Question: My setup is:

* Visual Studio 2012
* Qt 5.2.0 from
<http://download.qt-project.org/official_releases/qt/5.2/5.2.0/qt-windows-opensource-5.2.0-msvc2012-x86_64-offline.exe>
* Unzip Qwt from <http://sourceforge.net/projects/qwt/files/qwt/6.1.0/qwt-6.1.0.zip/download> to C:\qwt-6.1.0
* Opened Qt 5.2.0 64-bit for Desktop (MSVC 2012) and ran "qmake qwt.pro"
* Opened VS2012 x64 Native Tools Command Prompt and ran "nmake" and "nmake install"
* Set QWT\_ROOT = C:\qwt-6.1.0
* Added C:\qwt-6.1.0\lib to PATH
* Copied C:\qwt-6.1.0\plugins\designer\qwt\_designer\_plugin.dll to C:\Qt\Qt5.2.0\Tools\QtCreator\bin\plugins\designer

When I open Qt Creator and edit the UI then go to Tools->Form Editor->About Qt Designer Plugins I see "Cannot load library qwt\_designer\_plugin.dll:" but no error or reason.

Answer: 
You could use a [iframe](http://www.w3schools.com/tags/tag_iframe.asp) for applying the mathematical stylesheet only. I don't think it will cost too much speed to load if you're using MathQuill extensively.

I would do something like this:

```
<html>
    <head>
        <link href="bootstrap.css" rel="stylesheet" type="text/css" />
    </head>
    <body>
        <iframe src="math.php#f=2*2"></iframe>
        <iframe src="math.php#f=3*5"></iframe>
    </body>
</html>

```

And then let `math.php` output something like this:

```
<html>
    <head>
        <link href="mathquill.css" rel="stylesheet" type="text/css" />
    </head>
    <body>
        <script>
            // Generate content dynamically with JavaScript from parameter `f` so the this page can be cached.
        </script>
    </body>
</html>

```

Another approach would be creating your own custom bootstrap stylesheet. You can [download](https://github.com/twbs/bootstrap/archive/v3.0.3.zip) the LESS sourcecode on its website.
I just solved mathquill + bootstrap conflict by adding css-resetter from [this answer](https://stackoverflow.com/a/15903168/2031077) into beginning of mathquill.css (change `.reset-this` to `.mathquill-rendered-math *`)
