void main() {
  // Selecting elements
  final div = document.select<Element>('.my-div');
  final allDivs = document.selectAll<Element>('.my-div');

  // Manipulating elements
  div?.text = 'Hello, world!';

  // Working with NodeList
  final nodes = document.querySelectorAll('.node');
  final elements = nodes.toElements();
}
