title: HTML submit button shadow border issue
body: <pre><code>input[type=submit] {
      float: left;
      font-size: 14px;
      width: 30%;
      height: auto;
      text-align: center;
      font-weight: normal;
      line-height: 30px;
      word-wrap: break-word;
      margin-left: 34.998721%;
      margin-top: 20px;
      clear: both;
      min-height: 0px;
      font-family: helvetica;
      color: rgb(255, 255, 255);
      background-color: rgb(0, 154, 222);
      border-top-left-radius: 3px;
      border-top-right-radius: 3px;
      border-bottom-right-radius: 3px;
      border-bottom-left-radius: 3px;
  }
  </code></pre>
  
  <p>So when I apply this styles to the <code>&lt;p&gt;</code> tag it looks:</p>
  
  <p><a href="https://i.stack.imgur.com/tajMm.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/tajMm.png" alt="enter image description here"></a></p>
  
  <p>but when I apply it for submit button it looks with some borders around it:</p>
  
  <p>How to remove this border?</p>
