What is the CSS property that can be used as an alternative to <IFRAME> in PHP?

When trying to include external content in a webpage, using <IFRAME> tags can sometimes cause issues with responsiveness and styling. An alternative to using <IFRAME> is to use the CSS property "display: inline-block;" along with PHP to include the external content. This allows for better control over the styling and layout of the included content. 

&lt;?php
  $external_content = file_get_contents(&#039;http://example.com/external-content.html&#039;);
?&gt;

&lt;div class=&quot;external-content&quot;&gt;
  &lt;?php echo $external_content; ?&gt;
&lt;/div&gt;

&lt;style&gt;
  .external-content {
    display: inline-block;
    width: 100%;
    max-width: 100%;
    overflow: hidden;
  }
&lt;/style&gt;
