title: why HTML Codes and css are not working on browser?
body: <p>I am creating a simple website using <code>vscode</code> and <code>wamp</code> but the problem is that when I change any html nothing happens. actually I have two input tags and <code>divs</code> but they don't appear.
  I disabled the cache from chrome dev tools and meta tags but nothing happens and I tried <code>xampp</code> but nothing happens again.</p>
  
  <p>any help ?</p>
  
  <p><strong>HTML::</strong></p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html lang="en"&gt;
      &lt;head&gt;
          &lt;title&gt;Admin&lt;/title&gt;
          &lt;meta http-equiv="cache-control" content="max-age=0" /&gt;
          &lt;meta http-equiv="cache-control" content="no-cache" /&gt;
          &lt;meta http-equiv="pragma" content="no-cache" /&gt;
          &lt;link href="index.css" type="text/css" rel="stylesheet"/&gt;
          &lt;script src="register_ajax.js" type="text/javascript"/&gt;
      &lt;/head&gt;
      &lt;body&gt;
          &lt;div class="box"&gt;
              Username:
              &lt;input type="text" name="username"/&gt;
              Password:
              &lt;input type="text" name="password"/&gt;
          &lt;/div&gt;
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p><strong>CSS::</strong></p>
  
  <pre><code>* {
      margin: 0;
      padding: 0;
  }
  
  body {
      background-color: rgb(186, 196, 38);
  }
  
  .box {
      background-color: rgb(0, 0, 0);
      width: 100%;
      height: 50px;
      border: 1px solid rgb(75, 35, 35);
  }
  
  input {
      width: 100px;
      height: 50px;
  }
  </code></pre>
  
  <p><strong>UPDATE::</strong></p>
  
  <p>when I change <code>css</code> background color of body for testing the color never changes although I disabled cache in dev tools. however when I open dev tools while refreshing the color changes but the html is still invisible as if I didn't write any html</p>
