html - Using bootstrap with web.py's form -

i using web.py in backed generate form. wanting use bootstraps form class. snippet html

  <form name="test" method="post">    $:form.render()   <input type="submit" name="button" value="login" />   </form> 

which, when generated web.py, turns

<form name="login" method="post" class = "register">  <table>     <tr><th><label for="username">username:</label></th><td><input type="text" id="username" name="username"/></td></tr>     <tr><th><label for="password">password:</label></th><td><input type="password" id="password" name="password"/></td></tr>     <tr><th><label for="password_again">repeat password:</label></th><td><input type="password" id="password_again" name="password_again"/></td></tr> </table> <input type="submit" value="register" /> </form> 

however. makes difficult add bootstrap features code. 1 example directly bootstrap website :

<form>   <fieldset>     <legend>legend</legend>     <label>label name</label>     <input type="text" placeholder="type something…">     <span class="help-block">example block-level text here.</span>     <label class="checkbox">       <input type="checkbox"> check me out     </label>     <button type="submit" class="btn">submit</button>   </fieldset> </form> 

is possible add these sorts of features form?

use $:form.render_css() instead.
