Drupal user registration form I just want to do somthing without using module like profile2, so here is my requirement.

=> theme user registration form for e.g. I already have a beautiful user registration form as static html template which use bootstrap classes for css so how can I implement this html template in my drupal registration form.. 

=> In login form I want to remove tabs LIKE create new account and request new password and enstand of these tab I want to give like just before login button.

let me know if anything not clear.
1. theme user registration form

implement hook_theme:

function MYMODULE_theme()
{
  $return = array(
    'my_custom_registration_form' =&gt; array(
      'render element' =&gt; 'form',
      'template' =&gt; 'my_custom_registration_form'
    ),
  );

  return $return;
}


implement hook_form_alter:

function MYMODULE_form_alter(&amp;$form, &amp;$form_state, $form_id)
{
  //dpm($form_id);
  if ('user_register_form' == $form_id) {
    $form['#theme'] = 'my_custom_registration_form';
  }
}


create my_custom_registration_form.tpl.php file in MYMODULE directory, clear the cache, check if it works;

&lt;?php dpm($form) ?&gt;


copy html from your static file (just form part), put it into my_custom_registration_form.tpl.php, example (this will be different in your case):

&lt;div class="col-md-4"&gt;
  &lt;div class=""&gt;&lt;?php print render($form['DESIRED_FIELD']) ?&gt;&lt;/div&gt;
&lt;/div&gt;
...

//render other fields (hidden fields), without them submit won't work
&lt;?php print drupal_render_children($form) ?&gt;

// or you can render them manually

// &lt;?php print render($form['form_build_id']) ?&gt;
// &lt;?php print render($form['form_token']) ?&gt;
// &lt;?php print render($form['form_id']) ?&gt;


2. In login form i want to remove tabs LIKE create new account and request new password - you can do it with CSS, or by removing $tabs variable from page template (you can create specific page template just for login page),

3. enstand of these tab i want to give like just before login button - 
with hook_form_alter fnction you can add other fields (manage theme) to the form

P>S: dpm() - is from Devel module
