title: remove excess margin or padding of form in html using css
body: <p><img src="https://i.stack.imgur.com/GSW18.png" alt="form" />
  This is my form in html the blue one is the entire form and the orange one with red border is the excess margin of the form i wanted to remove this on i tried using</p>
  <pre><code>form{
  margin:0;
  padding:0;
  }
  </code></pre>
  <p>This is approach is not the successful since the margin is still there. And the only way to remove this is excess margin is the margin of form.
  Any idea is appreciated.</p>
