #dbc59e;

    box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
}

    .has-error .BWForm_form-control:focus {

        -webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075), 0 0 6px #d59392;

/*#endregion */

To guarantee the full functionality of bootstrap for my personal controls. But I am sure that is not a clever, stable soultion it's just a fix and temporary solution.

But what is the best approach to create personal controls inherited from bootstrap(or even from another css/less file) whith all the functionality ?

Some Background informations for my project: Important NuGet Pakages:

• Bootstrap (v 3.0.0 ) -> imported in the master page
• Bootstrap.Less (v 2.3.2 ) ->these files I use for impor in "Site.less")
• dotless (v 1.4.0.0)
• html5shiv (v 0.1.0.8)
• Modernizr (v 2.6.2) -> imported in the master page
• Respond JS (v 1.2.0)

Actually I am not using this "Bootstrap.Less (v 2.3.2 )"-nuget package, i just took my bootstrap.css and renamed it to bootstrap.less" and used it to inherit from that new less-file.

Because I still have some issues whith it:

• Link 1
• Link 2
• Link 3

Visual Studio 2013

• MVC5

You can simplify this using extend:

.BWForm_form-control:extend(.form-control all);
