What best practices should PHP beginners follow when dealing with dynamic content that requires resizing, like interactive maps?

When dealing with dynamic content that requires resizing, such as interactive maps, PHP beginners should utilize responsive design techniques to ensure the content adapts to different screen sizes. This can be achieved by using CSS media queries to adjust the layout based on the device's screen width. Additionally, beginners should consider using JavaScript libraries like Leaflet or Google Maps API for interactive map functionalities.

// Example of using CSS media queries for responsive design
echo '<style>
    .map-container {
        width: 100%;
        height: 400px;
    }

    @media (min-width: 768px) {
        .map-container {
            height: 600px;
        }
    }
</style>';

// Example of embedding a Google Map using Google Maps API
echo '<div class="map-container">
    <iframe
        width="100%"
        height="100%"
        frameborder="0" style="border:0"
        src="https://www.google.com/maps/embed/v1/place?key=YOUR_API_KEY&q=Space+Needle,Seattle+WA"
        allowfullscreen>
    </iframe>
</div>';
