What is the DOM?

The Document Object Model is a tree-shaped representation of your HTML. JavaScript can read, add, remove, and modify any node in this tree — that's DOM manipulation.

Essential Methods

  • querySelector / querySelectorAll — find elements by CSS selector
  • createElement / appendChild — build and insert new nodes
  • classList.add / toggle / remove — manage CSS classes
  • setAttribute / removeAttribute — change HTML attributes
