You can use the BEGIN_EXPORT/END_EXPORT pair to include a literal HTML
DIV tag around your target code block. Try this:

    Wrapped code block in a div with a custom class:

    #+BEGIN_EXPORT html
    <div class="myclass">
    #+END_EXPORT

    #+BEGIN_SRC c
    #include <stdio.h>
    int main(int argc, char* argv[])
    {
        printf("This is wrapped in the div\n");
        return 0;
    }
    #+END_SRC

    #+BEGIN_EXPORT html
    </div>
    #+END_EXPORT

    Normal codeblock without:

    #+BEGIN_SRC c
    #include <stdio.h>
    int main(int argc, char* argv[])
    {
        printf("This is not wrapped in anything unusual\n");
        return 0;
    }
    #+END_SRC

Note how one of the EXPORT blocks wraps the opening tag of the DIV and
the other one wraps the closing tag.
