Estoy tratando de evitar que mis elementos se superpongan usando interact.js, pero no tengo idea de cómo hacer que los n elementos puedan hacerlo. ¿Alguien tiene alguna idea? O de alguna otra manera puedo validarlo. Pruebe la solución a esta pregunta, pero no entiendo cómo obtener la lista de elementos para revisarla. ingrese la descripción del enlace aquí

Debido a que su fragmento de código contenía una gran cantidad de HTML no válido, tuve que eliminar la mayor parte para que funcionara. Dedique algún tiempo a hacer HTML válido cuando/si hace su próxima pregunta. Algunos errores que estaban presentes en su código HTML:
<head><br/> es válida pero <div/> no lo es y la forma correcta de escribir algunas etiquetas HTML como input es <input> (sin etiqueta de cierre)</tag> sin etiquetas de inicio <tag> <table> <div> </table> </div>A continuación se muestra la solución que se me ocurrió:

</html>Tenga en cuenta que la detección de colisiones se realiza con el llamado algoritmo de detección de colisiones AABB. Puede que no sea el algoritmo de detección de colisiones más eficiente, pero es uno de los más simples de implementar. Y dado que solo tiene 2 cajas, este algoritmo es suficiente. Si necesita más cajas, este algoritmo se volverá exponencialmente más lento y es posible que desee invertir tiempo en buscar un algoritmo mejor, por ejemplo, un quadtree.
Como necesita una respuesta que use la propiedad de transformación CSS, he creado una nueva respuesta basada en su fragmento de código modificado con partes de mi respuesta anterior. Las colisiones se detectarán en los desplazamientos de transformación y no en las propiedades superior e izquierda. Espero que te ayuden con esta respuesta.
