title: How do I change heading from H2 to H3 with custom css?
body: <p>I am using this google maps plugin that doesn't allow you to change style of title of the map. Developers told me to change it with custom CSS.</p>
  <p>Since I am a beginner, I don't know how to do that since I don't have id of the element, just the class.</p>
  <p>This is the line that when I change from h2 to h3 does what I want it to do, but that's only in inspector. I need to apply this permanently.</p>
  <pre><code>&lt;h2 class=&quot;widgettitle&quot;&gt;Marinas and tours&lt;/h2&gt;
  </code></pre>
  <p>And then the only widgettitle I could find in plugin files was the following code, and after changing it from h2 to h3, it does absolutely nothing:</p>
  <pre><code>  // initialize widgets
    static function widgets_init() {
      $options = GMWP::get_options();
  
      register_widget('GoogleMapsWidget');
  
      if (!$options['disable_sidebar']) {
        register_sidebar( array(
          'name' =&gt; __('Google Maps Widget PRO hidden sidebar', 'google-maps-widget'),
          'id' =&gt; 'google-maps-widget-hidden',
          'description' =&gt; __('Widgets in this area will never be shown anywhere in the theme. Area only helps you to build maps that are displayed with shortcodes.', 'google-maps-widget'),
          'before_widget' =&gt; '&lt;li id=&quot;%1$s&quot; class=&quot;widget %2$s&quot;&gt;',
          'after_widget'  =&gt; '&lt;/li&gt;',
          'before_title'  =&gt; '&lt;h2 class=&quot;widgettitle&quot;&gt;',
          'after_title'   =&gt; '&lt;/h2&gt;',
        ));
      } // if activated
    } // widgets_init
  </code></pre>
  <p>I hope I can get some help with this</p>
