How can PHP developers avoid common pitfalls when trying to set window size in their projects?

When setting window size in PHP projects, developers should avoid hardcoding values and instead use responsive design techniques to ensure the layout adapts to different screen sizes. One way to achieve this is by using CSS media queries to define different styles based on the screen width.

<?php
echo '<style>
    @media screen and (max-width: 600px) {
        .window {
            width: 100%;
        }
    }
    @media screen and (min-width: 601px) {
        .window {
            width: 50%;
        }
    }
</style>';
