How can using CSS and <div> elements instead of tables improve the design and layout of a PHP-driven website?

Using CSS and <div> elements instead of tables can improve the design and layout of a PHP-driven website by allowing for more flexibility, responsiveness, and cleaner code. CSS provides more control over styling and positioning elements on the page, leading to a more visually appealing design. Additionally, using <div> elements allows for better organization of content and easier customization of the layout.

&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
  &lt;style&gt;
    .container {
      display: flex;
      justify-content: center;
      align-items: center;
      height: 100vh;
    }
    
    .content {
      padding: 20px;
      background-color: #f0f0f0;
      border: 1px solid #ccc;
      border-radius: 5px;
    }
  &lt;/style&gt;
&lt;/head&gt;
&lt;body&gt;
  &lt;div class=&quot;container&quot;&gt;
    &lt;div class=&quot;content&quot;&gt;
      &lt;h1&gt;Welcome to my PHP-driven website!&lt;/h1&gt;
      &lt;p&gt;This is some example content.&lt;/p&gt;
    &lt;/div&gt;
  &lt;/div&gt;
&lt;/body&gt;
&lt;/html&gt;
